A Contemporary Approach to Equine Welfare

A Contemporary Approach to Equine WELFARE



This is a review of the current behavioural science regarding the horse.  This paper is a primer on equine behaviour, and portrays the educational approach to fulfill the health and welfare of horses from the horse’s perspective, rather than from the human perspective.  Behavioural study and appreciation of the evolved nature of horses provide the foundation for the contemporary principles of equine welfare.  Friends, forage and locomotion are the long-evolved requirements for healthy horses to facilitate optimum health, performance and healing. 




Equine Behaviour Through Time

Horses began their journey through time 60 million years ago. Three million years ago the footsteps of humans were fossilized next to the hoofprints of horses, suggesting that humans have been contemplating horses for some time. But it was not until perhaps ten thousand years ago that human societies began the dance of domestication with the horse. Over thousands of years, perhaps tens of thousands of years, the horse herds gradually merged with human societies. A shared language described by contemporary scientists as kinetic empathy, a language of movement, and similar compatible social structures facilitated the merging of the two species.

There is archeological evidence that humans had formed an intimate and intermingled relationship with horses by 5500 years ago in Botai, where the horsefolk stabled and milked horses, and probably rode them. Horses provided these early horsefolk with much of the essentials they needed for group survival. It is interesting to note that large domestic dogs lived with these early horsefolk as well, but no other domestic animals. To understand the domestication process is to enhance our appreciation of equine behaviour. Horses apparently became domesticated because they found a niche with people long ago on the steppes of Kazakhstan. Both trained and wild horses existed in this realm south of Russia and west of China. A population of horses more amenable to captivity and taming than their wild counterparts likely provided the stock for the first horse societies. Rather than plucking wild horses out of the wild and taming them, it is thought that over tens of thousands of years a relationship developed in a shared niche.

By the early 20th century the closest living relative to Equus caballus, the Tarpan, had gone extinct. No truly wild horses remain. All of today’s caballine horses are descended from an original, and possibly separate, population of horses that were amenable to being tamed and selectively bred by humans. It appears to have taken tens of thousands of years to fully domesticate the horse, and to eventually attain control of breeding. Breeding initially consisted primarily of selection for docility and amenability to captivity, and later milking, riding, driving, and stabling. In contemporary culture, selective breeding often involves selecting for the best athlete, or attempting to select for the best athlete. In addition to genetics, this presentation will focus on the socialization aspect of raising horses, and portray the importance of nurture on the eventual behavioral and physical health of the adult athlete.

No longer does human society depend on horse society for survival as it once did. Although still bred for trainability, more and more horses are today bred for specific performance goals. These days, horses provide people with entertainment, recreation, sport, esteem, performance, and pleasure, and, as ever, but in fewer and fewer reaches, utility. Other than stockfolk, few others rely on horses to sustain a pastoral livelihood. This new role of the horse requires renewed studies and considerations of equine behavior.

Horsefolk and veterinarians alike remain enticed and intrigued by horses. The science of equine behaviour attempts to appreciate just who horses are, and from the horse perspective. To appreciate the horse perspective, behaviourists explore the evolution and domestication of the horse. We continue to find ourselves attempting to appreciate how the current human/horse relationship came to be so as to facilitate a smooth trouble free relationship with our horses. As well, appropriate breeding, socialization, and training of horses helps minimize behavioural wastage.

To understand where our relationship with the horse is headed, veterinary behaviour practitioners attempt to see where the human/horse relationship has been, and to subsequently help modify and refine the relationship to favour the horse. Humans continue to live with horses and continue to learn from them, as all horsefolk have through time.  Now, however, much less time is spent with horses and learning from horses, so contemporary practitioners must research and make themselves aware of the behavioural principles that were once gleaned from a near-constant exposure to horses through all stages of their development. We study the evolution and domestication of the horse to better help us appreciate the horses we have in our hands today. Evolution and domestication provide a basis for the understanding of equine behaviour. Man has attempted to refine his relationship with the horse ever since the first kid grabbed a mane and swung atop a horse. To become a partner with the flighty, powerful (but trainable and tamable) grazer of the plains remains the horsefolk goal.

Appreciation and sensitivity to all of our caballine horses' evolved preferences results in optimum health and soundness, and therefore optimum performance. A horse cannot be coerced to win the Kentucky Derby. The people must work with the horse, and from the horse’s view. If we understand equine behaviour, we understand what makes horses do our bidding, and do it willingly and well. To this day, horses seek to appease their domesticators much as they appease others in horse societies and herds. Horses are willing learners. This learning behavior is a result of evolutionary development of a complex social lifestyle. More recently, selective breeding has influenced equine behaviour.

The nature of the horse is enhanced by the horse’s social development. Appropriate socialization with other horses in the herd pasture setting best prepares horses to be subsequently trained by horsefolk. Pastured horses train up and learn more efficiently than stabled horses. The appropriate, efficient, and considerate training of horses is highly dependent on their previous socialization by the dam and other horses, as well as their current husbandry situation. Trainability is heavily influenced by the intensity and type of stabling and husbandry, not to mention the type of training. In the latest revolution of horsemanship, the area of appropriate socialization and stabling has not received the attention it deserves.

Horses are a quiet species. They prefer calm, and learn most efficiently in tranquil, familiar settings. Horses must know and be comfortable and secure in their environment to be able to learn as horsefolk hope them to learn. Horsefolk all know what we want from our horses, however in this paper I shall present the science of what our horses want and need from humans, the science of equine behaviour. Equine behaviour is not only the basis of training and trainability, but also the very basis of equine health. To succeed in our endeavors with horses (whatever the our equine goals or pursuits), our horses are best served to receive what they preferentially need and require behaviourally, nutritionally, socially, physically, environmentally, visually, and metabolically. In order to properly care for horses and successfully teach and train horses, horsefolk must know horses. They must know who the gregarious grazers of the plains are. They must know how to properly socialize horses through their growth phase to ensure that their horses grow up to be horses. Horses raised out of the herd context are vulnerable to behavioural insecurities later in life. Most behavioural wastage is due to improper socialization and husbandry.


Rather than being dissimilar to us, horses are much like us. In this presentation, I attempt to clarify humankind's social and communicative similarities to horses. As with people, strong social bonds develop between individual horses and groups of horses. This herd nature results in intense social pair and herd bonds. Horses need other horses. Horses require other horses for security, comfort, and behavioural health. Horses need friends throughout their entire life, first their teaching mother, and then their teaching herd. Today’s domestic horse needs horse friends and human friends, although horses do retain the wherewithal to survive just fine without horsefolk. Horses need friends so greatly and constantly, that horses allow horsefolk to substitute as friends. This is possible because man shares a sociality with domestic horses. We speak their gesture language, and horses speak ours. We share a language of movement, and language described as kinetic empathy.
Domestic horse is no longer human prey, and has not been for thousands of years. Horse has been brought into the circle of humanity, along with a dozen or so other domesticates that share an adequate sociality with mankind to be allowed to develop a mutually beneficial relationship.

Horse and man have co-evolved together for thousands, if not tens of thousands of years. Each knows the other, well, and horses have proven to know the nature of people more consistently than people know the nature of horses. It is paramount that horsefolk appreciate the social and communicative nature of horses, and deal with horses in a fashion that is appropriate to their long-evolved social nature.



In addition to adequate and appropriate sociality and socialization, the importance of the need for near-constant motion is paramount to proper application equine behaviour. Locomotion is essential for horse health. In natural settings, horses move about grazing, playing, trekking, and variety of other movements as much a two-thirds of the time. Abundant movement provides constant connection and communication with the other horses in the herd, and as well, sustains the overall and physiologic functions of the horse. Plentiful locomotor activity facilitates behavioural expression and maintains physiologic health. An essential interdependence exists between horse health and locomotion. Horses evolved to be near-constant walkers and grazers. Horses did not evolve to be confined in stalls and stables, but rather evolved to live in open herd settings. Despite domestication and selective breeding for docility and captivity, horse health remains dependent on locomotion. Locomotion is inherent to grazing. Locomotion is inherent to digestion, to respiration, to metabolism, to hoof health and function, and to joint health. If horses are not allowed to move about freely and socialize with other familiar horses grazing and chewing as they evolved to do, they become metabolically vulnerable and subsequently troubled. Horses deprived of locomotion and constant forage ingestion develop strategies to maintain the motion and oral security they feel they need to survive. When horses are deprived of adequate and abundant locomotion, they develop strategies to keep themselves and their jaws moving, as is their essential and inherent nature. Horses deprived of friends, forage, and locomotion are at risk to develop stereotypies to provide themselves with the movement they need to survive.

The primary premise of equine behavioural health is this: in natural settings, horses walk and graze with other horses two thirds of the time. They take a step and graze, then another step or two grazing and moving along, always observing their surroundings, grazing while in touch with other members of the herd unless playing, occasionally dozing or sleeping, but only under the secure and established watch of others. Horses that are not afforded the opportunity to graze and walk much of the time take up with behaviours to replicate essential locomotion. When stabled, some of the horse's long- evolved survival behaviours become unwanted and unwelcome.

Horses require friends, forage, and locomotion to stay healthy and productive. Additionally, horses need clean air and abundant space for optimum health. In rural settings, these requirements are easy to fulfill. Open grasslands and steppes are the geography and environs from where the most recent predecessors of Equus caballus evolved. The further we remove horses from their social grazer of the plains preferences, the more health issues develop that require treatment and management by veterinarians and horsefolk.

Stabling, stalling, hospitalization and transport all deprive horses of their preferences for friends, forage, and locomotion. Although convenient for horsefolk, stabling is inconvenient for horses. Stabling limits the resources of friends, forage, and locomotion. Stabling creates bad air, and allows pathogens and parasites to travel easily between horses. When stabling is required, horses are best served to have their natural needs re-created in the stable. The air must be kept clean, and forage must be always available. Opportunities for movement and simulation of grazing with friends must be provided in abundance. Once our horses’ behavioural needs are understood, appreciated, and fulfilled, the learning and training can begin. Enrichment strategies re-create the needs of stabled horses. Horses deprived of friends, forage, and locomotion are not able to learn as well as appropriately socialized horses. Those strategies that best replicate the grazer of the plains scenario promote the best health, learning, and performance from horses.

Locomotion and socialization are essential for both horse health and healing. Husbandry, healing, and rehabilitation nearly always benefit from appropriately managed locomotion strategies that are constantly tailored to the horse's healing process. Locomotion is required not only for normal healing, but for normal digestion, respiration, hoof health, circulation, and all other physiologic functions of the horse. Stall rest is at the expense of many systems, especially the hoof and metabolic systems. Digestion and respiration are compromised by confinement and restriction of movement. Metabolic, digestive, circulatory, hoof health, musculoskeletal, and nervous, systems, as well as the all other systems and functions of the horse, are dependent upon adequate and appropriate locomotion for normal functioning and/or healing.

For horses that are hospitalized, paddocked, stabled, and corralled; active implementation and re-creation of the social pasture setting is required to optimize and maintain health and promote healing. Medical conditions are apt to deteriorate in the face of the deprivations of forage, friends, and locomotion created by stabling and hospitalization. Re-creation of a natural setting in the stall is the biggest challenge veterinarians face in maintaining the health of stabled horses.

Stalled horses not only heal poorly, they learn and train poorly. Locomotion, social, and forage deprivations create problems for horses. In addition to appropriate medical treatment, veterinarians and stable managers must creatively provide horses with abundant socialization, forage, and locomotion to maintain health and facilitate healing within the parameters of acceptable medical and surgical treatment. Restriction of locomotion to facilitate healing necessitates the implementation of enrichment strategies to simulate locomotion, including massage, passive flexion, and a wide variety of physical therapies.

Horses also heal horsefolk, and those horsefolk that implement these healing strategies often experience a sense of healing themselves, it seems. The human/horse bond runs deep. Domestication of the horse is a co-evolving evolutionary process. The human perspective is being shaped by the horse's perspective these days. Appreciation of the science of equine behavior and equitation is encouraged to support the renewed interest in equine medicine and welfare, and to facilitate the veterinarian’s role of providing horses with their essential needs.

What Horses Need



Horses require friends, forage, and locomotion, and they require those essential needs 24/7. Of course, herds at pasture have all that, and it is our duty to make sure that stalled horses get as much of that as we can provide. For stalled horses, these natural circumstances must be re-created in the stable to maintain health, happiness, and sound athleticism. Stalled horses require miles of daily walking to maintain optimum health and performance.
Horses are happy to please horsefolk who know how to please horses.
All of the systems of the horse are dependent on abundant daily locomotion. Hoof integrity and health, respiratory and metabolic function, behavioral contentment, musculoskeletal health, respiratory health, digestive health, athletic ability, and trainability are all dependent on abundant locomotion, appropriate 24/7 forage availability, and friends.

Keeping your horses warm in the winter...


Horses evolved in the Northern Hemisphere's northern latitudes and are well adapted to cold provided they live in a herd, have 24/7 appropriate forage and fresh water (although it is reported horses can live on certain snows, don't try this at home), and move a lot through the day. Place your feeders so the horses have to move about to eat, and never let the forage disappear completely, please. Movement is the nature of the horse. Heavy horses require more movement rather than less hay. Keep your ponies moving to keep them warm and healthy. Digestion is dependent on locomotion. Mobile horses require miles of walking each and every day to maintain optimal health. Humans often fail their horses by depriving them of the abundant locomotion they require each day to stay healthy. Every system of the horse is dependent on abundant daily locomotion.
In summary, to keep warm in cold weather horses require appropriate and constant forage 24/7, friends, and abundant movement. Shelter is always nice, provided the air remains fresh and pure and never is dusty or full of particulates. Sheltering is often responsible for the development of heaves, so find a balance for your horses, my friends.
Whenever you see horses standing around in the same place all day, expect trouble, veterinary bills, as well as hoof, digestive, training, respiratory, and metabolic trouble. Stalled or corralled horses need to get and and move miles everyday, so saddle up, kids, and get your horses moving. To move is to thrive if you are a horse.

Racehorse Soundness and Safety

Abundant daily locomotion of stabled racehorses is essential to develop, enhance, and maintain pulmonary and musculoskeletal soundness. Abundant daily walking and grazing are easy to accomplish at nearly all of the American racing venues. Time seems to be only restraint, taking the time to care for stabled horses as they should be cared for to reduce their current dependence on medication and the resultant untoward side-effects. Something as simple as abundant daily walking to improve racing safety and integrity should not be overlooked. The current practices, both pharmaceutical and husbandry-related, have failed the horses, thus the United States continues to experience unacceptable breakdown rates not experienced or tolerated elsewhere in the world.
Education is the key, education of those caring for the horses and responsible for their durability. Stabled racehorses require miles of daily walking to induce, maintain, and enhance musculoskeletal soundness. The same walking activity that enhances pulmonary health, enhances limb health and integrity. Lasix has allowed trainers to lock their horses down most of the day, resulting in limb fragility, which is expressed as breakdowns at the race track. The long term-solution lies not so much in regulation as education.
Please note, that when people are hospitalized and bedridden, some of earliest medical personnel to attend them are respiratory therapists. The respiratory therapists, understanding how locomotion is essential for respiratory function, employ a variety of lung exercises and pulmonary assessments to make sure the pulmonary health of the of the hospitalized patients is maintained. Racehorses are for all practical pulmonary purposes hospitalized. Locomotion and movement are restricted and deprived by stabling. Specific pulmonary conditioning efforts are necessary to enhance and maintain pulmonary health and resilience of all stabled performance horses. For a horse, to move is to breath deeply and healthily, and to breath is to move. When stabling is required, natural must be-recreated in the stable, or the horse will suffer deterioration of soundness of both wind and limb.
Pulmonary health is heavily dependent upon abundant daily locomotion. Please appreciate that America's legalized Lasix allows pulmonary health to be compromised, the pharmaceutical scrim responsible for overall racehorse fragility. Pre-race Lasix allows trainers to race horses deprived of appropriate pulmonary conditioning. Restricted locomotion results in lung (and limb) deterioration, which is the primary basis for all of the breakdown and safety issues plaguing the sport. Lasix facilitates the substandard horsemanship that is responsible for much of the contemporary racehorse fragility. Day before injections of NSAIDs likewise perpetuate vulnerability to catastrophic injuries. Pulmonary health is connected to limb health. To allow deterioration of one system is to allow deterioration of the other. Lasix facilitates the racing of horses with compromised lungs. When the lungs are allowed to deteriorate by restricted locomotion, the limbs deteriorate likewise. Bone density and joint integrity are dependent on miles of daily movement, as near-constant movement is the essential nature of horses. Digestion, metabolism, hoof health and durability are all dependent on abundant daily locomotion.
Education can improve the health and welfare of horses.
The key to equine welfare lies in equine behavior education, which delivers an understanding and appreciation of pulmonary and limb health and soundness, and what is required to assure soundness of wind and limb. The same conditioning protocols that ensure pulmonary health and resistance to EIPH are the same protocols that enhance soundness of limb. The solution to improve racing health, soundness, safety, and integrity are relatively simple, and are based on the science of equine behavior, and the need for horses to receive abundant daily locomotion in addition to their race-conditioning regimens.

Equine Behavior, a primer


Horses began their journey through time 60 million years ago. Three million years ago the footsteps of man were fossilized next to the hoofprints of horses, suggesting that humans have been contemplating horses for some time. But it was not until perhaps ten thousand years ago that man began the dance of domestication with horse, the horse who became Equus caballus. There is archeological evidence that man formed a close relationship with horses by 5500 years ago in Botai, Khazakstan where the horsefolk kept and milked horses, probably rode them, this after millenia of hunting horses for food. Both trained and wild horses co-existed in this realm south of Russia and west of China. Trained horses soon spread throughout the world, civilization of man the result. By the early 20th century the predecessor to man's newest animal partner, the tarpan, had gone extinct. No truly wild horses remain, excepting perhaps the Przewalski, which has a different number of chromosomes than the horse, and is not thought to be horse's progenitor. To the best of our knowledge, all horses today are descended from tamed and selectively bred horses. The progenitor of the horse, the tarpan Equus ferus, went missing from our planet in 1918. One gauge of domestication is the extinction of the progenitor, and mankind has managed that. The horse of today is with us to stay, it seems, and can live with humans, or without them.
Today horsefolk remain enticed by horses and we find ourselves still attempting to appreciate how this human/horse relationship came to be, and where the relationship is headed, much as mankind has since the first girl grabbed a mane and swung on a horse to become a partner with the flighty, powerful (but trainable and tamable) grazer of the plains.
Equine Behaviour differs from the other horse pursuits as equine behavior is taught from the horse's perspective while the other disciplines are taught from the human perspective. Equine veterinary behaviourists understand that appreciation and sensitivity to all of our horses' evolved preferences results in optimum health and soundness, and therefore optimum performance. Behavior is a result of evolutionary development and selective breeding (nature). The genetics are shaped by the social environment, nutrition, neonatal and juvenile development and training (nurture). Equine behaviour is heavily influenced by socialization. Subsequently, behaviour is affected by the intensity and type of stabling and husbandry. Horses need to grow up to be horses as taught by horses to eventually lead behaviourally healthy lives. When grown, horses must be allowed to be horses with other horses to enhance willing partnerships with horsefolk. When stabled, natural must be re-created for the horse as we shall see.
Horses are a quiet species. They prefer calm, and learn most efficiently in tranquil, familiar settings. In emulating the horse, our interactions here will be communicatively soft and calm so as not to unnecessarily upset or excite our herd. Now if there is something valid to be concerned about, say a certain enlightenment, or concern about a welfare issue, or perhaps a training or stabling method that does not align with the horse's perspective, then we appropriately share our views with the others. 
We all know what we want from our horses, however here we shall explore the science of what our horses want and need from us, the science of equine behaviour. To succeed in our endeavors with horses (whatever equine goals or pursuits), our horses are best served to receive what they preferentially need and want behaviourally, nutritionally, socially, physically, environmentally, visually, and metabolically. In order to properly care for horses and successfully teach horses, we must know them, the diligent social grazers of the plains they are. 
Rather than dissimilar to us, horses are much like us. In this class we will focus on humankind's social and communicative similarities to horses. As with people, strong interdependence develops between individuals, intense social pair and herd bonds. Horses need other horses, and when they are dependent on people, they need a lot of time spent with those horsefolk and their other horses. 
An interdependence also exists between health and locomotion. Horses evolved to be near-constant walkers and grazers. Horse health remains dependent on locomotion and grazing, or facsimiles thereof. If horses are not allowed to exercise freely, or socialize with other familiar horses, nibbling and chewing as they evolved to do, they develop strategies to maintain the motion and oral security they feel they need to survive. 
A primary premise of equine behavioural health is this: In natural settings, horses walk and graze together two thirds of the time. They take a step and graze, another step or two, always observing their surroundings, grazing while in touch with other members of the herd unless playing, dozing or sleeping under the watch of others. 
Horses that are not afforded the opportunity to graze and walk much of the time take up with behaviours to replicate essential locomotion. When stabled, some of the horse's long-evolved survival behaviours become unwanted and unwelcome. 
Away we graze, moving through our coursework as a herd of horses might graze open range, connectedly, in communication with one another, learning, forever learning.

Measuring Equine Welfare

Equine welfare is measured by the amount of medication and veterinary care horses require in their given situation. The more medication and veterinary services required for a stable or discipline, the poorer the welfare situation is for the horses. Inadequate husbandry creates the need for medication. The more medication required, the poorer the equine welfare.
Properly cared for and stabled horses seldom need veterinary attention and require very few if any drugs to maintain their health and performance aspirations. American racehorses would be better served by providing more appropriate horse-friendly care rather than continued injections of raceday drugs. Permissive drug programs create substandard care. The massive amounts of Lasix, cortisone, and NSAIDs administered to American racehorses is reflective of the poor welfare standards the industry allows. Permissive drug programs perpetuate substandard care. As well, the breakdown and unsoundness so prevalent in American horseracing are directly proportional to the amount of veterinary services (drugs administered and injected) horses receive. The more drugs horses receive the more they breakdown. Heavy use of drugs reflects poor welfare. American racehorses are poorly cared for as reflected by the drugs trainers claim the horses require.
Thoroughbred welfare is the issue that needs addressed. American racehorses need better care. A high incidence of EIPH is reflective of substandard care. Racehorses need much more locomotion and out of stall activities than they presently receive. Abundant locomotion enhances soundness of wind and limb. Horses require several hours of afternoon activities each day to promote and sustain health of limb and wind including hand walking and grazing, lungeing, hill and dale conditioning, measured turnout, pasturing, massage, passive flexion, swimming, play, and variety of other activities that keep them moving.

Drugs and Racehorses


Drugs and Racehorses

Phenylbutazone seemed a miracle drug when the stuff began entering the bloodstreams of racehorses in the 1960s. I was collecting the post-race urine that concentrated the metabolites of that drug during the ’60s, and as a teenager I became acutely aware of drugs and racehorses.
What a soothing anti-inflammatory effect bute brought to racehorses in those simpler days when its use first became widespread. The alleviation of certain lamenesses was dramatic. “Really sweet stuff,” I remember Wright Haggerty’s Kentucky groom telling me on the Shelby, Montana, backside in 1965 as he pestelled up tiny white 100-milligram dog pills he had received from my father, the attending and regulatory veterinarian (thus my job as urine catcher). The original medical plan, being that most racing jurisdictions back then prohibited the use of any and all drugs, was to use bute for training. The groom mixed the white powder into a mash, and fed his eager and waiting racehorse, who trained like Seabiscuit the next morning.
Bute cools hot joints and quiets inflamed tendons to desirable medical effect, allowing horses to return to training and racing sooner than otherwise, allowing them to maintain their conditioning. Tight, cool legs and hooves are necessary to continue conditioning the racehorse. If there is excess fluid in a joint, or swelling within a hoof, conditioning is generally counterproductive as further inflammation and damage follow exercise.
Bute was first used to facilitate continued training by quieting certain injuries or inflammations, and was especially effective when used conscientiously and conservatively. In a certain sense and in compassionate, knowing hands the drug provided humane relief to the rigors of racehorse life. The question quickly became: Could bute enhance performance? It was not a question for long. The answer was yes. Bute was and is the cleanest boost ever for a horse with mild inflammation in need of relief. The stuff could move a horse up, as they say, without a mental, or stimulant effect, but with an anti-inflammatory effect.
Two horses being equal, however, bute generally won’t make a horse with quieted inflammation run faster than a horse without joint, bone, or tendon inflammation. In a sense, bute restores normal overall biomechanical function. The nonsteroidal anti-inflammatory drug takes the heat out of mildly inflamed legs, feet, and joints, and this can be good in considerate hands.
Bute also became useful in the sense that it was diagnostic, or so the mind-set went at the time. If you administered bute and your horse went back to training and eating and being a sound horse after laming up a bit, then it was concluded that the condition was not significant enough to warrant rest, only to warrant bute. Bute, then, could be used to assess the severity of the lameness in racehorses. Some did not consider bute-responsive conditions serious, and this is one line of reasoning that eventually allowed the legalization of bute. There were medical arguments for its use in racing horses, medical arguments made by veterinarians and drug companies.
The conditions that bute administration does not resolve or effectively manage are considered problematic, and those conditions generally warrant rest, rather than more intensive treatment. Today, however, if bute does not manage the condition, more intense treatments are used, and more intense drugs are used.
Rest is the oldest and most effective treatment for lameness. In the history of horse doctoring, no treatment is more effective. The horse has a tremendous potential to heal musculoskeletal injuries if returned to natural pasture conditions, grazing the plains with herdmates. The problem is that it takes a full year of rest to cure many conditions racehorses develop, and at least months for others. No one has time to rest racehorses, to wait a year, and then take eight months to recondition the horse. With racehorses the clock is ticking, fast. If drugs can save time with racehorses, they are used for just that. And that is the case these days. The industry has transcended bute. The monthly veterinary bills at Belmont and Aqueduct often exceed the monthly training fee. Ask any owner.
If conditions are diagnosed accurately and thoroughly, and drugs are dosed properly and administered in a timely manner, doctors can reduce problematic inflammation in a given leg or joint, which in turn protects the rest of the horse by minimizing the risk of extra strain on other joints and limbs to compensate for the painful injured joint. However carefully dosed and administered, however, this brand of racehorse sports medicine puts more pressure on the weakened, and now treated joint, and herein lies the danger. In addition to systemic medication given intravenously to treat joint inflammation, cortisone is injected directly into joints and tendon sheaths to get a significant anti-inflammatory effect. Cortisone is in a different class of drugs called steroids, which can be used more specifically than bute to reduce the inflammation in a specific joint.
When there is swelling in a joint or tendon sheath, excess synovial fluid is secreted, distending the joint structures, and in some cases, deforming them, making for irregular movement. The reason for excess fluid in a joint is most often damage to the sensitive joint structures; damage to the synovial membranes, articular cartilages, ligaments, tendons, and underlying bone, any or all of the above. Damaged joints are weakened joints. They are inflamed joints, and in racehorses, many become cortisone-injected joints: weakened joints that are quieted down with cortisone. Why? Horse joints need to flow smoothly. Imagine an abraded joint surface, or a tendon that loses its lubrication as is passes over a running, moving joint, the resultant pain, swelling, inflammation, increased friction, and impaired function. If there is rough movement in one joint, the roughness is relayed throughout the horse’s musculoskeletal system, increasing the burden on the other legs and joints.
Intra-articular injection of a joint with cortisone is a potent treatment. In certain veterinarians hands it can be used beautifully. The most commonly injected joint is the fetlock, which is also the most commonly fractured joint. The reality is that most of fractured joints were cortisoned joints, although this information is inaccessible because of medical confidentiality. Bute is less intense, less potent, and a more conservative, safer remedy. The original idea was that legalized bute would replace joint injections, or that was part of the intent. That has not been the case.
Phenylbutazone, or bute, abbreviated from the early popular brand Butazolodin, is a nonsteroidal anti-inflammatory drug very similar to aspirin. Those who understand the pharmaceutical principles of aspirin understand phenylbutazone. Bute reduces inflammation, and subsequent to that, pain. That is the sequence, anti-inflammatory first, with subsequent pain relief. As a result of reduced inflammation, there is restoration of function accompanying relief of the joint pain.
If you consider aspirin a painkiller, then I suppose you can consider bute one, as well. Bute lasts longer, a day or two, while aspirin is more quickly metabolized in the horse, a matter of hours. The sustained anti-inflammatory effect of bute is especially therapeutic to horses. Prolonged anti-inflammatory relief allows the interdependent musculoskeletal system of the horse to redistribute weight appropriately. Lameness anywhere imbalances the horse. In a sense, bute can improve the balance by providing anti-inflammatory relief of the inflamed parts.
Initially, drugs for racehorses being illegal, bute was used to facilitate training and not so much enhance racing. That came next. The medication got to working pretty darn good, and in time trainers began administering bute to their horses closer and closer to racing, and soon the testing folk started picking it up. Matt Lytle was one trainer who taught me about bute, the smile it put on his face until Croff Lake, one of his horses, suffered a bad test after winning the Oilfield Handicap in Shelby, Montana, one of those years in the mid-’60s. Lost his purse and sort of soiled his reputation all because of a shade of bute in the urine.
Later, I heard him defend the drug, and his use of it: he gave it for the horses well-being, he claimed, and knowing Matt and his connection to his horses, I did not doubt his intent and compassion. Pain relief is compassionate, especially the sort of racehorse pain relief bute provided. The problem today is that a good thing, bute, or medication in general, has been taken too far. In the passion of competition and in a world of big money, horses have become victims of a misguided pharmaceutical culture.
My dad, having dispensed the bute, sampled Matt’s horse after it won the Oilfield Handicap. I was the one who caught Croff Lake’s urine, which tested positive. Then the next spring a winning horse tested positive in the Kentucky Derby. Rather than further restrict drug use to remedy the situation, the industry legalized drugs. From that time, horse racing shifted from a covert medication culture to an overt medication culture, which has been recently brought to its knees.
After hundreds of other doping incidents, there came a general consensus that if so many felt the need to use bute, maybe it should be O.K. to run on. After all, it was only a type of aspirin. And perhaps its legalization would eliminate the need for other more abrasive medications, such as opiates and amphetamines, and local anesthetics. Some even thought it would reduce the urge to administer intra-articular injections of cortisone. Not the case.
By the time I graduated from vet school and began practicing at Playfair Racecourse in the late ’70s, I could legally treat racehorses with nearly everything except stimulants, opiates or depressants. That left a lot of anti-inflammatory drugs, antihistamines, hormones, steroids and bleeding medications to administer to running racehorses, not to mention a multitude of vitamins, amino acids and minerals thought to help a horse endure the rigors of confinement training and racing.
Now virtually all racehorses run on bute and Lasix, and now with too many fractured fetlocks the medication has to be reduced. Bute wasn’t enough. No drug is. Legal bute engendered a drug culture. The ideology that more conservative use of potent medications would follow legalization of bute did not prove up. More intense drugs and medical treatments followed, rather than less. The pharmaceutical adaptability of the racehorse has been exceeded. Horse racing has to wean itself from its addiction to drugs that no longer help, but instead weaken horses. Racing jurisdictions are in the process of rolling back drug use. The trend should continue as a part of the remedy to reduce breakdowns. Foreign horse racing jurisdictions run without medication, and their safety records are better than the United States’. Horses running clean are less likely to break down than those running on medication.
