New Model Needed for Race-Day Treatments

By SID GUSTAFSON

The white horse emerged late last year representing promise to restore a limping game; a new age of clean racing, race-day-medication-free racing; but the white horse hung coming down the lane. Too much Lasix, it seems; resulting in an inability to hold sway.

American trainers and their attending veterinarians remain unwilling to sacrifice their race-day needles just yet. They are reluctant to give up medicating racehorses before the runners head over to the paddock. Rather than educating trainers how to appropriately care for racehorse lungs and limbs as attending veterinarians should, the race-day vets continue to inject drugs, and more drugs. The more drugs attending veterinarians administer, the more they are paid. The only fees attending veterinarians generate are fees for administering medication. Attending veterinarians are paid in direct proportion to the drugs they administer.

One can easily see how that may sway their opinion regarding drugs, and their decisions to administer drugs to racehorses. There are no veterinary fees for consults or advice on the backside. Herein lies a significant part of the medication problem. Attending veterinarians have failed to learn how to charge for medical consults. To give the advice to let a horse run clean is to not be paid for anything, although it is often the best advice a veterinarian could give to a trainer regarding a champion runner. To be able to deliver sound horsemanship advice and be eligible to be willingly paid for his knowledge and professional acumen, an attending vet needs to appreciate the true nature of horses and learn how to manage bleeding and unsoundness in more appropriate, less pharmaceutical, fashions. When attending veterinarians come to understand as much about equine behavior and welfare as they know about manipulating horses with drugs, life will begin to improve for horses.

It is simply not good form to go after horses with needles and drugs before they race. It is not fair. It is not right. It is not medically or morally appropriate. It has been demonstrated to be a practice that is harmful to horses, a practice that when allowed is applied to virtually all horses rather than horses in need, regardless of their limb and lung health. To medicate nearly every horse who races in America with bute and Lasix is not the practice of veterinary medicine, but rather some sort of medication sham. Veterinarians should know better. As has long been suspected in ethical racing jurisdictions around the world, medicating racehorses on race day has proved to be an inappropriate and unethical practice, not to be allowed, much less tolerated. The regulators of racing in the 1960s had it right. No drugs allowed, no doping whatsoever permitted, regardless of the dope or the doper. The results of race-day medication will always be the same: rogue winners, rogue losers, more medical issues incited than resolved, more deterioration of the horses and the sport, shorter careers, more fragility, and more breakdowns. More public concern and scrutiny.

It has long been public knowledge that horse racing requires strident antidoping regulations and enforcement. It is becoming increasingly evident that the attending veterinarians are the people who require intense monitoring. Once entrusted with the health and welfare of racehorses afforded by their professional standing and education, they can no longer be counted upon to practice right by the horse. Racehorses and drugs have had a long, albeit dangerous, marriage, and the attending veterinarians have been the ministers of the nefarious relationship.

To relentlessly medicate racehorses, rather than to nurture and care for them properly in accord with their long-evolved nature, has resulted in tragedy reaching to the very top of the American horseracing game. The more medication horses are given, the less carefully their natural needs and tendencies are tended to, and the more fragile they become.

Rather than drugs, appropriate care and horsemanship are the keys to appropriately manage bleeding and unsoundness in horses. Racing was originally designed to be drug free, and that clean-running notion of ethical regulation holds to this day. It is generally accepted by most welfare-progressive societies around the world that trainers and their attending veterinarians cannot be relied upon to represent the health and welfare of their horses when money and fame are to be gained by pharmaceutical manipulation of their charges. Permissible race-day drug injections have deteriorated the game considerably.

All of this year’s Derby runners are scheduled to race on Lasix, and most all of them will also get injected with the adjunct bleeder medication which the Kentucky Horse Racing Commission allows to be injected into horses before the race, the drug known as Kentucky Red, or carbazochrome. Good stuff, that Kentucky Red. If one drug is good, two must be better, or so goes the veterinary reasoning and fee structure of attending veterinarians.

In addition to pushing drugs into the Derby runners’ veins shortly before they race, the veterinarians will also be very busy injecting the horses the day before they race. Never enough vetting has become the backside mantra. In addition to the race-day cocktail the Derby runners and all the other runners on the card will be receiving before they run, most of the runners will be medicated with phenylbutazone 24 hours before the Derby, along with various other additionally permitted nonsteroidal, anti-inflammatory drugs, as well as a surfeit of other permissible medications. Most Derby horses will have a cornucopia of drugs circulating through their systems by the time they reach the starting gate, enough drugs to float a battleship, as the saying goes, drugs that allow trainers to exceed the adaptability of their racehorses.

The reality, now demonstrated worldwide, is that horses and their riders are best served to race clean. The fewer drugs the better as far as the horses’ health and welfare are concerned. The public prefers an even field, and a fair horse race. Clean racing evens the field and protects horses, riders, and horseplayers. Clean racing selects for the best horse; the most durable, soundest, best developed, best bred, and fastest horse. Clean racing allows horses to persevere and prevail over a long career of running. Clean racing allows the best horses to prevail time and again, to win the Triple Crown.

Across the oceans, clean runners are currently competing more safely than the drug-addled American horses. Foreign runners break down less, and bleed little, if any, more than the heavily medicated American horses. Everywhere but in America, bleeding and soundness are managed with horsemanship and appropriate husbandry as bleeding and unsoundness should be managed. The correlation between race-day drug use and breakdowns has become painfully evident. The more drugs a jurisdiction permits to be administered to horses, the more breakdowns the horses racing in the jurisdiction experience. The time to ban race-day drugs is now. Horses cannot speak, file lawsuits, or tweet, therefore much of the medication abuse of racehorses in veterinary hands goes unnoticed as unreported, excepting, of course those abuses so prevalent and overwhelming that they require reporting by those news outlets genuinely concerned about the health and welfare of racehorses.

Next time, I’ll deliver another rousing sermon from my rabbit hole in the infield: how to race and win without Lasix, and to race and win again, and then win one more time. It is no coincidence that there has not been a Triple Crown winner since Lasix started sapping the vigor and durability out of champion runners in America. The times they are a changin’ for the better for horses, thanks to those who have the creative cause to step forth and take a stand for the health and welfare of Equus caballus.

How to Race Horses without Lasix, Chapter 1

Chapter 1

Horses have long raced without medication the day they run, and appropriately so. Medication is for horses who are sick or unsound. Only healthy horses are qualified to race. Horses that require drugs to race should not be raced until they heal, and can race without medication. Healthy horses race safest.
Trainers who feel they cannot race horses without injecting them with raceday drugs are unqualified horsemen. The concept of fair play precludes the use of drugs to influence the outcome of a race. Horses deserve better than to be medicated on raceday, as over 90% now are. Horses have long successfully raced clean when properly cared for and appropriately conditioned, and have raced more safely than mismanaged horses that require medication to get them around the oval each race. 

Conscientious horsemanship and appropriate husbandry of stabled racehorses manages both EIPH and soundness. Horses need to get out of their stalls each afternoon for a few hours of grazing and walking about, perhaps some lungeing to lung up the lungs and flush the metabolism. Horses are born to move nearly constantly, and it is this near constant movement that appropriately conditions lungs to handle the athletic rigors of a horserace. Humane care of the horses is the answer to managing bleeding and breakdowns, not drugs, my goodness. The bleeding medication issue is entwined with the breakdown issue, as it is the horses medicated for bleeding that breakdown approximately 4X more frequently than clean running horses.

The horses will prevail soon, as the ban on raceday drugs is inevitably necessary to revive the sport and restore integrity to the game. 

Horses everywhere will breath great sighs of relief at not having to be needled with drugs hours before every race they run.

Racehorse Advocacy
The Trouble with Raceday Medications

By Sid Gustafson, DVM

April 12, 2012

Thanks in part to the racehorse advocacy efforts by The Humane Society of the United States and the Humane Society Veterinary Medical Association, a variety of racing jurisdictions are reviewing raceday medication practices and are making advancements to support the drug-free welfare and humane care of racehorses. Raceday medications are in the process of being gradually prohibited, as are the indiscriminate and abusive use of drugs in racehorses in general. It has become clear to many that current racehorse medication practices in the United States and Canada exceed the adaptability of the racehorse, resulting in unnecessary breakdowns, injuries and even death to both horses and jockeys. Rather than drugs, it is the humane care of racehorses that supports soundness of wind and limb.

The practice of administering raceday medications    is being called into question.    Gina Hanf

A variety of groups have responded to the call to provide better care for racehorses. The Kentucky Horse Racing Commission invited The HSUS to testify at its raceday medication hearing in November 2011, and I provided a version of the racehorse advocacy that follows. The Interstate Horse Racing Improvement Act (H.R. 1733/S. 886) is making its way through the U.S. Congress, and is supported by several congressional representatives. Make sure your representative supports this important Act. New York Gov. Andrew Cuomo has called for an investigation of the New York Racing Association breakdowns. The New York Times is running a series of articles exposing the medication charade that has endangered horses and riders for decades in America. The Breeder’s Cup committee has banned raceday Lasix for two-year-olds competing in this year’s race¹.

Drug-free racing will improve stabling, conditioning and husbandry practices for racehorses. Medication has long been a crutch that facilitates the improper care of stabled horses. Rather than alleviate medical conditions, recent data clearly demonstrates that racing medications allow people to exceed racehorse adaptability. Drug use perpetuates fragility in racehorses². Fragility is dangerous for both horses and riders.

To appreciate the principles of equine behavior is to understand what is required to maintain pulmonary health in horses being conditioned to race who are confined to stalls, and it is not drugs. The solution to managing exercise-induced pulmonary hemorrhage (EIPH) and preventing breakdowns is appropriate breeding, development, horsemanship, training and husbandry—not drugs. The care that establishes and enhances pulmonary health and endurance in horses is the same care that enriches stabled horses’ lives. It is the same care that keeps racehorses’ musculoskeletal systems sound. It is humane care that keeps horses on their feet during races. Limb soundness and pulmonary soundness are physiologically entwined.

Horses who are bred, socialized, and developed properly from birth, and who train while living enriched stable lives, are seldom likely to experience performance-impairing EIPH while racing. They are more apt to stay sound of limb. Bleeding in a race is reflective of inadequate care and preparation, of miscalculations and untoward medication practices. Drugs and raceday medications perpetuate substandard horsemanship, artificially suppressing the untoward result (bleeding and breakdowns) of inadequate preparation of the thoroughbred. The solution to manage bleeding and prevent breakdowns in racehorses is to breed, develop, teach, train and care for horses in a horse-sensitive fashion.

Horses evolved as social grazers of the plains; group survivalists moving and grazing together much of the time. Horses require near-constant forage, friends and locomotion to maintain health of wind and limb, even if they are stabled. Racehorses are no exception. The last place a horse evolved to live is in a stall, alone, with a limited view and uncirculated air. The solution to managing racehorse health is proper horsemanship and husbandry, which is sadly lacking at today’s racetracks. Horses prefer to graze together and move nearly constantly in natural settings; to race without drugs, natural conditions have to be re-created in the stable. The equine requirement for near-constant grazing and moving is essential for joint and bone, hoof, metabolic, and pulmonary health. In order for lungs to stay healthy, horses need more movement than they are currently provided. Abundant on- and off-track locomotion is necessary to condition a horse’s lungs. To enhance pulmonary health is to enhance the horse’s entire life and outlook. Not only do properly stabled and trained horses’ lungs hold bleeding in abeyance, they hold sway and win. Pulmonary health and bleeding prevention are dependent on smooth running and biomechanically-sound locomotion.

Horses evolved in the open spaces of the Northern Hemisphere and require the cleanest, purest air to thrive and develop healthy lungs and hearts. Stable air needs to be constantly refreshed to maintain pulmonary health. Ventilation is essential, and enclosed structures are often inadequate in providing the healthy air horses require. Appropriate barn design and stabling practices maintain pulmonary health. Bedding is critical. Clean straw provides stall movement by simulating grazing. Horses stalled on straw are noted to move about with their heads down nibbling and exploring for hours, recreating nature to some degree, keeping their lungs healthy with movement, their respiratory tracts drained by all the head-down nibbling and grazing. This is not enough. For healthy lungs, horses need to get out of their stalls for hours each afternoon. Not only does near-constant movement maintain and enhance pulmonary health, abundant locomotion maintains metabolic health, joint and bone health, hoof health, and digestive health. To enhance, support and maintain lung and limb health without drugs is to enhance the overall health and soundness of the horse.

Appreciating Horses; Equine Behavior and Applied Horsemanship

Appreciating Horses    

Equine Behavior is the basis for Horsemanship
Sid Gustafson DVM

In consideration of the horse’s nature and behavior, horsewomen and horsemen are obligated to provide horses an appropriate environment, unconstrained neonatal development, formation and fulfillment of the mare-foal bond, adequate nutrition, sufficient sociobehavioral circumstances, as well as training and horsemanship modalities based on the horse's innate perspectives and sensitivities.
By nature the horse is a precocious grazer of the plains, a social and herd animal, and flighty. Horsemanship and training are best accomplished through behavioral appreciation of the horse and facilitation of the horse’s nature, rather than by force or coercion. Horses are best trained in a relaxed, calm state. Training that puts the horse into the flight or sympathetic state generated by fear and punishment while restricted by rigs or round pens is discouraged, and not in accordance with acceptable standards of animal training. Horsetraining and horse teaching methods are best based on scientific studies regarding the nature of the horse. Horses learn preferentially in a relaxed state from a calm experienced handler with adept communication skills.
Social behavior in natural feral settings is the 'natural' behavior that 'natural' horsemanship utilizes to appreciate the nature of the horse.
As to dominance, the science reveals that free-ranging horses form social hierarchies that are complex and rarely linear. Under natural open range conditions with adequate resources, horses seldom have the equivalent of an alpha individual because the roles of leadership and defense are more critical than domination. Dominance theory as a training modality is not only discouraged, but appears inappropriate. The formation of order in horse groups sustains collective welfare and enhances group survival, and reflects leadership rather than domination.[1] It is important veterinarians and students of equine behavior appreciate this science.
There is no alpha. Leadership is shared and alternated and variable and context dependent in established harems in natural settings. Dominance is rare, and certainly not prevalent. When present at all, it facilitates group protection and stability. Horses share leadership. Survival is herd based, rather than individual based. The lead mare leads the horses to water and grazing and resting places. She drinks first to make sure the water is safe, rather than because she dominantes the others. Students of equine behaviour appreciate shared leadership and herd stability. Horses seek competent leadership and are willing to accept competent leadership from humans.
The horse is special in retaining the ability to thrive in feral conditions independent of man. This allows us to study their true nature versus their stable nature and to apply that knowledge to their welfare as it pertains to training.
Horse retains the ability to survive without us, and survive well.
It behooves humankind to take care with horses. Sensitive horsefolk respect the 60 million year development of the horse’s social behavior and development. They appreciate equine intelligence in regard to both training and husbandry, and what the future might hold.
Stabling is unnatural. Horses graze and walk together 60-70% of the time under natural circumstances, eating and moving from spot to spot independently but within a few meters of the next horse. Stable managers and horse owners should make every effort to accommodate or recreate these long-evolved herd grazing and life-in-motion preferences for proper physiological function and mental health.

Horses require other horses for proper health and prosperity. Horses prefer the constant companionship of other horses. A horse should seldom be kept alone. Horses being mixed with other horses and expected to share resources should be properly acclimated socially, and be given the required space to adjust to new herds without injury or undue stress. Every effort should be made to provide horses with the social benefit of appropriate companion horses through times of stress and illness.
Horsewomen and men need to appreciate the sensual nature of the horse, and understand the physiological needs of the horse. Horses prefer the open view. If they cannot be in physical contact with other horses, they need to see and smell other horses for proper behavioral functioning and responsiveness.
Water is the most important nutrient, and must be provided in consideration of equine behavioral preferences. Salt is the most important mineral, and should be provided daily in some fashion.
Grazing is the preferred and predominant equine activity. Horses did not evolve to metabolize grains and non-structured carbohydrates, or to remain stationary for even short periods of time. Serious metabolic issues develop when horses become sedentary grain eaters, and this lifestyle should not be imposed on horses.
Play and sleep are naturally occurring preferences that require accommodation however horses are housed or stabled, as deprivation results in behavioral deterioration.
Horses are physiologically dependent on shared social grooming and sensual contact companionship. If stabling precludes these preferences from fulfillment, then every effort need be applied to replace or recreate these needs on a daily basis.
These behavioral considerations apply to horses in transport, and for those horses too, however unwanted, man is obligated to provide the proper environment, social functioning, nutrition, medical care, and exercise to sufficiently assure health and comfort.
As to performance, every care and precaution need be taken to avoid exceeding the adaptability of the horse. All of the horse's normal natural sensation should remain fully intact and functional without undue pharmaceutical influence. The horse's metabolic, physical, medical, and behavioral limitations are best be monitored by equine veterinary professionals on an intense comprehensive basis.
Professional veterinary societies and organizations are encouraged to provide education regarding equine behavior.

Racehorse Advocacy, The End of Raceday Medications

It is the same care that keeps racehorses’ musculoskeletal systems sound. It is humane care that keeps horses on their feet during races.

Horses with healthy lungs and sound limbs are content and fulfilled horses whose lives their caretakers adequately and extensively enrich. Lung health is supported by limb health. Appropriate husbandry and training maintains and establishes soundness of both wind and limb. Breathing and running are biologically intertwined on the track, a breath per stride. To stride correctly is to breathe correctly. To breathe correctly is to breathe soundly, and race sound. Limb soundness and pulmonary soundness are physiologically entwined.

Horses who are bred, socialized, and developed properly from birth, and who train while living enriched stable lives are seldom likely to experience performance-impairing EIPH while racing. They are more apt to stay sound of limb. Humane care of the horse prevents bleeding, my friends. Humane care of the horse prevents breakdowns. Pulmonary health is reflective of appropriate husbandry, breeding, training, nutrition, and the abundant provisions of forage, friends, and perhaps most importantly, locomotion. Bleeding in a race is reflective of inadequate care and preparation, of miscalculations and untoward medication practices. Drugs and raceday medications perpetuate substandard horsemanship, artificially suppressing the untoward result (bleeding and breakdowns) of inadequate preparation of the thoroughbred. Drugs are no longer the solution. Humane care of the horse based on evolved behavioral needs is the solution to safe horseracing.

The solution to manage bleeding and prevent breakdowns in racehorses is to breed, develop, teach, train, and care for horses in a horse-sensitive fashion. Horses evolved as social grazers of the plains, group survivalists moving and grazing together much of the time. Horses require near-constant forage, friends, and locomotion to maintain health of wind and limb, even if they are stabled. Racehorses are no exception. The last place a horse evolved to live is in a stall, alone, with a limited view and uncirculated air. Training and husbandry need to be a good deal for horses in order for horses to maintain healthy partnerships with people. Pulmonary health is reflective of overall health and soundness in horses. Pulmonary health is reflective of limb soundness.

In order to maintain pulmonary health, natural conditions need to be re-created in the stable. The solution to managing racehorse health is proper horsemanship and husbandry, which is sadly lacking at today’s racetracks.

In order for lungs to stay healthy, horses need more movement than they are currently provided. Abundant on track and off-track locomotion is necessary to condition a horse’s lungs. Lungs deteriorate when movement is restricted by excessive confinement in a stall. Horses breath all day long, and trainers need to appreciate abundant movement is required through much of the day to maintain pulmonary strength and health.

To enhance pulmonary health is to enhance the horse’s entire life and outlook. Not only do properly stabled and trained horses’ lungs hold bleeding in abeyance, they hold sway and win. Pulmonary health and bleeding prevention are dependent on smooth running and biomechanically sound locomotion.
