    Study Correlates Food Rewards with Positive Responses during Training

    Young horses learn faster and have more positive interactions with humans when they receive food as a reward during
    training, according to a new study presented at the 34th Annual Equine Research Day held in Paris, France, on Feb. 28.
    Yearlings that received grain pellets as compensation for appropriate reactions to vocal commands were up to 40% faster to
    acquire new skills than a control group of yearlings that received no rewards. The training primarily involved respecting the
    words "stop" and "stay" and remaining immobile while the trainer performed certain grooming tasks and veterinary procedures
    on the horse.
    "What we're hoping to do is develop techniques which will allow us to obtain the animal's confidence in us, without using
    constraints," said Carol Sankey, MSc, a PhD candidate in ethology (the study of animal behavior) at the University of Rennes
    in western France, and co-author on the study. At the previous Research Day event, Sankey's team presented findings that
    force can result in a negative relationship between horses and humans.

    A yearling in the study receives a food reward.
    Sankey and her team devised a series of objectives that the yearlings in both the reward and the no-reward groups were
    expected to attain in a consecutive order. After learning to stop and stay by voice command only, each animal learned to wait
    patiently with the leadline draped over its neck while the trainer brushed it, picked its hooves, attached a surcingle, applied
    tendon boots, inserted a thermometer in its rectum, and finally applied a "vapor spray" (simulating applying fly spray or coat
    polish) over its coat. All eight colts and 15 fillies involved in the study received training individually for five minutes per day, five
    days per week, until the entire set of objectives was obtained. The amount of time to achieve each task and the totality of the
    tasks was recorded for both groups.
    On average, the reward group finished their training in 3.7 hours whereas the control group needed 5.2 hours to acquire the
    same tasks. "There wasn't even any overlap," Sankey explained. "The slowest horse in the reward group still learned faster
    than the fastest horse in the control group."
    Additionally, by the end of the training period, horses in the reward group were more likely to voluntarily approach the trainer
    and to remain at a closer distance to her than the control horses were. Sankey noted that the horses in the reward group
    displayed more behaviors considered positive by the researchers, including significantly more sniffing, exploration, and licking
    of the trainer. Horses in the control group were significantly more likely to bite, kick, or fall over during hoof cleaning.
