Outcome of tactile conditioning of neonates, or “imprint training” on selected handling measures in foals.

The study examines how a method called imprint training, which involves conditioning newborn foals (baby horses) through touch, can affect their future behavior towards handling techniques. They found that imprint-trained foals were less resistant to certain handling procedures at three months old.

Research Design

• The researchers compared the behavioral reactions of 19 foals who underwent imprint training (Group A) with those of 21 untrained foals (Group B), who served as control subjects.
• Imprint training began within 10 minutes of birth and involved desensitizing the foals to touch through gentle rubbing. This process was repeated 30-50 times over a span of 45-60 minutes, until the foal no longer resisted and appeared to be relaxed.
• This process was repeated 24 hours post-birth. At this time, a physical examination and blood analysis were also conducted to evaluate the health of the foals.
• In contrast, Group B foals were only subjected to a brief physical examination and blood analysis at 24 hours old. They were not otherwise handled.
• All the foals were then kept in pastures with their mothers, without any further handling until they were three months old. Foals that had to be handled for other reasons before the three-month mark were excluded from the study.

Measures and Evaluation

• At the age of three months, the 28 foals who completed the study were subjected to several handling procedures including restraint, haltering, a full physical examination, touching the entire body, application of a plastic rebreathing bag, intramuscular and intranasal vaccination, and deworming with oral paste.
• The foals’ responses to each procedure were scored on a scale of 1 to 4, with 1 representing no resistance and 4 representing strong resistance that required substantial physical restraint.

Findings

• The researchers found that conditioned foals (Group A) were less resistant to having their front and back legs touched and picked up compared to the untrained foals (Group B).
• In both groups, the majority of the foals displayed low or no resistance when it came to vaccination administration, paste deworming, and blood collection.
• The study concluded that neonatal imprint training seems to result in learned behavior that reduces the self-defensive reactions of three-month-old foals towards limb handling.
