Effects of medical training on two captive Eurasian Lynxes: an evaluation of the behavioural changes

In captive conditions, preventive examinations and routine monitoring are essential for the appropriate management and care of animal health. Medical procedures, and some husbandry routines, frequently require the use of physical and chemical restraint. These methods are associated with increased risk of trauma and higher level of distress for both animals and keepers. Positive reinforcement training techniques are now commonplace for medical and husbandry training in many accredited zoos. By teaching animals to voluntarily participate in medical procedures, the risks and the negative experiences that these involve could be greatly reduced, while improving the relationship between animal and keeper. The objectives of the training plan developed during this project aimed to train two captive Eurasian lynxes (Lynx lynx) to stay still on a platform for at least 5 seconds and replace the use of the target with the hand to facilitate weighting procedures on a scale. Another purpose of the study was to evaluate the feasibility of the training program and its effects on the general behaviour of animals performed throughout the day. Behavioural observations were conducted with continuous focal animal sampling both during and outside the training period. Results showed a variability between the two individuals on the final outcomes and achievements of the training project, particularly due to different learning paces. A reduction of the number of unsuccessful gestures and of cue-response latencies suggests that training sessions were effective. Analysis of data from the extra-training observations were able to detect subtle changes in the behavioural pattern. Results show a greater use of space and increased anticipatory or longing behaviours for training sessions to occur, expressed by the animals after the training period. In the light of the above, it can be argued that training can be considered as a valuable tool for providing a better day to day care of animal health and welfare.
