Successful Keeping Experience of the Eurasian Lynx (Lynx lynx) in Barnaul Zoo «Forest Tale»
The article discusses the welfare problems of Eurasian lynx keeping in Barnaul zoo «Forest Tale». In addition, it describes the importance of wild animals behavior research for their wellbeing in captivity. The behavior and calculation of time’s budget for males and females of Eurasian lynx were studied. The Shorygin’s coefficient of behavior similarity was determined (87,2%). During the studies the low level of stereotypical behavior (male — 5,9% and female –3,8%) was observed. The differences in the lynxes’ behavior in the experiments before and after environmental enrichment were analyzed. Stereotyped behavior of lynxes decreased due to olfactory enrichment in males on 24,3%, in females on 18,8%. With alimentary enrichment of the environment the proportion of stereotypes was reduced: in the experiments with frog males on 6,5%, females on 8,7%; in experiments with rat carcass — males on 15,9%, females on 20,3%; in the experiment with the meat under the grass on 0,9 and 1,4%, respectively. Based on our findings, we recommend keeping lynxes in pairs (male — female), with appropriate shelter, varied diet and with changing of scenery, constantly to conduct the experiments on olfactory (ungulates› litter and valerian roots) and alimentary (with alive and mortified food objects) environment enrichment. In conclusion, it is worth noting that friendly attitude toward cats from the side of animals› keepers also affects on their well-being.
