Abstract

There are a few researches about influence of diet regimes on animal behaviour in captivity. Aim of this research, on two groups black and white ruff-eared and ring-tailed lemurs, is to confirm the influence of healthy vegetable based diet on behaviour of individuals. It is known that diet in nature contains complex carbohydrates (fibers), and that fruit in the zoos contains much more simple carbohydrates (glucose, fructose). Diet could be the cause of physiological limitations of individuals in captivity. I did preliminary monitoring and created the table of behaviours for our groups. Monitoring was equal for morning and afternoon sessions in duration of three hours (one before feeding and two after), recording behaviours every two minutes. The results have shown that both groups spent more time resting and digesting, the feeding rate had grown, and their prosocial interactions (positive mutual) increased. The diet change in black and white ruff-eared lemurs caused the significant decrease of agonistic (aggressive) behaviours. The response of both groups depended on group formation and they differed in details, but general conclusion is that diet has influence on the behaviour and it is necessary to test important variables from this research in other circumstances.
