Abstract

An experiment was held in order to test the effects of Tribulus terrestris extract on weight development and health status in calves of Simmental breed in the dairy period. The experiment included calves leveled by gender, body weight, age and paternity. The calves were divided into two groups (control and experimental), the difference between the groups is in the presentation of the plant extract in the diet of calves from the experimental group. During the experiment (lasted 60 days) we controlled health and feed consumption (daily) and the weight development (monthly). The results show higher growth (not significant) with 7.7% and better feed conversion in calves receiving with milk plant extract from Tribulus terrestris to those in the control group. In animals of the experimental group was observed better health status.
