Sažetak
The aim of the study was to determine the effect of the addition of essential oils and probiotics in the calves feed. The study was conducted on 70 male calves, crossbred Belgian blue cattle and Simmental. The calves are divided into two groups of 35 calves of an average age of 60 days previously weighed and balanced by body weight. The control group was fed a ration without supplements, while essential oils and probiotics were added to the ration of the experimental group. The duration of the study was 77 days. Production traits, i.e. body weight, average daily gain and food conversion, were monitored. The results obtained for body weight were higher in the experimental group than in the control group (5397 : 4918 kg). The results of the average daily gain were also higher in the experimental group than in the control group (0.62 : 0.78 kg). The feed conversion ratio was lower in the experimental group compared to the control (2.10: 1.56 kg / kg). Based on the results it can be concluded that the addition of essential oils and probiotics in calves ration has a positive impact on the monitored production traits.
