Sažetak
A study was conducted to determine the effect of a mixture of phytobiotics on health and production traits in suckling calves. The study included two groups; control (K) and experimental (P), with 14 animals in each group evenly distributed by sex (7♂ : 7♀). The study lasted 10 days. Both groups were fed with a milk replacer using a 4 L / calf feeder per day. A mixture of phytobiotics in the amount of 3 g / calf per day was added to the experimental group. The calves were weighed immediately after calving and on the tenth day of the study. Blood sampling for refractometry was performed 48 hours after calving, and for the determination of hematological parameters on the tenth day of the study. In addition to blood sampling on the tenth day of the study, fecal samples were collected. Body weight, average daily gain and feed conversion were monitored by production traits, while passive immunity, hematological indicators and the occurrence of cryptosporidium in faeces were monitored by health indicators. The results of the study did not show statistically significant differences between the observed indicators, but the experimental group had a tendency to higher values (P = 0.088) of body weight and leukocytes (P = 0.082) on the tenth day of the study. In addition, the incidence of cryptosporidium in faeces was lower in the experimental group compared to the control group (3: 6). Based on the obtained results, it can be concluded that the addition of phytobiotics to milk replacer has a potentially beneficial effect on the observed indicators and that further research is needed.
