Abstract
The new living conditions that animals get into in the early neonatal period are associated with diseases caused by maintenance and feeding, as well as untimely veterinary treatments for both mothers and newborns. Therefore, it is extremely important to introduce ingredients into their diet that contribute to successful adaptation. The aim of the research was to study the effect of the feed additive «Tanamin Zn» on the leukocyte formula of blood and the manifestation of diarrhea syndrome in calves. During the experiment, the experimental animals-analogues were divided into groups. The experiment was carried out on calves of the black-and-white breed (Bessonovsky type) in the conditions of the collective farm-stud farm named after V.Ya. Gorin, Belgorod region. Groups (12 heads in each) were formed taking into account origin, sex, live weight (LW) and age. The I-K – control group included calves who received the main diet (MD), and the II group included calves who received, in addition to MD, tanamine Zn at a dose of 0,05 g / kg of live weight / day during the entire dairy period (60 days). It was found that the total number of leukocytes during feeding (1;30;60 days) of the supplement and during the aftereffect (90 days) was within the physiological norm with different directions of changes in the number of eosinophils, basophils, neutrophils, lymphocytes and monocytes. In addition, we have shown a decrease in the manifestations of diarrhea syndrome in calves of the experimental group in the first decade of life compared with the control by 25,0%, and its duration by 35,7%. The obtained research results were processed using the Microsoft Excel 2010 computer program using Student's criterion. The results were considered significant from p≤0.05.
