Physiological and immunological parameters of calves when stimulating mothers with the immunomodulator azoxivet in combination with sinestrol 2 %

The aim of the study was to research the effect of Azoxivet in combination with Sinestrol 2 % on the development of calf resistance. The experiment was carried out in the Dalnekonstanti-novsky district of the Nizhny Novgorod region. To assess the effectiveness of the experiment, the first portion of colostrum was analyzed for Ig concentration, and to analyze the development of calf resistance, immunological, morphological and biochemical analyzes of the venous blood obtained before drinking the first portion of colostrum, one hour after drinking, the next day, on the 7th, 14th and days of life were performed. As a result, an increase in the fraction of y-globulins in the blood of calves was recorded as early as an hour after drinking colostrum, and the peak of the indicator fell on the daily age. In addition, there was an active increase in the immunological parameters of calves.
