MILK YIELD AND QUALITATIVE INDICATORS OF COLOSTRUM OF FIRST-CHIFFER COWS WITH THE BACKGROUND OF THE APPLICATION OF TISSUE BIOGENIC STIMULATES

The article presents the results of an experiment, the purpose of which was to study the milk yield and quality indicators of colostrum of first-calf cows against the background of the use of a tissue biogenic stimulator. The experiment was carried out in 2022 in the production conditions of JSC Uchkhoz Prigorodnoye. We have established that four-time administration of a tissue biogenic stimulator at a dose of 30 ml/animal. heifers 55-60 days before expected calving contributed to an increase in colostrum milk yield in the first day after calving by 8,6 (p˂0.001). There was an increase in protein content in colostrum by 1.2% (p˂0.05), immunoglobulins by 17.3% (p˂0.05), SOMO by 27.5% (p˂0.05), density by 2 .4% (p˂0.05).
