Popis: The article discusses the results of studying the use of feed additives with a high degree of protein protection in feeding highly productive cows. These feed additives have fairly stable characteristics, contain a high volume of protected protein PassPro Soy - 69.33% and PassPro Balance 70.80%, respectively, have a high digestibility of organic matter PassPro Soy - 90.38% and PassPro Balance 86.57%. An increase in the milk productivity of cows by 8.4 and 5.1%, the amount of milk fat by 10.8 and 6.1%, and milk protein by 9.9 and 6.1% was established. An improvement in the physiological and biochemical status of cows in the experimental groups was established. Dry matter consumption increased by 3.3 and 1.2%. Profits from milk sales increased by 11.6% and 8.4%.
