Abstract: The most accessible method for assessing animal's energy and protein supply is to determine the content of urea, protein in milk and the ratio of urea to protein. The research results showed that out of 19 studies it is only highly productive animals that have an optimal supply of energy and protein. The main problem on these farms is the shortage of available energy. 21.0% of animals have energy deficiency in their diets, 21% have energy and protein deficiency, 36% have energy deficiency and excess protein, and 5% have excess protein. One of the ways to solve this problem is to use protected fat to adjust the diet of animals. During the research, a feed fat additive was developed, which is a calcium salt of fatty acids obtained from the oil extraction industry waste (fuza), stabilized with the domestic antioxidant drug selenopyran. In a scientific and production experiment on sheep of the Tsigai breed, a significant increase in the weight of young animals by 7.0% was found, which received 1% of the mass of mixed feed from a high-energy feed additive relative to the control with the basic diet. The concentration of total cholesterol in the blood serum of lambs of the first experimental group was statistically significantly lower relative to the same indicator of the control group and in the second experimental group, where the animals received an increased level of feed additive. The results of scientific research indicate that the high-energy feed additive we have developed based on protected fat and selenopyran had a positive effect on the biochemical status of the animal body and allows to increase productivity.
