Abstract

The article is devoted to the current problem of providing rations with a source of protein with a high biological value. Such a source is suggested to be white lupine and products of its processing. Since, white lupine exceeds the protein content of peas, vetch and other legumes by more than 10%. And the significant content of fat in its composition allows, when using it, to reduce or completely abandon the use of sunflower oil in the diet. The use of white lupine allowed the experimental primates to use the food efficiently. The lowest costs were observed in the 3-test group. Energy costs were lower by 48.80%, crude protein by 47.22% and digestible protein by 51.3%. In the 2-experimental group, the costs of metabolic energy, crude protein and digestible protein were lower by 25.00%, 26.38% and 39.20, respectively. Thus, the inclusion of white lupine in the structure of the diet helps to improve the nutritional value of rations, to reduce the cost of nutrients and feed, improving the economic indicators of the maintenance of primates.
