Abstract

The article is devoted to the current world problem of vegetable protein deficiency, the solution of which can be white lupine. Particular attention is paid to assessing the bioavailability of nutrients from white lupine (Lupinus albus) in the body of non-human primates M. Mulatta. Because primates are phylogenetically closer to humans than other laboratory animals, which is very convenient for modeling and studying the digestibility of nutrients in diets. The purpose of the article is to study the digestibility of nutrients in lupine in the structure of complete feed and its effect on the biochemical parameters of the blood. As a result of the research, it was found that the inclusion of white lupine in the structure of the diet allows to improve the bioavailability of nutrients of complete feed, when included in the structure of the diet of white lupine in an amount of 10%, it made it possible to improve the digestibility of crude protein in relation to the control group by 5.5%, crude fat by 0.99%, crude fiber by 1.84%, BEV by 7.99%, crude ash by 4.67%, calcium (Ca) and phosphorus (P) by 6.99%, and 1.02 %. With the inclusion of 20% white lupine in the structure of the diet, it made it possible to improve the digestibility of crude protein in relation to the control group by 9.28%, crude fat by 6.5%, crude fiber by 5.98%, BEV by 2, 78%, crude ash by 11.28%, and absorption of calcium (Ca) and phosphorus (P) by 9.93% and 8.68%. At the same time, the results of hematological analyzes generally indicate the safety of consuming white lupine for 35 days.
