The results of studies on feeding biologically active additives suspensions of chlorella and Bactistatin in the diets of primates are presented. Its positive effect on the bioconversion of diets was experimentally established. The coefficients of digestibility of nutrients with dry chlorella and fishmeal in the composition of complete feed were determined. The obtained experimental data are important for the preparation of scientifically grounded and optimally balanced feeding rations, taking

This will optimally balance feed rations for all nutrients, while reducing feed costs and, as a result, increasing the profitability of keeping primates. It was found that the introduction of chlorella powder and fishmeal into the diet improves protein absorption by 6.83 and 5.66%, crude fat - by 2.61 and 3.92, crude fiber - by 4.78 and 4.25, NFES - by 4.15 and 2.26, crude ash - by 18.93 and 12.08%. The use of calcium and phosphorus macronutrients was higher in the 3rd experimental group, which received 14% chlorella in the main diet by 1.38 and 8.07%, respectively. In the 5th experimental group, which received 18.26% of the main ration of fishmeal, calcium was absorbed more efficiently by 4.77, and phosphorus - by 1.21%. The use of diet supplements in the form of a suspension of chlorella and Bactistatin helped to stimulate the bioconversion of nutrients in the diets used in the nursery for feeding monkeys, and enabled to maintain the main blood parameters within physiological norms.
