The new-developed fodder concentrate containing vegetable (legume and sunflower) protein and intended for replacement in fish flour and other additives of animal origin in compound feed compositions have been under study. The concentrate composition (%): full fat extruded soybean (45), extruded lupine (18.5), Protemil (30%), amino acids (5.3%), linseed oil (0.3). Expensive fish oil is replaced with linseed oil that contains more of unsaturated linolenic acid. Dosage of iodine and selenium bioplexes as well as B12, that is absent in plant raw material, are increased in the concentrate. Two groups of fattened pigs were under study. In intestines the animals fed with a protein concentrate, positive representatives of normal microflora dominated. 1 g of faeces contained 10E9 microbial cells (CFU) of bifidobacteria, and 10E8 CFU of lactobacilli. Metabolism in piglets of the experimental group was more intensive. The hemoglobin content was higher, and the blood color index exceeded that of the control group by 0.17 (Р less 0.001). Daily average body weight gains in both groups of animals were of 698-708 g. Feed conversion efficiency at the use a new protein concentrate was by 2.3% low. Application of compound feed containing the new concentrate was economically effective; the new feed is cheaper by 7.2-7.11%.
