Abstract

Scientific and economic experience on the effectiveness of feeding different forms and levels of selenium was carried out on suckling pigs of a large white breed, formed on the principle of analogues in three groups of 30 heads, each 60 days long. The suckling sows were together with the piglets for 28 days (before weaning the pigs) and received compound feed SK-2 according to the feeding scheme adopted at the enterprise. Suckling piglets were fed CK-3 before weaning, and CK-3 and CK-4 after the detachable (29-60 days). Piglets of the 2 nd and 3rd experimental groups received 0.15 and 0.20 mg of B-Traxim Selenium per 1 kg of compound feed. Piglets of the control group were fed in the composition of SC-3 and SC-4 inorganic selenium (sodium selenite) in an amount of 0.3 mg per 1 kg of feed, whereas the young of the 2nd and 3 experimental groups received 0.15 and 0.20 mg V-Traxim Selene. The use of growing pigs of various levels of B-Traxim Selenium as part of mixed feeds by 1 kg contributed to an increase in the average daily increase in the intensity of the increase in live weight of the young at 28 and 60 days of age, respectively 2.8; 2.4; 3.1; 2.7% and 6.2; 3.6; 14.0; 11.4% compared with control animals. The feeding of different levels of B-Traxim Selenium contributed to the reduction in the cost of ECE by 6.95-4.23%, crude protein 6.7-3.9% and feed 6.7-3.8%. Inclusion in the diet of the experimental groups of piglets of various levels of B-Traxim Selenium contributed to an increase in the digestibility of all nutrients compared to the control. The use of different levels of B-Traxim Selenium in the diets of rearing young pigs contributed to an increase in the content of morphological, biochemical, and immunological blood parameters. The greatest economic effect was obtained in the 2 nd experimental group of piglets who received 0.15 mg of B-Traxim Selenium per 1 kg of feed and amounted to 340 rubles per head.
