ПРОДУКТИВНЫЙ ПОТЕНЦИАЛ ВЫРАЩИВАЕМОГО МОЛОДНЯКА СВИНЕЙ ПРИ ОБОГАЩЕНИИ РАЦИОНОВ РАЗЛИЧНЫМИ СОЕДИНЕНИЯМИ СЕЛЕНА

Abstract

To carry out scientific and economic experience, three groups of piglets-analogues at the age of 28 days (20 heads in each group) were selected, depending on the origin and live weight. The duration of the experiment was (62 days). According to the experimental scheme, the growing young pigs of the 1st control group as part of the SK-4 compound feed received 0.30 mg/kg of inorganic selenium feed in the form of sodium selenite, analogues from the 2nd and 3rd experimental groups received the same compound feed with the addition of 0.15 and 0.20 mg/kg of organic selenium, respectively. Feeding young pigs of the 2nd and 3rd experimental groups as part of the SK-4 compound feed of organic selenium in the amount of 0.15 and 0.20 mg/kg contributed to an increase in live weight and average daily gains at 60 and 90 days of age, respectively, by 7.46 g, 7.24 g and 12.3%, 12.1% and 8.4 g 8.3 g and 9.5%, 9.5% compared to control animals. The inclusion of various levels of organic selenium in the composition of the SK-4 compound feed contributed to an increase in the digestibility of all nutrients compared to the control. The inclusion of organic selenium in the growing young pigs of the experimental groups of 0.15 and 0.20 mg/kg of feed had a positive effect on the dynamics of morphological, biochemical, immunological parameters that cause an increase in the protective properties of the body. The greatest economic effect was obtained in the 2nd experimental group of piglets receiving 0.15 mg of B-Traxime Selenium per 1 kg of feed and amounted to 292.5 rubles per head.
