EFFECT OF ADDITIVES SELENIUM SEL-PLEX ON FEED EFFICIENCY AND MEAT PRODUCING RED BULLS-STEPPE BREED
In the context of the Kabardino-Balkaria Republic, where the use of feed rations in their own production, there is a lackof standardized animal minerals. In connection with this development and scientific justification for biotechnical process modelof intensive cultivation and fattening of young cattle up to 400–450 kg, provides high-quality beef has gained much importance.As is known from the literature, meat selenium enrichment refers to the most urgent and promising areas of research, in termsof ensuring the full and healthy eating people. Preparations with organic forms of selenium (Sel-Plex), the most acceptable,but not well understood in different programs rising and fattening cattle to produce selenium-enriched beef having functionalproperties boost immunity and reduce the risk of disease in human’s range of diseases. Probiotics and microbial additives thatare used in animal husbandry stimulate digestion and nutrient digestibility of forage in the diet, thereby increasing productivityand animals. Feed additive Sel-Plex (organic selenium) manufactured by Alltech (USA). The article presents the results ofefficacy of the drug Sel-Plex (selenium) for fattening steers red-steppe breed. When this positive action is detected in animalsin a dose of 0.35 mg per 1 kg of dry feed (1 time per day in the morning for 1 head) allows increasing live weight gain of theexperimental group by 16.1 % more than in the control. Feed consumption per 1 kg increase in the control group was 12.8 f. e.,and in the experimental group — on 2 f. e. less. Economic efficiency in the control group fattening was 4.8 % and the experimentalgroup is more than 14.25 %. Revenue additional increase of one head of the experimental group was 1460 rubles, andprofitability up 14.25 % compared to the control.
