Влияние селеносодержащей добавки Сел-Плекс на эффективность откорма и мясную продуктивность бычков красно-степной породы

In the context of the Kabardino-Balkaria Republic, where the use of feed rations in their own production, there is a lack of standardized animal minerals. In connection with this development and scientific justification for biotechnical process model of 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 terms of 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 functional properties boost immunity and reduce the risk of disease in human’s range of diseases. Probiotics and microbial additives that are used in animal husbandry stimulate digestion and nutrient digestibility of forage in the diet, thereby increasing productivity and animals. Feed additive Sel-Plex (organic selenium) manufactured by Alltech (USA). The article presents the results of efficacy of the drug Sel-Plex (selenium) for fattening steers red-steppe breed. When this positive action is detected in animals in 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 the experimental 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 experimental group is more than 14.25 %. Revenue additional increase of one head of the experimental group was 1460 rubles, and profitability up 14.25 % compared to the control.
