IMPROVING THE PRODUCTIVE, PHYSIOLOGICAL AND BIOCHEMICAL INDEXES OF YOUNG PIGS WHEN USING MULTIENZYME COMPLEXES AND PROBIOTIC IN FEEDING
Solving the problem of increasing the profitability of pig farms, the experts pay attention to the costs associated with the preparation or purchase of feed. Thus variants to reduce the cost of feed units without a substantial reduction in productive activities are discussed. The possibility of using feed from own cheaper grain (wheat, barley, bran, etc.) is most preferred, however, these foods contain a lot of non-starch polysaccharides (NSP) that are not digested in the digestive tract of monogastric animals, moreover, interfere with the absorption of other feed nutrients. Solving this problem, zootechnical science has developed a range of forage preparations, allowing it to split up non-starch polysaccharides in the gastrointestinal tract of pigs and to expand the possibility of using grain when rationing diets for different groups of pigs. These feed drugs include, primarily, the enzymes of biological and chemical origin. Recently it becomes possible to use immunobiological preparations - probiotics during rearing pigs to increase nonspecific resistance of the organism, when disturbing the normal processes of digestion associated primarily with enzymatic deficiency. From the above, the purpose of the research was the study of various biologically active additives in feed mixtures and fodders fed to young pigs and a method of increasing their productive indexes and quality of their products by optimizing use of energy and nutrients of diets, which are based on crops of local production. Studies have shown that the combined use of enzyme preparations with probiotic feed additive in the diet has a positive effect on physiological, biochemical and productive indexes of fattening pigs.
