ABSTRACT

Problem statement. The health, productivity and reproductive functions of animals largely depend on the degree of contamination of feed with pathogenic microflora and toxins of various origins. Mycotoxins are fungal metabolites that may have deleterious effects in animals [1]. Mycotoxins are detected in cereal grains worldwide, with a prevalence of 88 % on feed and raw feedstus [2]. Mycotoxins routinely occur in common feedstuffs such as corn, corn silage, small grains and small grain silage, especially when growing conditions are sub-optimal. It should be noted that mycotoxins may or may not be present in moldy Toxicobiological effect of mycotoxins association of the Penicillium and Fusarium fungus (T-2 toxin at a concentration of 0.1 mg/kg, fumonisin B1 ‒ 0.5 mg/kg, vomitoxin (DON) ‒ 0.1 mg/kg, penicillic acid ‒ 1 mg/kg) was accompanied by the development of a complex pathological process in weaned piglets. In this regard, the detoxification and sorption capacity of the complex feed additive "Harufix+" based on mannanoligosaccharides was studied. The additive effect on the resorptive activity of mineral and vitamin nutrients of feed under the normal feeding conditions and in case of contamination with mycotoxins has been studied. The use of enterosorbent offset the toxic effects of micromycete metabolites, which contributed to the growth of piglets. Thus, weight growth rate increase of the piglets in group 1 (i.e., those whose diet included the additive, unlike the diet of the animals in control group) constituted 16 %, while their average weight growth rate was high and constituted 1.96 kg per day. In addition, during the study of calcium, phosphorus, magnesium, ferum, zinc, copper and manganese in the piglets blood was not found excretion of these elements with a sorbent, moreover, noted the normalization their blood level. The study content of vitamins A and E, the same as with mineral nutrients, has not been established decrease during treatment with study the pharmaceutical. The obtained results testify the active absorption in the gastrointestinal tract of the vitamin components within the fodder combined with fodder additive “Harufix+” and high biological accessibility of its transport forms. The efficiency of the additive can be explained by its composition, namely the complex of mineral and organic components that are formed by modification of the organic cations of the mineral surface.
