1. Dry microbial silicon-containing feed additive for farm animals and birds, characterized by the fact that it consists of viable cells and spores of the Paenibacillus polymyxa strain VSGUTU-1 no more than 2×10 9 CFU/g, residues of a nutrient medium containing bentonite as a source of silicon in an amount of 2-3% and wheat bran up to 100%.

Description

The invention relates to feed production and can be used to produce feed additives that enrich animal bodies with mineral silicon, improve feed digestibility, and reduce feed costs. The proposed microbial silicon-containing feed additive is a suspension of the Paenibacillus polymyxa strain VSGUTU-1 culture and wheat bran as a filler (see RU No. 2784088, C12N 1/20, C12P 19/04, C12R 1/01, published November 23, 2022). On average, 1 kg of wheat bran contains: thiamine - 7.1 mg; riboflavin - 2.9 mg; niacin - 308 mg. Wheat bran protein is the most biologically complete, containing all the essential amino acids. A feed additive composition is known, consisting of several strains of Bacillus subtilis 3BP5 (NRRL B-50510), 918 (NRRL B-50508) and 1013 (NRRL B-50509), but does not contain any additional enzymes other than protease, which is subtilisin (see RU 2754276 C2, A23K 10/18, A23K 20/174, A23K 20/189, A23K 20/20, A23K 50/30, published on 31.08.2021). The disadvantage of the drug is that the composition contains several cultures of microorganisms and only one enzymatic activity is achieved. A probiotic feed additive for farm animals and birds is known, which includes spore-forming bacteria of the strains Bacillus subtilis TV-26 (VKPM B-11954) and Bacillus licheniformis B-020 (VKPM B-10995) (see RU 2654875 C2, A23K 10/18, published 05/23/2018). A disadvantage of the feed additive is the use of two strains of spore-forming bacteria, which complicates the technological process of its production. The enzyme preparation amylosubtilin is known, which is an evaporated filtrate of the culture fluid of Bacillussubtilis bacteria, possessing amylolytic and proteolytic activity, intended for use in animal husbandry as an additive to feed, compound feed and premixes (see SU No. 737442 A1, C12D 13/10, published 30.05.1980, GOST 23635-90 "Enzyme preparation amylosubtilin GZkh. Technical conditions"). A known drug is protosubtilin, obtained by drying the culture liquid of Bacillus subtilis producers in a spray dryer. It has proteolytic and slight amylolytic activity and is used as an additive to feed and in premixes (see SU No. 1442548A1, C12N 11/00, C12N 9/56, 07.12.1988). A well-known cellulolytic drug is celloviridin, which is formed by drying the evaporated filtrate of the culture fluid of the fungus Trichodermaviride, which is used in the feed industry as an enzyme supplement in the production of feed. A drug based on the filtrate of the micromycete Penicillium funiculosum is known, which contains a complex of enzymes with cellulase and glucanase activity. The preparation is recommended for use as a liquid feed additive and dry feed for farm animals (see RU No. 2261910 C2, A23K 1/165, A23K 1/18, A23K 3/03, C12N 1/14, C12N 1/15, C12N 1/19, C12N 1/21, C12N 5/10, C12N 9/16, C12N 9/18, C12N 9/24, C12N 9/42, C12N 11/18, C12N 15/09, C12R 1/80, published 10.10.2005). A significant drawback of known enzyme feed additives is that they do not contain the enzymes necessary for the prevention of gastrointestinal diseases in animals and poultry. The biological basis of the feed additive is known, based on the Paenibacillus ehimensis IB-739 strain. The feed additive can be used in feed production (see RU No. 2662931 C1, C12N 1/20, C12N 9/00, published July 31, 2018). Significant disadvantages of the known invention include the use of an adhesive - Na-CMC, which is reflected in the cost of the product and leads to an increase in the cost of the product. The closest method to the claimed invention in terms of the achieved technical result and set of features is a biologically active feed additive for animals and birds, in which diatomaceous earth crumbs are used as a silicon-containing material, with a diatomaceous earth crumb percentage of 95-99.854%, and Bacillus subtilis and Bacillus licheniformis are used as bacteria. In this production method, the silicon-containing material is pre-fired at a temperature of 600-700°C, then bacteria are sprayed onto the fired silicon-containing material, after which plant additives are applied to the resulting product (see RU 2663014 C1, A23K 20/20, A23K 20/28, A23K 40/10, A23K 50/70, published 01.08.2018). The disadvantage of the microorganism-based prototype is that it does not provide antimicrobial and enzymatic activity, and the multi-component nature of the preparations (a large number of strains in their composition) complicates the process of their production, which increases the cost of the feed additive. Thus, the technical objective of the invention is to develop a feed additive based on the use of silicate bacteria for farm animals in the main diet, which will solve the problems of using chemical and artificial additives in the feed base of farm animals and poultry. The technical result of the invention is achieved by using silicate microorganisms that are capable of assimilating forms of silicon that are inaccessible to the body in their metabolism.
