METHOD OF APPLICATION OF FEED ADDITIVE FOR PIGS

摘要

FIELD: agriculture.;SUBSTANCE: method of application of feed additive for pigs, comprising lactic ferment based on consortium of live lactic acid and propionic acid bacteria of three complexes: the 1^st of strains of lactic acid bacteria S. salivarius-LT-1, S. Thermophilus-LT9, LT10, LT11 and strain of propionic acid bacteria Propionibacterium freidenreichii-LT8 in the ratio of 1:3; 2^nd of strains of lactic acid bacteria L. Plantarum-LT7, L. Acidophilus-LT12 and strain of propionic acid bacteria Propionibacterium freidenreichii-LT8 in the ratio of 2:1; 3^rd of the strains of propionic acid bacteria Propionibacterium freidenreichii-LT8 and lactic acid bacteria S. salivarius-LT-1, L. Plantarum-LT7, S. Thermophilus-LT9, LT10, LT11, L. Acidophilus-LT12 in a ratio of 7:2, which is then used for fermenting pasteurized milk with fat content of 1.5-2.5% and a ratio of 1:30, and the additive is daily fed together with the combined feed, in addition the minerals are periodically added to the composition of the feed additive: potassium iodide - KI and sodium selenite - Na₂SeO₃, adding is carried out after every day of omission, alternating with potassium iodide and sodium selenite weekly during the fattening period, starting with the four months of age of the piglets, and potassium iodide is added in an amount of 0.46 mg and sodium selenite - in an amount of 0.44 mg, i.e. 0.2 mg of pure selenium, per 1 kg of dry matter of diet.;EFFECT: increase in live body weight due to increase in muscle tissue, improving the quality of meat by reducing the layer of subcutaneous fat, increase in total body resistance to diseases of pigs.;8 tbl, 2 ex
