METHOD OF PRODUCTIVITY INCREASING AND OFFSPRING PRESERVATION IN PIG BREEDING (OPTIONS) Russian patent published in 2018 - IPC A23K50/30 A23K10/18 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture, in particular to fodder production. Method comprises daily administering a feed supplement in the form of a filler and a preparation with probiotic activity to the compound feed. As a preparation with probiotic activity two strains are used: a strain of Enterococcus faecium 1-35 bacteria and a strain of Bacillus megaterium B-4801 bacteria, which dried biomass in mixture in equal amounts is applied onto the filler in the form of calcined diatomite chips containing of 2.2×10⁸ CFU Enterococcus faecium 1-35 living bacteria and 2.1×10⁸ CFU of Bacillus megaterium B-4801 living bacteria per 1 g of feed additive. Feed additive is given once a day to the weaning and fattening group piglets during the entire piglets weaning and fattening period. Second variant of the method includes the daily administration of a feed additive in the form of a filler and a preparation with probiotic activity to the compound feed. As a preparation with probiotic activity two strains are used: a strain of Enterococcus faecium 1-35 bacteria and a strain of Bacillus megaterium B-4801 bacteria, which dried biomass in mixture in equal amounts is applied onto the filler in the form of tripolite containing of 1.3×10⁸ CFU Enterococcus faecium 1-35 living bacteria and 3.3×10⁸ CFU of Bacillus megaterium B-4801 living bacteria per 1 g of feed additive. Feed additive is given once a day to pregnant breeding pigs before farrowing for 10 days. Then continue to give to the milking sows for 30 days before the piglets weaning.

EFFECT: implementation of a group of inventions ensures an increase in the digestibility and digestibility of nutrients in rations and the improvement of the grown offspring zootechnical indicators.
