Abstract
This disclosure relates generally to a microbial treatment for poultry. More particularly, the disclosure relates to a direct fed microbial composition including one or more lactic acid bacteria strains in combination with one or more Bacillus bacteria strains configured to inhibit gastrointestinal pathogens in a bird. A method of use is also disclosed herein.
Claims6
A method of improving bird performance, comprising:
- introducing into the gastrointestinal tract of one or more birds on the day-of hatch an effective amount of the direct fed microbial composition comprising at least one Bacillus strain and at least one Lactobacillus strain;
- wherein the at least one Lactobacillus strain is chosen from at least one of strains Lactobacillus plantarum Lp-115 and Lactobacillus salivarius Ls-33;
- and the at least one Bacillus strain is chosen from at least one of strains Bacillus subtilis 747 deposited as NRRL B-67257, Bacillus subtilis 967, Bacillus subtilis 1104 deposited as NRRL B-67258, Bacillus subtilis 1145, Bacillus subtilis 1541 deposited as NRRL B-67260, Bacillus subtilis 1781 deposited as NRRL B-67259, Bacillus subtilis 1999 deposited as NRRL B-67318, and Bacillus subtilis 2018 deposited as NRRL B-67261;
- wherein the ratio of the at least one Lactobacillus strain to the at least one Bacillus strain in said direct fed microbial composition is at least about 4:1;
- wherein the effective amount of said direct fed microbial composition comprises a concentration of the isolated Bacillus strain of between about 2.5×107 CFU/bird and about 1.0×109 CFU/bird and a concentration of the isolated Lactobacillus strain of between about 2.5×107 CFU/bird and about 1.0×109 CFU/bird;
- and wherein the introduction of the direct fed microbial composition provides at least one benefit chosen from:
- inhibiting a pathogen chosen from at least one of Escherichia coli, Clostridium perfringens and Enterobacteriaceae in the one or more birds;
- decreasing a mortality rate of the one or more birds;
- improving the coefficient of variation of weight of the one or more birds;
- reducing the occurrence of necrotic enteritis in the one or more birds;
- reducing the occurrence of colibacillosis in the one or more birds;
- and
- modulating immune responses of inflammatory cytokines in gastrointestinal epithelial cells in the one or more birds.
