Abstract

Claims (19)

1. A method of inhibiting focal ulcerative dermatitis in poultry, the method comprising:

feeding poultry diagnosed with focal ulcerative dermatitis a feed product comprising a base feed and a direct-fed microbial composition in an amount effective to inhibit focal ulcerative dermatitis,

wherein the amount effective to inhibit focal ulcerative dermatitis ranges from about 25,000 CFUs per gram of base feed to about 1.5 million Colony Forming Units per gram of base feed, and

wherein the direct-fed microbial composition comprises two or more distinct strains of Bacillus pumilus.

2. The method of claim 1 , wherein the two or more distinct strains of Bacillus pumilus comprise two strains included in approximately equal amounts.

3. The method of claim 1 , wherein the feed product is fed to the poultry on a daily basis starting at a laying phase.

4. The method of claim 3 , wherein the laying phase begins when the poultry are between about 18 and about 22 weeks old.

11. A method of feeding cage-free poultry, the method comprising:

forming a feed composition by admixing a direct-fed microbial composition with a base feed at a direct-fed microbial inclusion rate of about 25,000 CFUs per gram of base feed to about 1.5 million CFUs per gram of base feed, wherein the direct-fed microbial composition contains two or more distinct strains of Bacillus pumilus;

feeding cage-free poultry diagnosed with focal ulcerative dermatitis the feed composition.

12. The method of claim 11 , wherein feeding the cage-free poultry reduces one or more symptoms of focal ulcerative dermatitis exhibited by the cage-free poultry.

13. The method of claim 11 , wherein the base feed comprises a complete poultry feed formulated to provide at least a majority of nutrients to the cage-free poultry.
