Abstract
A method of controlling foam in a manure pit. In the method, one or more Bacillus strain(s) is administered in an effective amount to animals whose manure is stored in the manure pit. Also provided is a method of controlling foam in a manure storage unit. In the method, one or more Bacillus strain(s) is administered in an effective amount to the manure storage unit.
Claims6
A method of controlling foam in a manure pit, the method comprising administering Bacillus strains in an effective amount to pigs whose manure is stored in the manure pit, the Bacillus strains comprising:
- B. licheniformis 842 (NRRL B-50516) or a strain having all of the identifying characteristics of the B. licheniformis 842 (NRRL B-50516);
- B. subtilis 27 (NRRL B-50105) or a strain having all of the identifying characteristics of the B. subtilis 27 (NRRL B-50105);
- and
- B. licheniformis 21 (NRRL B-50134) or a strain having all of the identifying characteristics of the B. licheniformis 21 (NRRL B-50134), wherein
- 70% of the total CFUs of the Bacillus strains is B. licheniformis 842 (NRRL B-50516) or a strain having all of the identifying characteristics of the B. licheniformis 842 (NRRL B-50516),
- 10% of the total CFUs of the Bacillus strains is B. subtilis 27 (NRRL B-50105) or a strain having all of the identifying characteristics of the B. subtilis 27 (NRRL B-50105), and
- 20% of the total CFUs of the Bacillus strains is B. licheniformis 21 (NRRL B-50134) or a strain having all of the identifying characteristics of the B. licheniformis 21 (NRRL B-50134), and
- wherein strains are administered at a rate of at least about 1.0×105 CFU per gram of feed fed to the pigs.
