Methods and compositions for control of coccidiosis
Feeding yeast cell wall-containing compositions, including those compositions comprising mannanoligosaccharide(s), to animals exposed to or infected with coccidia, especially poultry exposed to pathogenic species of Eimeria, results in improved livestock performance and physical condition as compared with those animals who were not fed such compositions.
1. A method for reducing coccidial infection in an animal suffering from or exposed to coccidial infection, said method comprising the step of feeding to said animal an amount of a composition comprising yeast cell walls and at least one yeast-derived mannanoligosacoharide effective for reducing coccidial infection;
wherein the method further includes the step of monitoring the animal for the presence of coccidial infection or for cecal lesions before or after the step of feeding said composition.
2. The method of claim 1 , whereby said composition is admixed with a feed ration prior to feeding to said animal.
3. The method of claim 1 , whereby said composition is fed to an animal as a dietary supplement.
4. The method of claim 2 , wherein the composition comprising yeast cell walls is fed to the animal in an amount providing from about 0.5 to about 20 kg of yeast cell wall per tonne of feed.
5. The method of claim 1 , wherein said mannanoligosaccharide-containing composition is formulated for feeding to bovine, porcine, avian, equine, ovine, lapine, and caprine species.
6. The method of claim 1 wherein said composition is derived from a species selected from the group consisting of Saccharomyces, Candida, Kluyveromyces and Torulaspora.
7. The method of claim 6 wherein said composition is derived from Saccharomyces cerevisiae.
8. The method of claim 7 wherein the composition is derived from Saccharomyces cerevisiae strain NCYC 1025.
9. The method of claim 1 wherein the composition comprises dried cells of yeast.
10. The method of claim 1 wherein the composition further comprises mannanoligosaccharide.
11. The method of claim 5 wherein the animal is a porcine or an avian species.
12. The method of claim 11 wherein the avian species is a chicken, turkey, duck, goose, pheasant, quail or a companion bird.
13. The method of claim 1 wherein the composition further comprises at least one anticoccidial ionophore.
14. The method of claim 1 wherein the composition further comprises at least one anticoccidial steroidal sapogenin.
