Abstract
Compositions for preventing or decreasing cryptosporidiosis include sources of hydrogen peroxide and are fed to animals. The animals may be neonatal calves and the cryptosporidiosis may be caused by Cryptosporidium parvum. Methods of preventing or decreasing cryptosporidiosis in animals by feeding the hydrogen peroxide-generating compositions to the animals are also disclosed. Some disclosed methods reduce the number of Cryptosporidium oocysts shed by an infected animal or reduce the infectivity of Cryptosporidium oocysts shed by an infected animal. Some methods include feeding the hydrogen peroxide-generating compositions to animals ultimately afflicted with cryptosporidiosis, and the animals gain weight despite the infection.
Claims19
A method of feeding a calf susceptible to infection with Cryptosporidium parvum, the method comprising:
- providing a liquid feed to the calf, the liquid feed comprising:
- a hydrogen peroxide-generating composition admixed with the liquid feed, the composition including a source of hydrogen peroxide selected from sodium percarbonate and glucose oxidase with dextrose, wherein the source of hydrogen peroxide is provided at about 0.07 wt % to about 3.00 wt % of the liquid feed on a dry basis,
- wherein the Cryptosporidium parvum infection is prevented or reduced in the calf if the calf is exposed to Cryptosporidium parvum.
A method of feeding a livestock animal susceptible to contracting cryptosporidiosis, the method comprising:
- providing a feed to the livestock animal, the feed comprising:
- a hydrogen peroxide-generating composition admixed with the feed, the composition including a source of hydrogen peroxide selected from sodium percarbonate and glucose oxidase with dextrose, wherein the source of hydrogen peroxide is provided at about 0.07 wt % to about 3.00 wt % of the feed on a dry basis,
- wherein contracting cryptosporidiosis is prevented or reduced in the animal if the animal is exposed to Cryptosporidium spp.
