  • Patent number: 12599628
    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.

  • Publication number: 20250261666
    Abstract: The present disclosure describes animal feed products formulated to inhibit focal ulcerative dermatitis, and methods of feeding such products to the animals. Feeding methods involve providing poultry with a feed product that includes a base feed and a direct-fed microbial composition. The direct-fed microbial composition includes one or more strains of Bacillus pumilus. The poultry can include cage-free layer hens at risk of developing, or already diagnosed with, focal ulcerative dermatitis. Inhibition of focal ulcerative dermatitis can increase the egg production of the layer hens relative to layer hens fed the same base feed but lacking the direct-fed microbial composition.

  • Publication number: 20200305461
    Abstract: Methods involve feeding livestock animals, such as young poultry or calves, a feed product comprising a bacteriophage composition. The bacteriophage composition is configured to preserve the feed product and may exhibit lytic activity specific to one or more species of pathogenic bacteria, such as Salmonella, Escherichia, Campylobacter and/or Clostridium, which may be contaminating the feed product. The bacteriophage composition can remain in an inactive form until ingested by the animals, for example by including a protective outer coating, which may be comprised of digestible fat.
