Abstract: Compositions for reducing the emission of methane by ruminant animals are disclosed. The compositions include avian antibodies against methanogens generally found in the rumen of the animals. Egg contents of eggs from female birds inoculated with immunogenic compositions containing one or more methanogens or antigens derived from methanogens are used. The antibodies in the egg contents may be used directly without further purification, may be partially purified or purified. The compositions may be administered in drinking water or in animal feed. Administering of the anti-methanogenic composition reduces the emission of methane and increases the efficiency of feed conversion.

Abstract: Neutralizing antibodies through recombinant protein expression were identified by mining antibody repertoires by high-throughput second generation sequencing. Sequencing across the majority of light and heavy chain variable regions of chicken immunoglobulins was performed at two immunological time points: a non-immune (naive) state and a post-hyperimmunization state. The mRNA was extracted from unsorted and unselected PBMC populations and identification of antigen-specific antibody sequences leveraged the significant disparity of abundance of an individual B cell clone in non-immune and immunized states. Through bioinformatic analysis, candidate amino acid sequences for variable heavy chain and light chains were identified. Recombinant polypeptides with the binding domains having the identified amino acid sequences for variable heavy chain and light chains were expressed and screened using immunoassays to confirm antigen-specificity.

Abstract: Compositions are described that include colostrum and/or milk replacer combined with pathogen specific avian antibodies. These pathogen specific avian antibodies include antibodies against pathogens causing infections and disease in the digestive tract as well as outside the digestive tract. Feeding regimens and methods for administering the colostrum and/or milk replacer with the pathogen specific avian antibodies result in the presence of IgY antibodies in the serum of a neonatal animal. The IgY antibody in the serum can neutralize pathogens causing infections outside of the digestive tract.

Abstract: A microbial adherence inhibitor in the form of fowl egg antibodies is disclosed, along with the method of making it and methods of using it. The inhibitor functions by substantially preventing the attachment of adherence of colony-forming immunogens in the respiratory tracts of host animals and humans. The inhibitor is made by inoculating female birds with the immunogen, harvesting the eggs which contain antibodies to the immunogen, and separating the yolk and albumin from the shells of the eggs. The yolk and albumin contents are administered to animals or human by distributing the contents directly or introducing the contents entrained in air.

The adherence inhibiting material can be formulated for use in a variety of ways such as an oral spray or a nasal spray. These formulations can be effective to prevent or reduce respiratory illnesses in animals and humans.

Abstract: The present disclosure relates to methods and compositions administered to the lymphatic tissue of an animal to prevent or reduce the incidence of disease or disease symptoms caused by one or more disease causing entities. Tonsillar compositions can be administered to the lymphatic tissue in the oral/nasal region of the animal and can include avian antibodies from eggs of hens inoculated with one or more target disease causing entities. Treating the lymphatic tissue in the oral/nasal region with the compositions described herein can reduce or prevent the disease causing entities from adhering to the lymphatic tissue resulting in reduced infection rates. The present disclosure also relates to oral compositions that can be used to reduce or eliminate oral pathogens in animals.

Abstract: Anti-toxin compositions are described that include avian antibodies against bacterial toxins. Administration of the anti-toxin compositions binds and neutralizes the bacterial toxin in the animals. Methods of making the anti-toxin compositions against the bacterial toxins are also described. The anti-toxin compositions can be effective against pathogenic bacteria and also to decrease the amount of bacterial toxins in the individual, especially in the GI tract. The anti-toxin compositions can also act as anti-inflammatory agents.

Abstract: A microbial adherence inhibitor specific to lactic acid producing microorganisms, in the form of fowl egg antibodies is disclosed, along with the method of making it and methods of using it. The inhibitor functions by substantially preventing the attachment or adherence of colony-forming immunogens in the fermentators. The inhibitor is made by inoculating female birds with the immunogen, allowing time for an immune response in the female bird and then harvesting the eggs that contain antibodies to the immunogen. The egg contents can be dried or used as a liquid and added to the media in the fermentators. Dependent upon the particular immunogen with which the female bird is inoculated, the egg antibody will specifically bind to the specific immunogen. When bacteria such as Lactobacillus spp. infect fermentation systems, they will further reduce alcohol conversion efficiency. Colony forming immunogens such as Lactobacillus spp.

Abstract: A microbial adherence inhibitor in the form of fowl egg antibodies is disclosed, along with the method of making it and methods of using it. The inhibitor functions by substantially preventing the attachment or adherence of colony-forming immunogens in the rumen and intestinal tracts of host food animals. The use of antibodies against Fusobacterium necrophorum adherence antigens decreases the colonization of F. necrophorum sufficiently to reduce or eliminate the incidence of liver abscesses in the animals.

Abstract: A method for the production of antibodies or microbial adherents administers is disclosed. The antibodies or microbial adherents inhibitors are administered to a patient suffering from strep throat to substantially prevent the adherents of colony-forming immunogens or haptens in the throat of the patient. Application of the antibodies should decrease the colonization of the oropharnyx, and therefore decrease symptoms of the sore inflamed throat and ultimately decrease the need for antibiotics.
