Described herein are compositions and methods that involve use of omega-3 polyunsaturated fatty acids (e.g., fish oil and/or flax oil) as supplements to colostrum. When administered to newborn calves the combination of colostrum with fish oil and/or flax oil can improve the health and immune function of the calf.

The present invention concerns a composition containing medium-chain fatty acids or salts or mono-, di-, triglycerides, esters or amide derivatives of medium-chain fatty acids. In a further aspect, the present invention concerns also a feed, supplemented with the composition, and a method for feeding animals, in particular calves, cattle and dairy cattle.

The present invention relates to a Bacillus amyloliquefaciens K2G strain, which is excellent in removal of anti-nutritional factors and in protease activity, and shows excellent antimicrobial activity against pathogens and reduced productivity of viscous substances, a method for producing a fermented soybean meal using the strain, a fermented soybean meal produced therefrom, and a feed composition including the same. The fermented soybean meal prepared by Bacillus amyloliquefaciens K2G strain according to the present invention has few anti-nutritional factors such as trypsin inhibitors, soybean oligosaccharides, and polysaccharides, a high content of crude proteins, and high protein solubility, and also consists of small-sized peptides digestible by livestock due to low-molecularization, thereby being effectively used as a high-quality vegetable protein feed having excellent absorption rate and feed efficiency.

The invention relates to production of a yeast strain with increased mannan oligosaccharides, amino acids, and complex carbohydrates. The invention further relates to the process to propagate and ferment such yeast. The invention further relates to methods of use of the yeast as a feed additive for animals and a food product for humans.

The present invention relates to a composition for ameliorating viral infections in nursery pigs. The composition contains the polyether ionophore narasin, and is supplied to the nursery pigs in an orally-acceptable form. The composition is effective in reducing viral shedding and the severity of diarrhea after challenge of nursery pigs with Porcine Epidemic Diarrhea Virus (PEDV).

There is provided an exemplary method of treating weaning piglets to induce weight gain, or to prevent a reduction in rate of weight gain, the method comprising exposing the weaning piglets to a rabbit maternal pheromone having an interomone effect. In an exemplary embodiment, the rabbit maternal pheromone is trans-2-methyl-2-butenal. The method may include the step of applying the rabbit maternal pheromone to a feeder for the weaning piglets. Moreover, the rabbit maternal pheromone may be applied to a feeder (or to the feed) for the weaning piglets at least once during a first week of weaning. Further, the method may include weighing the weaning piglets at intervals to determine a rate of weight gain, and measuring an amount of feed consumed by the weaning piglets to calculate the amount of weight gained per unit of feed consumed.
