Abstract: Provided herein are methods for treating an animal using a composition that includes active IGF. The methods include treating an animal at risk of having an infection caused by an infectious agent, treating an animal having an infection, and treating a symptom associated with an infection. In one embodiment, the infectious agent is a virus. In one embodiment, the administering includes daily administration of at least 0.05 nanograms of active IGF-1 per kilogram bodyweight of the animal daily (ng/kg), at least 0.1 ng/kg, at least 2 ng/kg, at least 5 ng/kg, or at least 10 ng/kg.

Abstract: Provided herein are methods for altering a characteristic of an offspring or a litter. The method can include administering an effective amount of a composition that includes active IGF-1 to a pregnant animal, wherein a characteristic of an offspring of the pregnant animal is altered compared to a control offspring. In another embodiment, the animal is a lactating animal, wherein a characteristic of an offspring nursed by the lactating animal is altered compared to a control offspring. Examples of characteristics that can be altered include increased survival of offspring before weaning, increased weight of offspring at weaning, increased weight of offspring at end of growing phase, increased average daily gain, and increased average daily food intake. In another embodiment, a characteristic of a litter can be altered, such as increased number of offspring born alive, increased litter birth weight, increased offspring birth weight, reduced number of stillborn offspring, or a combination thereof.

Abstract: Feeding a diet supplemented with DDGS or another supplement containing UFA at a level above a threshold to animals such as swine, cattle, and poultry can have negative effects on carcass fat, certain growth parameters, and meat characteristics. However, if this diet is provided with a second supplement that contains CPFA at specified levels in the diet, the negative effects otherwise expected are wholly or at least partially countered. The invention recommends employing a supplemental source of CPFA between about 0.001% and about 0.5% of the diet by weight. Negative effects on carcass characteristics caused by ractopamine can also be countered by the addition of this amount of at least one source of CPFA in the diet.
