Liquid diets fed hourly to pigs weaned at 19 days of age and exposed to rotavirus (weanling diarrhea).
Five diets were tested for their capacity to promote weight gains in newly-weaned, 19-d-old, rotavirus-exposed pigs. The diets were tested under conditions designed to minimize the stress of weaning. That is, rotavirus-exposed pigs were moved at weaning to an isolation unit, caged individually and fed hourly liquid diets that were high (approximately 26%) and low in protein (approximately 11%). In all experiments, pigs experienced postweaning rotavirus-associated diarrhea and depression in rate of gain. Pigs grew faster: when fed diets high in protein (approximately 26% protein) vs low in protein (approximately 11% protein) and when fed diets containing cows' milk proteins vs proteins from soybean flour. A diet containing antibodies to rotavirus did not ameliorate the weanling diarrhea.
