Nonruminant Nutrition: Dietary Supplements and Additives.

The article presents abstracts of various research papers related to animal nutrition that were presented during the symposium held on July 25, 2005 in Cincinnati, Ohio, which was organized by the American Dairy Science Association, the American Society of Animal Science, and the Canadian Society of Animal Science. In one of the papers titled " Effects of Bio-Mos and Carbadox on Gastrointestinal pH, Organ Weight and Morphology of Nursery Pigs," a 3-week experiment was conducted to evaluate the effect of a mannan oligosaccharide product and antibiotic on gastrointestinal characteristics of pigs. Thirty pigs were weaned at an average of 21.2 d and 5.95 kg BW. At weaning, six pigs were euthanized for gastrointestinal sample collection, while the remaining 24 pigs were randomly allocated to one of four dietary treatments. The experiment was conducted as a 2 x 2 factorial arrangement, with the factors being 0 or 0.2% Bio-Mos and 0 or 55 ppm carbadox. Twelve pigs, representing three pigs per treatment, were euthanized on each of 2 days, 7 or 21 d post-wean.
