Research report: Effects of microbial phytase on the apparent and standardized total tract digestibility of calcium in milk co-products fed to growing pigs

Milk co-products are used in pig diets to provide lactose and, in some cases, high quality protein. In addition, milk co-products also provide calcium to the diets. However, this calcium can potentially bind to the phytate contained in the plant ingredients in the diets, which would reduce its digestibility.

The inclusion of microbial phytase in diets fed to pigs frees calcium that is bound to phytate. An experiment was conducted to determine if the apparent total tract digestibility (ATTD) and the standardized (STTD) total tract digestibility of calcium in milk co-products is improved when microbial phytase is added to the diets.

Podcast: Amino acid digestibility in dairy proteins compared with plant proteins

John Mathai, a Ph. D. candidate in the Stein Monogastric Nutrition Laboratory, looks at amino acid content and digestibility in in four protein products derived from milk, and compares them with protein ingredients derived from soy, peas, or wheat. Adapted from a presentation at the 2016 ASAS Midwestern Section meeting, Des Moines, IA, March 14-16.

Podcast: Effects of a novel phytase on growth performance and metacarpal bone ash in weanling pigs

Dr. Yanhong Liu, a former postdoctoral fellow in the Stein Monogastric Nutrition Laboratory, discusses her research into the effects of Cibenza Phytaverse G10, a a novel next-generation microbial phytase, on growth performance and metacarpal bone ash in weanling pigs. Adapted from a presentation at the 2016 ASAS Midwestern Section meeting, Des Moines, IA, March 14-16.

Press release: Production area does not affect phosphorus digestibility in soybean meal fed to pigs

URBANA, Ill. – Research at the University of Illinois is helping to determine the effect of growing conditions on the nutritional value of soybean meal. "The digestibility of phosphorus is the same in soybean meal grown in various regions in the United States,” says Hans Stein, professor of animal sciences at Illinois.

"The chemical composition of soybean meal is somewhat dependent on the area in which soybeans are grown, but it was not known if there are differences in the concentration of phytate among soybeans grown in different areas," Stein says. He and Kelly Sotak-Peper, then a doctoral candidate, set out to determine whether any differences existed.
