Effects of production area and microbial phytase on the apparent and standardized total tract digestibility of phosphorus by growing pigs

The area in which soybeans are grown is known to affect various aspects of the chemical composition of soybean meal produced from those soybeans. However, it is not known if there is a difference in the concentration of phytate, and therefore in phosphorus digestibility, among soybeans from different growing areas. Therefore, an experiment was conducted to determine the concentration of phytate and the apparent (ATTD) and standardized (STTD) total tract digestibility of phosphorus in soybean meal produced from soybeans grown in four different areas in the United States. A secondary objective was to determine the effect of microbial phytase on STTD of P in soybean meal from each of the four areas.

Podcast: Effects of phytase on phosphorus digestibility of rice co-products fed to growing pigs

Gloria Casas, a Ph. D. candidate in the Stein Monogastric Nutrition Lab, discusses the results of her research into the effects of phytase on phosphorus digestibility in brown rice, broken rice, full fat rice bran, defatted rice bran, and rice mill feed fed to growing pigs. Adapted from a presentation at the 2015 ASAS Midwestern Section meeting, Des Moines, IA, March 15-18.
