Podcast: Effects and functions of copper on nutrient utilization in growing pigs.
Dr. Charmaine Espinosa, a post-doctoral research fellow in the Stein Monogastric Nutrition Lab, discusses the Effects and functions of copper on nutrient utilization in growing pigs. Adapted from a presentation at the Proc. 21th Annual Midwest Swine Nutrition Conf. Danville, IN, Sep. 8, 2022.

Research Report: Effect of increasing microbial phytase levels on digestibility of phosphorus in field peas fed to young pigs.
The majority of P in most plant feed ingredients is bound to phytate. Pigs, however, do not synthesize adequate endogenous phytate to release the P bound to phytate, which results in low digestibility of P in field peas. Values for ATTD and STTD of P in field peas without and with phytase have been reported, but there are no comparative values for the ATTD and STTD of P in field peas adding different levels of phytase. The objective of this experiment is to determine the effect of increasing levels of phytase on the apparent total tract digestibility (ATTD) and standardized total tract digestibility (STTD) of P in field peas fed to growing pigs.

Research Report: Digestibility of energy in ten sources of wheat middlings fed to growing pigs.
Data have been published for the composition of wheat middlings from flour mills in the U.S. and data for digestible energy (DE) and metabolizable energy (ME) have been reported as well. However, it is not known if the data obtained in wheat middlings from the U.S. also are representative for wheat middlings in Europe. Therefore, an experiment was conducted to test the null hypothesis that there are no differences in composition, apparent total tract digestibility (ATTD) of gross energy (GE), and concentration of DE and ME between wheat middlings sourced from flour mills in Europe and in the U.S.

Research Report: Determination of DE and ME in a new variety of soybeans fed to growing pigs
Soybean meal is the principal amino acid (AA) source in diets for pigs and it also supplies a considerable amount of metabolizable energy close to what is found in corn. However, new varieties that have different characteristics are sometimes developed and an example of such is the Photoseed variety of soybeans that captures more carbon and sunlight leading to a more nutrient rich ingredient and a reduced footprint from crop production. There is, however, no information about the nutritional value of the soybean meal produced from the Photoseed variety of soybeans. Therefore, the objective of this research was to test the hypothesis that the concentration of digestible energy (DE) and metabolizable energy (ME) are not different in soybean meal produced from Photoseed soybeans compared with control soybean meal when fed to pigs.
