Dr. Charmaine Espinosa, a post-doctoral research fellow in the Stein Monogastric Nutrition Lab, discusses the results of a study conducted to test the hypothesis that supplementation of copper hydroxychloride at 150 mg/kg to diets improves growth performance by upregulating the mRNA transcription of genes involved in post-absorptive metabolism of lipids.

Dr. Charmaine Espinosa, a post-doctoral research fellow in the Stein Monogastric Nutrition Lab, discusses her research into the interactive effects of dietary copper and fiber on intestinal microbial protein concentration and digestibility of energy, crude protein, and fat by growing pigs fed diets containing distillers dried grains with solubles (DDGS).

Diego Rodriguez, a research specialist in the Stein Monogastric Nutrition Laboratory, presents the results of two experiments designed to compare digestibility of amino acids and concentrations of metabolizable and net energy in two soybean products: 1) soybean expeller produced using a high-shear dry extrusion process prior to pressing; and 2) conventional solvent-extracted soybean meal. Adapted from a presentation at the 2020 ASAS Midwestern Section meeting, Omaha, NE, March 2-4.

Vanessa Lagos, a Ph. D. candidate in the Stein Monogastric Nutrition Lab, discusses the results of her study that compared the digestible and metabolizable energy content of 23 sources of soybean meal from Argentina, Brazil, China, India, and the United States. Adapted from a presentation at the 6th EAAP International Symposium on Energy and Protein Metabolism and Nutrition, September 9–12, 2019 in Belo Horizonte, MG, Brazil.

Cristhiam Munoz, a recent Master's degree recipient, provides an update on the Stein Monogastric Nutrition Lab's calorimetric unit, which was designed to calculate total and fasting heat production in order to determine net energy in complete diets and feed ingredients fed to pigs under commercial conditions. Adapted from a presentation at the 6th EAAP International Symposium on Energy and Protein Metabolism and Nutrition, September 9–12, 2019 in Belo Horizonte, MG, Brazil.

Diego Rodriguez, a research specialist in the Stein Monogastric Nutrition Lab, shares the results of two experiments to determine the effect of extrusion on ileal digestibility of amino acid and starch, apparent total tract digestibility of fiber and gross energy, and concentration of digestible and metabolizable energy in corn, wheat, and sorghum fed to pigs.

Hannah Bailey, a Ph. D. student in the Stein Monogastric Nutrition Lab, shares the results of two experiments to determine the protein quality of nine pork products and eight beef products using the digestible indispensable amino acid score (DIAAS).

Woongbi Kwon, a Ph. D. student in the Stein lab, shares the results of his research into the effects of dietary leucine concentration on branched-chain amino acid metabolism in growing pigs. Adapted from a presentation given at the 2019 ASAS Midwestern Section meeting, Omaha, NE, March 11-13.

Carly Rundle, Ph. D. candidate in the Stein Monogastric Nutrition Lab, presents her research into the effects of adding isoquinoline alkaloids, a phytobiotic feed additive used as an alternative to antibiotic growth promoters, to corn-soybean meal diets fed to weanling pigs.
