In the third of three presentations based on his Master's thesis work, Diego Andres Lopez discusses the effect of supplementing microbial phytase on STTD of phosphorus in monocalcium phosphate, monosodium phosphate, and magnesium phosphate.

Joseph Limbach, a recent Master's degree recipient from the Stein Monogastric Nutrition Lab, presents his thesis research about the effects of dietary crude protein on measurements of health and performance in weanling pig. Topics include post-weaning diarrhea, growth performance, blood parameters, morphology of the jejunum and ileum, gastrointestinal pH, products of fermentation in the cecum and colon, and the expression of genes related to inflammation in the ileum.

In the second of three presentations based on his Master's thesis work, Diego Andres Lopez compares the digestibility of phosphorus in feed phosphates derived from volcanic and sedimentary rock.

Paola Lancheros, a Master’s student in the Stein Monogastric Nutrition Lab, presents the results of three experiments to determine the amino acid digestibility, concentrations of digestible and metabolizable energy, and phosphorus digestibility in torula yeast as compared with fish meal when fed to weanling pigs. Adapted from a presentation at the 2020 ASAS Midwestern Section meeting, Omaha, NE, March 2-4.

In the first of three presentations based on his Master's thesis work, Diego Andres Lopez looks at the concentrations of calcium, phosphorus, other beneficial macro and micro minerals, and potentially harmful minerals in commercially available feed phosphates.

Dr. Maryane Oliveira, a postdoctoral research associate in the Stein Monogastric Nutrition Lab, presents the results of a study in which xylanase and cellulase were added to corn- and sorghum-based diets fed to growing pigs to determine their effects on fiber digestibility, ATTD of gross energy, and metabolizable energy. Adapted from a presentation at the 2020 ASAS Midwestern Section meeting, Omaha, NE, March 2-4.

Vanessa Lagos, a Ph. D. candidate from the Stein Monogastric Nutrition lab, presents the results of an experiment designed to test the hypothesis that formulating diets based on a ratio between STTD calcium and STTD phosphorus instead of total calcium and STTD phosphorus will not affect calcium retention but will increase the efficiency of phosphorus utilization. Adapted from a presentation at the 2020 ASAS Midwestern Section meeting, Omaha, NE, March 2-4.

Vanessa Lagos, a Ph. D. candidate from the Stein Monogastric Nutrition lab, presents the results of an experiment designed to test whether ratios between STTD calcium and STTD phosphorus derived from multiple short-term studies of pigs at different stages of development may be applied to pigs fed diets without or with microbial phytase from 11 to 130 kg. Adapted from a presentation at the 2020 ASAS Midwestern Section meeting, Omaha, NE, March 2-4.

Jessica Acosta, a visiting scholar in the Stein lab, discusses ProCap DDGS, a high-protein co-product of the dry-grind ethanol industry. She reports the results of a study to determine the concentration and standardized ileal digestibility of crude protein and amino acids in ProCap and compares it with conventional DDGS and soybean meal. Adapted from a presentation at the 2020 ASAS Midwestern Section meeting, Omaha, NE, March 2-4.

Woongbi Kwon, a Ph. D. student in the Stein lab, investigates effects of dietary isoleucine and valine supplementation to excess or low leucine diets on nitrogen balance and metabolism of branched-chain amino acids in growing pigs. Adapted from a presentation at the 2020 ASAS Midwestern Section meeting, Omaha, NE, March 2-4.
