Carly Rundle, Ph. D. candidate in the Stein Monogastric Nutrition Lab, reviews the effects of supplementation with isoquinoline alkaloids on digestibility of crude protein, amino acids, starch, and acid hydrolyzed ether extract in growing and finishing pigs. Isoquinoline alkaloids are phytogenic compounds with antimicrobial, anti-inflammatory, and immunomodulatory properties. They are believed to improve nutrient digestion and absorption by reducing intestinal inflammation and improving intestinal barrier function.

Dr. Su A Lee, a recent graduate from the Stein Monogastric Nutrition Lab, presents data from her Ph. D. work and other experiments to determine the digestibility of calcium and phosphorus in growing pigs and gestating sows.

Hannah Bailey, a Ph. D. student in the Stein Monogastric Nutrition Laboratory, provides an overview of the work done in our lab to determine digestible indispensable amino acid score (DIAAS) values for edible nuts as well as pork and beef cuts processed in different ways and at different temperatures. Adapted from a presentation at the 2020 Virtual Annual Meeting of the American Oil Chemists' Society, June 29-July 3.
Dr. Su A Lee, a recent graduate from the Stein Monogastric Nutrition Lab, talks about how dietary amino acid concentration affects the standardized ileal digestibility (SID) of amino acids in feed ingredients, and demonstrates that AA SID can be determined in pigs fed diets below, at, or slightly above crude protein requirements without affecting the result. Adapted from a presentation at the 2020 ASAS Midwestern Section meeting, Omaha, NE, March 2-4.
Hannah Bailey, a Ph. D. student in the Stein Monogastric Nutrition Laboratory, discusses an experiment she conducted to determine the protein digestibility corrected amino acid score (PDCAAS) and the digestible indispensable amino acid score (DIAAS) for raw and roasted pistachio nuts fed to growing pigs. Another objective of this study was to assess the effect of roasting on these measurements of protein quality.

Dr. Su A Lee, a recent graduate from the Stein Monogastric Nutrition Lab, discusses the effects of dietary calcium on digestibility and retention of phosphorus as well as bone turnover biomarkers such as CTX-I, osteocalcin, and bone alkaline phosphatase. Adapted from a presentation at the 2020 ASAS Midwestern Section meeting, Omaha, NE, March 2-4.
Hannah Bailey, a Ph. D. student in the Stein Monogastric Nutrition Laboratory, presents the results of her research on amino acid digestibility and protein quality in brown rice protein concentrate, pea protein concentrate, two rapeseed protein isolates, soy protein isolate, and whey protein isolate. Based on a poster presentation for the American Society for Nutrition's "Nutrition 2020 Live Online" conference, June 1-4, 2020.
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.

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.

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.
