Caroline Gonzalez-Vega is a master's student in the Stein Monogastric Nutrition Lab. She describes an experiment to determine the endogenous losses of calcium from the intestinal tracts of pigs fed canola meal, and to use that information to calculate the true total tract digestibility of calcium in canola meal. Adapted from a presentation at the 2012 ADSA-AMPA-ASAS-CSAS-WSASAS Joint Annual Meeting, Phoenix, AZ, July 15-19.

Ferdinando Almeida, Ph. D. student in the Stein Monogastric Nutrition Lab, presents the results of an experiment to determine amino acid digestibility in different sources of feather meal, with and without the addition of blood. Adapted from a presentation at the 2012 ADSA-AMPA-ASAS-CSAS-WSASAS Joint Annual Meeting, Phoenix, AZ, July 15-19.

Ferdinando Almeida, Ph. D. student in the Stein Monogastric Nutrition Lab, presents the results of an experiment to determine amino acid digestibility in camelina seeds and camelina expellers, and to compare them to canola meal. Adapted from a presentation at the 2012 ADSA-AMPA-ASAS-CSAS-WSASAS Joint Annual Meeting, Phoenix, AZ, July 15-19.

Ferdinando Almeida, Ph. D. student in the Stein Monogastric Nutrition Lab, presents the results of an experiment to determine amino acid digestibility in spray dried blood products and two sources of blood meal. Adapted from a presentation at the 2012 ADSA-AMPA-ASAS-CSAS-WSASAS Joint Annual Meeting, Phoenix, AZ, July 15-19.

Dr. Hans H. Stein discusses the new edition of Nutrient Requirements of Swine from the National Research Council. Dr. Stein describes the process of developing the new NRC, the new and updated information in the 11th Edition, and areas where further research is needed.

Dr. Hans H. Stein presents the results of research into the concentration of digestible and metabolizable energy in new DDGS products with reduced fat content.

Dr. Hans H. Stein examines the effects of feeding different forms of dietary fiber on energy utilization and nutrient digestibility in swine diets. Dr. Stein also discusses physical, chemical, and enzymatic treatment of fibers to improve their utilization by pigs.

Jin Yoon, master's student in the Stein Monogastric Nutrition Lab, presents the results of two experiments to determine the energy concentration and amino acid digestibility of high protein and low oligosaccharide soybean varieties, and to compare them to conventional soybeans.

Dr. Hans H. Stein discusses the use of soybean products in swine diets. Topics covered include composition, protein quality and digestibility, energy content and digestibility, phosphorus digestibility and use of phytase, and the effect of heat damage on soybean meal.

Jung Wook Lee, master's student in the Stein Monogastric Nutrition Lab, presents the results of an experiment to determine the optimal inclusion rate of corn germ in growing to finishing pig diets containing 0 or 30% DDGS.
