Stein Lab scholars excel at home and abroad

Neil Jaworski, Ph. D. student in the Stein Monogastric Nutrition Laboratory, was selected to receive the David H. and Noraine A. Baker Graduate Fellowship for the 2015-2016 academic year. The Baker Fellowship in Animal Sciences annually recognizes an outstanding doctoral student in the Department of Animal Sciences at the University of Illinois at Urbana-Champaign.

Mary Dickerson, an undergraduate who works in the Stein Lab, is the first student to be accepted into the ACES in the Netherlands Summer Internship program. Mary will be working for a dairy farm in the Netherlands.

Research report: Concentrations of nitrogen-corrected apparent metabolizable energy and amino acid digestibility in soybean meal from Argentina, Brazil, China, Thailand and the United States fed to broilers

The nutritional value of soybean meal from different sources may vary due to differences in processing techniques and environmental conditions such as growing areas, soil type, and variety of soybeans. The Philippines import soybean for livestock feed from many different countries. However, the nutritional quality of soybean meal from these different origins has not been compared. It is important for producers formulating diets in the Philippines to know whether the same values can be used in formulations for all sources of imported soybean meal. Therefore, two experiments were conducted to determine the concentrations of apparent metabolizable energy (AME) and nitrogen-corrected apparent metabolizable energy (AMEn), and the standardized ileal digestibility (SID) of amino acids by broilers fed soybean meal from Argentina, Brazil, China, Thailand, and the United States.

Podcast: Concentration of energy in processed soybean and rapeseed products fed to pigs

Diego Navarro is a Ph. D. student in the Stein Monogastric Nutrition Lab. He discusses the results of an experiment to determine the concentration of digestible and metabolizable energy in two sources of enzyme treated soybean meal, an extruded soybean meal that was subsequently fortified with an enzyme treatment, a source of soy protein concentrate, conventional soybean meal, conventional 00-rapeseed expellers, and a fermented co-product mixture containing fermented rapeseed meal, wheat, soy molasses, and potato peel. Adapted from a presentation at the 2015 ASAS Midwestern Section meeting, Des Moines, IA, March 15-18.

Podcast: Use of feed technology to improve the nutritional value of feed ingredients fed to pigs

Dr. Oscar Rojas is a recent Ph. D. recipient from the Stein Nutrition Lab. In this podcast, he presents his doctoral research into the use of various feed processing technologies to improve the nutritional value of feed ingredients fed to pigs. Topics include:

  • Determining the concentration of DE and ME and the digestibility of P, AA, and starch in corn grain that was ground to different particle sizes and fed to growing pigs
  • Tests of the hypotheses that the addition of dietary lipids can be reduced as corn particle size is reduced without affecting growth performance or carcass characteristics, and that caloric utilization of corn fed to weanling pigs is increased if particle size of corn is reduced

  • Effects of extrusion and pelleting on energy and nutrient digestibility in diets with different levels of fiber fed to pigs

  • Effects of chemicals, physical, or enzymatic treatments on  concentration of ME and digestibility of energy in DDGS fed to pigs

Press release: Study determines nutritional value of canola oil co-products when fed to pigs

URBANA, Ill. – Rapeseed and canola are popular oilseed crops and co-products from these crops are increasingly used in livestock diets as a source of protein. Research at the University of Illinois is helping to determine the nutritional value of canola oil co-products fed to pigs.

"Breeding programs in North America and Europe have focused on selecting varieties of canola and rapeseed with low concentrations of erucic acids and glucosinolates," said Hans H. Stein, professor of animal sciences at the U of I. "We wanted to compare the co-products from the North American and European varieties, as well as determine effects of processing on the nutritional value of the co-products."
