Announcing our new feed ingredient database

Our new feed ingredient database contains information on nutrient composition and digestibility for over 200 feed ingredients, oils, and minerals. Data for both pigs and poultry are included.

Research report: Concentrations of digestible, metabolizable, and net energy in soybean meal produced in different areas of the United States and fed to pigs

One factor that affects the chemical composition of soybeans and soybean meal is where the beans were grown. For instance, soybeans grown in the northern United States contain less crude protein than soybeans grown further south. As a result, soybean meal produced from beans grown in the Northern United States often contain less crude protein than soybean meal produced from beans grown further south. However, less is known about how the concentrations of digestible (DE), metabolizable (ME), and net (NE) energy differs among meals produced from soybeans grown in different areas of the U.S. Therefore, an experiment was conducted to determine the digestibility of energy and concentrations of DE, ME, and NE in soybean meal produced from soybeans grown in different areas of the U.S. and fed to growing pigs.

Research report: Effects of Caromic 105 on growth performance of weanling pigs

The carob tree (Ceratonia siliqua) is an evergreen native to the Mediterranean area. Its fruit, technically a legume, consists of leathery brown pods that contain hard brown seeds in a sweet pulp. The pods can be crushed, with or without the seeds, to produce a meal that is fed to animals. Because carob pod meal contains 40-45% sugars, it promotes feed intake and adds energy to the diet. Carob pods also contain tannins. As inclusion rates of carob pod meal increase, the tannins can inhibit nutrient digestibility, which limits carob inclusion in swine diets. However, at lower inclusion rates, carob pod meal can reduce the incidence of diarrhea in weanling pigs due to the tannins' effect on the intestinal mucosa.

Caromic 105 is a deseeded, toasted, micronized carob pod meal product. An experiment was conducted to determine the effect of Caromic 105 on growth performance of weanling pigs.

Podcast: Effects of microbial phytase on digestibility of calcium in calcium supplements fed to growing pigs

Caroline González-Vega is a Ph.D. candidate in the Stein Monogastric Nutrition Lab. She describes an experiment to determine the effect of microbial phytase on the standardized total tract digestibility of calcium in monocalcium phosphate, dicalcium phosphate, calcium carbonate, L. calcareum calcium, and sugar beet coproduct fed to growing pigs. Adapted from a presentation at the 2014 ASAS Midwestern Section meeting, Des Moines, IA, March 17-19.

Press release: Study looks at calcium in canola meal as part of pig diet

URBANA, Ill. – When formulating diets for pigs, it is more accurate to use values for standardized or true nutrient digestibility than values for apparent nutrient digestibility because the former are additive in mixed diets. Research at the University of Illinois is helping to determine the true digestibility of calcium in swine diets.

Hans Stein, a professor of animal sciences at the U of I, led the team that conducted the study. "We know that there are endogenous losses of calcium in cattle and chickens, and our hypothesis was that the same is true for pigs," Stein said. "We also wanted to determine if adding microbial phytase to the diets would affect endogenous losses of calcium."
