Research report: Requirement for digestible calcium by 25 to 50 kg pigs at different dietary concentration of phosphorus by growth performance and bone ash concentration

An excess of calcium in swine diets may increase excretion of phosphorus due to formation of Ca-P complexes. Therefore, when formulating diets for pigs, it is important to consider the ratio of calcium to phosphorus. The proper ratio should ensure that both minerals are maximally utilized in the bodies of the pigs.

A previous study conducted in the Stein Monogastric Nutrition Lab set out to determine the requirement for standardized total tract digestible (STTD) calcium in 11 to 25 kg pigs. More research is needed on STTD calcium requirements because until recently, digestibility data for calcium in feed ingredients were not available. Therefore, an experiment was conducted to determine the requirement for STTD calcium by 25 to 50 kg pigs needed to maximize average daily gain, gain:feed ratio, and bone ash at different concentrations of STTD phosphorus.

Press release: High-protein canola meal beneficial for growing pigs

URBANA, Ill. – A new study at the University of Illinois has determined that high-protein canola meal could prove to be a valuable ingredient in swine diets.

"Canola meal is an excellent plant-based source of protein that is often included in swine diets," said Hans H. Stein, a professor of animal sciences at U of I. "In recent years, canola varieties have been developed which contain greater concentrations of protein than conventional varieties. Our study has provided new information on the feed value of high-protein canola meal."

High-protein canola seeds have thinner hulls than conventional canola seeds. As a result, the meal derived from these seeds has a lower proportion of fiber, and a greater proportion of protein and oil, than conventional canola meal.
