Abstract
Inclusion of high protein corn protein (HPCP) in diets for weanling pigs may result in diets with excess Leu being formulated, which may reduce growth performance. However, it was hypothesized that the negative effect of using HPCP in diets...

Abstract
Background Reduction of the particle size of corn increases energy digestibility and concentrations of digestible and metabolizable energy. Pelleting may also reduce particle size of grain, but it is not known if there are interactions between particle size reduction...
It is important that the digestibility of Ca in Ca sources is known to formulate diets based on values for digestible Ca rather than total Ca. Only a small amount of the Ca required by pigs is provided by...
Abstract
Data from Europe indicate that commercial diets for pigs and poultry contain significantly more Ca than formulated. Therefore, a survey of commercial pig diets used in the United States was conducted to test the hypothesis that the analyzed concentrations...
Corn is the primary grain used in pig diets and provides most energy to the diets. Because energy is the most expensive component in diet formulation, it is critical to accurately determine energy concentrations in corn. Use of exogenous...
Phosphorus is one of the most expensive nutrients in swine diets. Use of standardized total tract digestibility (STTD) of P, instead of apparent total tract digestibility (ATTD), may reduce the cost of diets because STTD values, unlike ATTD values,...
Highlights
•A xylanase-glucanase mixture increased digestibility of energy in diets for pigs.
•The response to enzymes was greater in sorghum based diets than in corn based diets.
•Wheat middlings and distillers dried grains with solubles reduced energy digestibility.

There are several factors related to dietary Ca that may influence digestibility of amino acids (AA). By chelating to dietary phytate, dietary Ca can form non-digestible Ca-phytate complexes, and this may result in reductions of P and AA digestibility....
