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. Abstract An...

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....

Addition of probiotics to swine diets may improve gut health by modifying the microflora, which may help control pathogens, enhance immune response, and increase nutrient digestibility. Once consumed by the pig, probiotics enter the stomach where they are subjected...
Michael Schwirtz, Andrew E. Kramer and Michael Levenson reported on the front page of Sunday’s New York Times that, “President Vladimir V. Putin warned on Saturday that crippling economic sanctions imposed by the West were ‘akin to a declaration...
