Effects of increasing dietary protein on standardized ileal digestibility of amino acids in diets fed to growing pigs

Apparent ileal digestibility (AID) of amino acids (AA) is affected by dietary AA levels because of different contributions of endogenous AA to the ileal digesta from pigs fed diets with different levels of AA. Because of the influence of dietary protein and AA on calculated values for AID, values for AID obtained in individual feed ingredients are not always additive in mixed diets. Therefore, values for standardized ileal digestibility (SID) of AA, which are corrected for the basal ileal endogenous losses of AA, are used in diet formulations to avoid the influence of endogenous AA on digestibility values, and SID values are, therefore, additive in mixed diets.

When the direct procedure is used to determine AA digestibility, diets containing cereal grains are sometimes formulated to contain AA below the requirement. In contrast, if the SID of oilseed meals or other protein-rich ingredients are determined, concentrations of AA may be at or above the requirement. Because the influence of the basal endogenous losses of AA is eliminated in the calculations of SID values, it is assumed that values for SID are not influenced by dietary concentrations of AA. However, to our knowledge this hypothesis has not been experimentally verified, but it is an important question because it may influence how diets used in digestibility experiments are formulated. Therefore, four experiments were conducted to test the hypothesis that the SID of AA by growing pigs is not influenced by dietary AA levels.

Effects of different corn sources and drying temperature on ileal digestibility of starch and amino acids in diets fed to growing pigs

Drying temperatures and corn varieties that inherently differ in kernel hardness, virtuousness, and protein solubility index may influence nutrient digestibility in corn. However, information about interactive effects of corn source (i.e., endosperm hardness) and drying method on nutrient digestibility is limited. Therefore, an experiment was conducted to test the hypothesis that the ileal digestibility of starch, crude protein (CP), and amino acids (AA) is influenced by corn source and drying temperature.

Standardized ileal digestibility of amino acids is not affected by reducing particle sizes or different origins of field peas fed to growing pigs

Field peas (Pisum sativum L.) have been cultivated for centuries for human consumption, due to the high nutritional quality of pea protein. However, during the last years, increasing demand for field peas for livestock feeding has developed a market in Canada, Europe, and the U.S. Therefore, as is the case with some feed ingredients, differences in soil, varieties, agronomic practices, and growing method may change the nutritional characteristics of the peas as well as the digestibility of nutrients. Besides that, differences in the particle size of field peas may change the digestibility of nutrients. Therefore, the objective of this experiment was to test the hypothesis that the standardized ileal digestibility (SID) of crude protein (CP) and amino acids (AA) in field peas is affected by the particle size of the field peas and the region where the field peas were grown.

Digestibility of amino acids in ten sources of wheat middlings fed to growing pigs

Data for the composition of wheat middlings from flour mills in the U.S. and for the standardized ileal digestibility (SID) of crude protein (CP) and amino acids (AA) have been published for wheat middlings from the U.S. However, it is not known if the data obtained from wheat middlings from the U.S. also are representative for wheat middlings in Europe. Therefore, an experiment was conducted to test the hypothesis that there are no differences in composition and SID of CP and AA between wheat middlings sourced from flour mills in Europe and in the U.S.
