corn protein

Digestibility of energy and concentrations of digestible and metabolizable energy in three sources of corn protein fed to weanling pigs

Corn coproducts produced from the fuel ethanol or the wet milling industries may be used in diets for pigs. Different technologies are used to develop high protein corn co-products, but in addition to providing amino acids to the diets, high protein corn co-products also provide energy to the diets. The energy concentrations in corn protein may depend on the concentrations of fat, carbohydrates, and protein in sources of corn protein. Newly developed corn proteins contain 40 to 50% crude protein. There are, however, limited data on how differences in the chemical composition of different sources of corn protein influence the concentrations of digestible energy (DE) and metabolizable energy (ME) when fed to weanling pigs. Therefore, the objective of this experiment was to test the null hypothesis that there is no difference in the apparent total tract digestibility (ATTD) of gross energy (GE) and concentrations of DE and ME among 3 sources of corn protein when fed to weanling pigs.

Standardized ileal digestibility of amino acids in three sources of corn protein fed to weanling pigs

Corn coproducts produced from the fuel ethanol or the wet milling industries may be used in diets fed to pigs. Newly developed corn proteins are high protein feed ingredients with approximately 40 to 50% crude protein (CP), and corn protein may be a great source of digestible amino acids (AA) in diets fed to weanling pigs. There are, however, limited data on the digestibility of AA in different sources of corn protein fed to weanling pigs. Therefore, the objective of this experiment was to test the null hypothesis that there is no difference in the standardized ileal digestibility (SID) of AA in 3 different sources of corn protein when fed to weanling pigs.

Digestibility of energy and concentrations of digestible and metabolizable energy in a high protein corn product fed to growing pigs

A new source of corn protein (NexPro) that is produced from the ethanol industry has been developed by Flint Hills Resources (Wichita, KS). NexPro contains approximately 50% crude protein and the digestibility of amino acids was reported in our November, 2020, Newsletter. However, there is at this time no information about the concentration of digestible energy (DE) and metabolizable energy (ME) in this new source of protein. Therefore, the objective of this experiment was to test the hypothesis that concentrations of DE and ME in corn protein are greater than in 2 sources of distillers dried grains with solubles (DDGS; i.e., DDGS-1 and DDGS-2) when fed to growing pigs.

Digestibility of amino acids in a high protein corn product fed to growing pigs

Corn coproducts produced from the ethanol industry are often used in diets for pigs. A new source of corn protein (NexPro; Flint Hills Resources, Wichita, KS) has been developed, but at this time there is limited information about the nutritional value of this new source of corn protein. Therefore, the objective of this experiment was to test the hypothesis that the standardized ileal digestibility (SID) of amino acids  in corn protein is greater than in 2 sources of distillers dried grains with solubles (DDGS; i.e., DDGS-1 and DDGS-2) when fed to growing pigs.
