corn protein

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.
