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.

Influence of a novel consensus bacterial 6-phytase variant on mineral digestibility and bone ash in young growing pigs fed diets with different concentrations of phytate

Microbial phytase is usually included in diets for pigs to increase P absorption and utilization by hydrolyzing phytate within the gastrointestinal tract of pigs. High doses of phytase (i.e., > 1,000 FTU/kg) is also hypothesized to increase release of nutrients other than P due to increased degradation of phytate. A next generation biosynthetic bacterial 6-phytase (PhyG; DuPont Animal Nutrition) may increase digestibility of nutrients in diets for pigs; however, there are no data to demonstrate the efficacy of this phytase. Therefore, an experiment was conducted to test the hypothesis that the negative impact of phytate is reduced at higher phytase doses. It was also the objective of this research to test the hypothesis that inclusion of increasing levels of phytase increases bone ash and apparent total tract digestibility (ATTD) of minerals in diets containing varying phytate concentrations.

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.
