Effect of phytase on weaning piglet performance when fed diets supplemented with pharmacological levels of Zn

Pharmacological levels of Zn (i.e., 2,000 to 3,000 mg/kg) is often included in diets for weanling pigs to prevent post-weaning diarrhea. However, pharmacological levels of Zn may reduce microbial phytase efficacy by chelating the phytate molecule, which subsequently prevents access for phytase. However, it is possible that this effect can be reduced by adding more phytase to diets. Therefore, an experiment was conducted to test the hypothesis that inclusion of increasing levels of phytase increases pig growth performance and mineral digestibility in diets with 3,000 mg/kg of Zn.

Digestibility of P and concentrations of digestible and metabolizable energy in high-oil corn fed to growing pigs

Conventional breeding of corn has generated a new variety (i.e., high-oil corn; Byron Seeds LLC, Rockville, IN), which is believed to contain more oil and phosphorus than conventional corn. Because of the increased oil, it is possible that high-oil corn contains more digestible energy (DE) and metabolizable energy (ME) than conventional hybrids, but this hypothesis has not been experimentally verified. Inclusion of microbial phytase in diets for pigs usually improves digestibility of P because phytase hydrolyzes the ester bond that binds P to the phytate molecule in corn. However, there are at this point no data for effects of adding phytase to diets containing high-oil corn and no data to demonstrate the nutritional value of high-oil corn. Therefore, an experiment was conducted to test the hypothesis that the standardized total tract digestibility (STTD) of P, as well as concentrations of DE and ME in high-oil corn are greater than in conventional corn. The second hypothesis was that inclusion of microbial phytase to diets improves the STTD of P in corn sources.

Digestibility of amino acids in high-oil corn product fed to growing pigs

Corn is a cereal grain that is commonly used as a feed ingredient for swine diets due to its excellent palatability, and it can easily be grown on a wide range of environmental conditions. Conventional breeding of corn has generated a new variety (i.e., high-oil corn; Byron Seeds LLC, Rockville, IN), which is believed to contain more oil and crude protein (CP) than conventional corn. It is, therefore, possible that this high-oil corn may be comparable to other cereal grains and may serve as alternative to corn for pigs. However, there are at this point no data to demonstrate the nutritional value of high-oil corn. Therefore, an experiment was conducted to test the hypothesis that the standardized ileal digestibility (SID) of amino acids (AA) in high-oil corn is greater than in conventional corn.

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.

Conditioning and expansion increase nutritional value of soybean expellers

Soybean expellers contain trypsin inhibitors, which negatively affect nutrient digestibility, feed efficiency, and health status of animals. Therefore, heat treatment is needed to inactivate trypsin inhibitors to improve nutrient digestibility in soybean expellers. Different types and degrees of processing conditions may influence digestibility of energy and amino acids (AA) in soybean expellers, but there is a lack of data demonstrating how long heat treatment is needed if soybean expellers are expander processed after hydrothermical conditioning. Therefore, 2 experiments were conducted to test the hypothesis that the standardized ileal digestibility (SID) of AA, as well as values for digestible energy (DE) and metabolizable energy (ME) in soybean expellers increase the longer heat is applied to the expellers.
