Ileal and total tract digestibility of energy and nutrients in pig diets supplemented with a novel consensus bacterial 6-phytase

The effect of microbial phytase on Ca and P digestibility in diets for pigs and poultry is well established. In poultry, it also appears that the effect of phytase in increasing amino acid (AA) digestibility is consistent, but that is not the case when phytase is added to diets for pigs. However, in many experiments, relatively low levels of phytase was used and it is not known if greater concentrations of phytase will result in a different result. A novel phytase has been recently developed; however, it is also not known if this phytase source can increase digestibility of AA and other nutrients. Therefore, an experiment was conducted to test the hypothesis that inclusion of increasing levels of the novel phytase in diets for growing pigs increases the apparent ileal digestibility (AID) of crude protein (CP) and AA, and the apparent total tract digestibility (ATTD) of gross energy (GE) and minerals.

Growth performance of weanling pigs fed diets based on conventional corn or high-oil corn

Conventional breeding of corn has generated a new variety (i.e., high-oil corn) which is believed to contain greater concentrations of oil and crude protein than conventional corn. Indeed, results from digestibility experiments indicated that high-oil corn contained more standardized ileal digestible amino acids, digestible P, and metabolizable energy compared with conventional corn. It is, therefore, possible that the newly developed high-oil corn may improve pig growth performance, but data to demonstrate this are limited. Therefore, an experiment was conducted to test the hypothesis that high-oil corn improves growth performance of weanling pigs.

Growth performance of weanling pigs fed diets with spray-dried bovine plasma or hydrolyzed spray-dried bovine plasma

Spray-dried plasma protein is commonly used in weanling diets due its functional components and high concentration of digestible amino acids. Hydrolyzed spray-dried bovine plasma (H-SDBP) is a new source of spray-dried plasma protein that may be used as a protein source in diets for weanling pigs. There are, however, no data to demonstrate the efficacy of this novel source. Pigs fed diets spray-dried plasma protein have increased growth performance when exposed to a challenge model; therefore, it is possible that H-SDBP improves performance of challenged pigs similarly as other sources of spray-dried plasma protein. Therefore, an experiment was conducted to test the hypothesis that dietary inclusion of H-SDBP is as effective as spray-dried bovine plasma (SDBP) in increasing growth performance of weanling pigs housed in uncleaned pens.
