Effects of super dosing 4 different sources of phytase on amino acid digestibility

Dietary phytate may bind to proteins from feed ingredients by making indigestible nutrient-complexes. Therefore, it is possible that adding exogenous phytase to the diets increases digestibility of amino acids (AA). However, results of experiments in which microbial phytase has been added to diets fed to pigs have not consistently demonstrated increased ileal digestibility of AA. It is, however, possible that is because the dose of phytase was too low to obtain a positive effect on AA digestibility and that if greater doses were used, a positive response would be obtained. Therefore, the objective of this experiment was to test the hypothesis that super dosing four different sources of commercially available exogenous phytase increases the apparent ileal digestibility (AID) of CP and AA in a corn-soybean meal (SBM) based diet fed to growing pigs.

Effects of intrinsic phytase from hybrid rye on P and Ca digestibility in a corn-soybean meal diet

Rye contains considerable quantities of intrinsic phytase and the presence of phytase in rye may result in an increased P digestibility in pigs without using exogenous phytase. It is possible that the endogenous phytase in rye also increases P digestibility in other plant feed ingredients by releasing P from the phytate. However, to our knowledge, no data demonstrating this effect have been published. Therefore, the objective of this experiment was to test the hypothesis that inclusion of rye in diets containing corn and soybean meal (SBM) without or with microbial phytase improves the apparent total tract digestibility (ATTD) of P and Ca and thus the ATTD of P is not additive in the mixed diet.

Digestibility of energy, and total dietary fiber, and concentration of digestible and metabolizable energy in soybean expeller and soybean meal fed to growing pigs

When soybeans are crushed, the oil may be solvent extracted and the resulting defatted soybeans are known as soybean meal (SBM). However, the oil may also be mechanically expelled from the beans and the defatted soybeans resulting from this procedure is an ingredient known as soybean expellers. The expelling procedure is less efficient in removing oil from the beans and soybean expellers, therefore, contain more residual oil than SBM. Soybean expellers can be produced using different technologies, and a new procedure involving a patented high shear dry extrusion procedure was recently developed (Insta-Pro International, Des Moines, IA). There are however, no data for the apparent total tract digestibility (ATTD) of GE and total dietary fiber (TDF) and DE and ME concentrations in the soybean expellers that are produced from this procedure. Therefore, the objective of this research was to test the hypothesis that the ATTD of GE and TDF and concentrations of DE and ME are greater in soybean expellers than in SBM when fed to growing pigs.

Digestibility of energy and phosphorus and concentration of metabolizable energy in a new source of high-protein distillers dried grains fed to growing pigs

Recently a high-protein distillers dried grains (HP-DDGS; ProCap DDGS, Marquis Energy, Hennepin, IL) was developed and the HP-DDGS has greater concentrations of CP and fat, but contains less fiber compared with conventional DDGS, which may affect the digestibility of energy and P and concentrations of DE and ME. There are, however, no data for the nutritional value of this new source of DDGS. Therefore, 2 experiments were conducted to test the hypothesis that concentrations of DE and ME, and standardized total tract digestibility (STTD) of P in HP-DDGS are greater than in conventional DDGS.
