Effects of low-phytic acid corn, low-phytic acid soybean meal, and phytase on nutrient digestibility and excretion in growing pigs.
Forty-eight grower pigs were used to evaluate the effects of feeding low phytic acid (LPA) corn, LPA soybean meal, normal corn (NC), normal soybean meal (NSBM), and phytase on nutrient digestibility and excretion. Barrows were blocked by BW (initial BW=45.3+/-1.6 kg) and randomly assigned to 1 of 8 dietary treatments in a 2 x 2 x 2 factorial arrangement (6 pigs/treatment). Pigs were fed twice d...
متن کاملEffects of Low Phytic Acid Corn, Low Phytic Acid Soybean Meal and Phytase on Nutrient Excretion and Nutrient Digestibility in Pigs
Environmental concerns associated with animal agriculture are of the utmost interest to producers and regulators alike. In December 2002 the United States Environmental Protection Agency is scheduled to release new regulations that will attempt to guide manure management practices for all production levels of animal agriculture. A proposed component of the new regulations is to require a compre...
متن کاملEffects of phytase on amino acid and energy digestibility in corn–soybean meal diets fed to growing pigs
An experiment was conducted to determine whether the effects of phytase on amino acid (AA) and energy digestibility in pigs is influenced by the concentration of dietary P. Fourteen barrows (initial BW: 37.8 ± 4.7 kg) were surgically fitted with a T-cannula in the distal ileum and randomly allotted to a replicated 7 × 7 Latin square design with 7 diets and 7 periods. Six diets were formulated t...
متن کاملEffects of low phytic acid corn on phosphorus utilization, performance, and bone mineralization in broiler chicks.
In vivo and in vitro experiments were conducted to determine whether P in a low-phytate corn (LPC) containing the lpa 1-1 allele is more available than P in a near-isogenic wild-type corn hybrid (NC). The LPC was analyzed to contain 0.18% nonphytate P and 0.26% total P (TP), whereas NC contained 0.05% nonphytate P and 0.25% TP. For these studies, nonphytate P was considered to be available P (A...
متن کاملCalcium, phosphorus, and amino acid digestibility in low-phytate corn, normal corn, and soybean meal by growing pigs.
Nine growing barrows were equipped with a T-cannula in the distal ileum and used to determine apparent ileal (AID) and apparent total-tract digestibility (ATTD) coefficients of Ca and P in low-phytate corn, normal corn, soybean meal, and in diets where soybean meal was mixed with low-phytate corn or normal corn. The AID and the standardized ileal digestibility coefficients (SID) of CP and AA al...
