Estimation of true phosphorus digestibility and endogenous phosphorus loss in growing chicks fed conventional and low-phytate soybean meals.
This study evaluated regression of total P output against dietary P intake to simultaneously estimate endogenous P loss and true P utilization in broiler chicks. Soybean meal (SBM) served as the model ingredient, and a comparison was made between conventional and low-phytate SBM varieties. These feedstuffs were chosen to minimize nutritive differences to dietary phytate content. Low-phytate SBM...
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...
متن کاملPhosphorus acquisition and internal utilization efficiency in tropical maize genotypes
The objective of this work was to determine the relative importance of phosphorus acquisition efficiency (PAE – plant P uptake per soil available P), and phosphorus internal utilization efficiency (PUTIL – grain yield per P uptake) in the P use efficiency (PUE – grain yield per soil available P), on 28 tropical maize genotypes evaluated at three low P and two high P environments. PAE was almost...
متن کاملQuantitative conversion of phytate to inorganic phosphorus in soybean seeds expressing a bacterial phytase.
Phytic acid (PA) contains the major portion of the phosphorus in the soybean (Glycine max) seed and chelates divalent cations. During germination, both minerals and phosphate are released upon phytase-catalyzed degradation of PA. We generated a soybean line (CAPPA) in which an Escherichia coli periplasmic phytase, the product of the appA gene, was expressed in the cytoplasm of developing cotyle...
متن کاملEvaluation of low-oligosaccharide, low-phytate whole soybeans and soybean meal in canine foods.
Eight mature dogs (19.3 +/- 0.1 kg) were used in an experiment to compare the effects of feeding soybeans containing low concentrations of oligosaccharides and phytate on nutrient availability in complete foods fed to dogs. All foods were formulated to be isonitrogenous and contained low-oligosaccharide, low-phytate soybean meal (LLM); conventional soybean meal (SBM); low-oligosaccharide, low-p...
