Both 1,25-dihidroxyvitamin D3 and phytase are known to improve phosphorus utilization in broilers(Biehl and Baker,J Nutr 1997). Solanum glaucophyllum(Sg) is a plant containing high amounts of 1,25dihydroxyvitamin D bound to a glycoside. It may be an economical source of 1,25-dihydroxyvitamin D for animal feeds. We examined the effect of Sg, with and without phytase, on phosphorus utilization in...

This experiment was conducted to investigate the effects of supplemental phytase in a corn-wheatsoybean meal basal diet on phosphorus (P) digestibility and performance of broiler chicks. 378 one-day old broiler chicks (Ross 308) were allocated to 3×3 factorial arrangements with three levels of phytase enzyme (0, 500 and 1000 FTU/kg) and three levels of non-phytate P (100, 80 and 60% of NRC requ...

A study was conducted to study the effects of thermostable phytase supplementation on the growth performance and Ca and P metabolism of broilers for 21 d. 1-day-old Arbor Acres chicks with similar initial body weight were randomly divided into 3 treatments consisting 8 pens of 10 chicks per pen. The control group was given maize-soybean meal basal diet, and the other two groups were fed the bas...

The regression method was used in a 14-d broiler chicken study to determine the true ileal digestibility of amino acid (AA) and protein utilization in canola meal (CM, 388 g of CP/kg) without or with added phytase. Experimental treatments consisted of 2 factors, phytase at 2 levels (0 or 1,500 phytase units/kg) and CM at 3 levels (125, 250, or 375 g/kg). Birds received a standard starter diet f...

A study was conducted to evaluate the impact of feeding soybean meal (SBM) from low-phytate (LP) or traditional phytate (TP) soybeans on performance and excretions from growing swine. Ninety-six crossbred barrows (initial BW = 18 +/- 0.3 kg) were allocated by BW to 24 pens and fed 1 of 4 treatment diets: TP SBM without supplemental phytase; TP SBM plus 500 phytase units of phytase/kg, as-fed ba...

Bacillus amyloliquefaciens DS11 phytase (DS11 phytase) and Aspergillus ficuum phytase (AF phytase) activities were investigated by measuring the release of phosphate from phytate in animal feedstuff such as wheat bran, corn meal, soybean meal and rice flour at pH 5 and 7. In all the tested feedstuff, the enzymatic activity of DS11 phytase was more active at pH 7, but that of AF phytase was more...

The objective was to quantify the retention of digesta and evaluate the degradation of phytate or inositol hexakisphosphate (InsP(6)) and lower inositol phosphates (InsP₅, InsP₄, InsP₃, and InsP₂) in the stomach at different times after feeding pigs a fermented liquid diet with microbial phytase or a nonfermented diet with or without microbial phytase. Six barrows fitted with gastric cannulas w...

Two experiments involving 115 pigs were conducted to assess the efficacy of a microbial phytase (Allzyme Phytase; Alltech, Nicholasville, KY) produced by Aspergillus niger in low-P, corn-soybean meal-based diets. The phytase supplement contained 50 phytase units/g and 1.43% P. In Exp. 1, growing-finishing pigs were fed fortified corn-soybean meal diets formulated to be adequate (.50%) or inadeq...

BACKGROUND Endogenous phytase plays a crucial role in phytate degradation and is thus closely related to nutrient efficiency in barley products. The understanding of genetic information of phytase in barley can provide a useful tool for breeding new barley varieties with high phytase activity. METHODOLOGY/PRINCIPAL FINDINGS Quantitative trait loci (QTL) analysis for phytase activity was condu...
