The residual activities of transgenic corn-derived and 2 commercial microbial phytases (PA and PB) along the gastrointestinal tract (GIT) of laying hens were compared to evaluate their relative resistance to hydrolysis in the GIT when added to P-deficient diets. The treatments consisted of a negative control (NC) diet containing 0.10 nonphytate P and an NC diet supplemented with transgenic corn...
A 2×2×2 factorial arrangement with control group was conducted to study the effect of different levels of microbial phytase, metabolizable energy and available phosphorus on performance, carcass characteristics and phosphorus and calcium content of tibia in broiler chicks. In this experiment, 1260 Ross 308 male broiler chicks allocated to 9 treatments in a factorial arrangement, with 2 levels o...
A total of 360 pigs (200 × 400, DNA; initially 21.9 ± 0.42 lb) were used in a 21-d growth trial to determine the available P (aP) release curve for GraINzyme Phytase (Agrivida Inc., Woburn, MA). Pigs weaned at approximately 21 d age, randomly allotted pens based on initial BW and fed common starter diets. From 18 post-weaning, all diet containing 0.11% aP. On considered 0 study, blocked by 1 8 ...
A 2 x 2 x 2 factorial experiment was conducted with 64 pigs (4 wk old, 8.04 +/- .50 kg BW) to determine the effect of various dietary concentrations of Ca, vitamin D, and microbial phytase (Aspergillus niger) on phytate-P utilization. A low-P, corn-soybean meal diet was supplemented with two levels of phytase (unit/gram), 750 (suboptimal) and 1,200 (optimal); of vitamin D (international unit/ki...
the effect of ascorbic acid (aa) and butylated hydroxyanisole (bha) supplementation on aflatoxicosis in broiler chickens (1 to 42 days of age) was investigated (250, 500, 1000 and 2000 ppm for aa and bha) in diet containing 1 ppm total aflatoxin (af: 76.45% afb1, 10.52% afb2, 9.89% afg1 and 3.14% afg2). a total of 300 day-old broiler chicks were divided into ten treatment groups (t1=control; t2...
This experiment evaluates the effect of decreasing dietary CP, in addition to the effects of dietary supplements of L-Thr to low CP diets, in Large White Nicholas toms from 0 to 18 wk of age. Toms were fed dietary treatments consisting of four levels of dietary CP as a percentage of NRC (1994) recommendations (100, 92, 84, and 76% of NRC recommendations). Additional treatments consisted of supp...
In a previous study, several histological alterations were found in the liver of gilthead seabream Ž . fed with a diet containing 30% soybean meal SBM . In the current study, SBM containing diets Ž . were supplemented with either potassium phosphate, zinc sulfate or phytase Aspergillus ficuum , or increasing the dietary ny3rny6 fatty acids ratio to meet that of a fish meal based diet. Diet Ž . ...
The efficacy of a thermotolerant 6-phytase on performance and apparent total tract digestibility (ATTD) of P and Ca was evaluated in 96 crossbred barrows (8 replicates with 3 pigs each) fed 4 diets. Diets based on corn (Zea mays), a heat-treated grain mix, and soybean (Glycine max) meal with recommended [positive control (PC)] or reduced [negative control (NC)] P and Ca levels were fed from 25 ...
for DDGS relative to MSP were 84.3% and 85.3% for fibula breaking load and fibula bone ash, respectively. The basal diet + 500 FTU/kg phytase resulted in greater fibula breaking load (18.7 vs 13.7 kg force) and bone ash (1.049 vs 0.896 g) as compared with the basal diet, resulting in calculated P release of 0.082 and 0.064%, respectively. The 0.225% P DDGS + 500 FTU/kg phytase also resulted in ...
in order to study the effects of various levels of protein in diet based on total and digestible amino acids on performance and carcass traits of broilers, an experiment was conducted as a completely randomized design with 288 broiler chicks from cobb 500 strain in 6 treatments, each treatment consist of 3 replicates with 16 chicks per replicate. treatments were the diets as follow: 1) diet for...
