P122 Effects of phytase supplementation on ileal digestibility of phytate phosphorus and total phosphorus of feed ingredients for broiler chickens
This study aimed to evaluate the effect of a heat stable phytase derived from Citrobacter braakii on true digestibility of P and on phytate dephosphorylation at the terminal ileum segment in broiler chickens. Four semi-synthetic diets, each containing either wheat, maize, soybean meal or rapeseed meal as the only source of phosphorus and calcium were supplemented with microbial phytase at 1000 ...
متن کاملMeasurement of true ileal digestibility and total tract retention of phosphorus in corn and canola meal for broiler chickens.
The study reported herein was conducted to determine and compare the nonphytate P, digestible P, and retainable P contents of corn and canola meal for broiler chickens. Four semipurified diets were formulated from each of ingredient to contain graded concentrations of nonphytate P. The experiment was conducted as a randomized complete block design with 4 weight blocks of 8 cages each (6 birds p...
متن کاملMeasurement of true ileal digestibility of phosphorus in some feed ingredients for broiler chickens.
An experiment was conducted to estimate the true ileal digestibility of P in wheat, sorghum, soybean meal, and corn distiller's dried grains with solubles (DDGS) in broiler chickens. Four semipurified diets were formulated from each ingredient (wheat and sorghum: 236.5, 473, 709.5, and 946 g/kg; soybean meal and corn DDGS: 135, 270, 405, and 540 g/kg) to contain graded concentrations of nonphyt...
متن کاملTrue phosphorus digestibility of black-eyed pea and peanut flour without or with phytase supplementation in broiler chickens.
Two studies were conducted to determine the true P digestibility (TPD) of black-eyed pea (BEP) and peanut flour (PNF) and the TPD response to phytase supplementation using the regression method. Sequential diets containing 115, 230, or 345 g of BEP/kg (experiment 1) and 115, 230, or 345 g of PNF/kg (experiment 2) without or with 1,000 units of phytase/kg were formulated. Chromic oxide was added...
متن کاملthe effect of oxytetracycline on serum calcium, phosphorus and magnesium in cattle
نتایج این مطالعه نشان می دهد که مقدار کلسیم (یونیزه و تام)، منیزیم و فسفر به طور معنی داری تغییر پیدا کرد به جزء مقدار کلسیم تام و منیزیم در روش داخل عضلانی که تغییر معنی داری نداشته است. بر اساس نتایج این مطالعه می توان نتیجه گیری کرد که اکسی تتراساکلین بر روی مقادیر سرمی کلسیم و منیزیم تأثیر می گذارد باید مقدار این کاتیون ها در بیماران، در هنگامی که اکسی تتراسایکلین استفاده می شود مورد توجه ق...
