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 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...
15 صفحه اولPhytate utilization and phosphorus excretion by broiler chickens fed diets containing cereal grains varying in phytate and phytase content
Eighty, 12-day-old, male broiler chicks, were fed one of four diets to determine the effects of feeding grains varying in phytate phosphorus (P) and intrinsic phytase activity on ileal and excreta P digestibility and composition. The diets contained approximately 970.7 g grain kg−1 (maize, high fat–low lignin oat, normal barley or low-phytate barley) with the cereal supplying the sole source of...
متن کاملEffect of dietary calcium concentrations in low non-phytate phosphorus diets containing phytase on growth performance, bone mineralization, litter quality, and footpad dermatitis incidence in growing broiler chickens
OBJECTIVE An experiment was conducted to investigate the effect of dietary Ca concentrations in low non-phytate phosphorus (NPP) diets containing phytase on growth performance, bone mineralization, litter quality, and footpad dermatitis (FPD) incidence in growing broiler chickens. METHODS A total of 1,800 21-day-old Ross 308 growing broiler chickens were allotted to 1 of 6 dietary treatments ...
متن کاملEffects of steam pelleting and extrusion of feed on phytate phosphorus utilization in broiler chickens.
Three experiments were conducted to determine the effects of pelleting and extrusion of feeds on the utilization of phytate P by broilers. The first experiment investigated the effects of pelleting the whole corn-soybean meal (SBM) diet, the corn, or SBM separately on phytate P utilization. The P-deficient basal diet contained 0.5% total P and 0.2% phytate P. Steam pelleting the whole diet, the...
