Interaction of calcium and phytate in broiler diets. 1. Effects on apparent prececal digestibility and retention of phosphorus.
Phytate P utilization from soybean meal (SBM) included in broiler diets has been shown to be poor and highly dependent on dietary Ca intake. However, the effect of Ca on P utilization and on the optimal ratio of Ca to nonphytate P (Ca:NPP) when diets contained varying levels of phytate has not been clearly shown and was the objective of this research. A factorial treatment structure was used wi...
متن کاملInteraction of calcium and phytate in broiler diets. 2. Effects on total and soluble phosphorus excretion.
Dietary Ca has been reported to influence the amount of phytate excreted from broilers and affect the solubility of P in excreta. To address the effects of dietary Ca and phytate on P excretion, 12 dietary treatments were fed to broilers from 16 to 21 d of age. Treatments consisted of 3 levels of phytate P (0.10, 0.24, and 0.28%) and 4 levels of Ca (0.47, 0.70, 0.93, and 1.16%) in a randomized ...

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 اولIleal Digestibility and Bone Retention of Calcium in Diets Containing Eggshell, Oyster Shell or Inorganic Calcium Carbonate in Broiler Chickens
This study was conducted to compare ileal digestibility of calcium, dry matter and ash, growth performance, gut characteristics, bone parameters and retention of calcium in broiler chickens fed diets containing different calcium sources. A total of 96 commercial Ross 308 broiler chickens were allocated to three experimental diets. The experimental diets included a diet containing inorganic calc...
متن کاملEffects of Citric Acid on Growth Performance and Nutrient Retention of Broiler Chicken Fed Diets Having Two Levels of Non-Phytate Phosphorus and Rice Bran
Citric acid has been reported to increase utilization efficiency of dietary phytate-bound phosphorus and protein. Objective of this study was to determine the effects of citric acid on growth performance and nutrient retention of broiler chickens fed diets having two levels of non-phytate phosphorus and rice bran. Giving a completely randomize design in 2 × 2 × 2 factorial arrangement, 144 broi...
