اثر نوع منبع و سطح کلسیم جیره غذایی و اندازه ذرات سنگ آهک بر ویژگیهای تولیدی و سختی استخوان درشت نی در جوجه های گوشتی
An experiment was carried out on 384 7d old commercial broiler chicks (Lohman) to study the effect of changes in source and level of dietary calcium and limestone particle size on the performance and tibial growth and calcification of broiler chicks. From day 1 to day 7, the chicks were fed with the commercial basal diet. On day 7, the chicks were weighted and randomly assigned to 64 groups, si...

متن کاملEffect of dietary nonphytate phosphorus and calcium concentration on calcium appetite of broiler chicks.
The effect of dietary nonphytate P (nPP) and Ca concentration on the Ca appetite in broilers was evaluated. A total of 288 one-day-old male Ross 308 broilers were fed a commercial diet for 7 d then randomly allocated to 1 of 8 dietary treatments for a 28-d study. Diets were corn-soybean meal based and formulated to be nutritionally adequate except for nPP and Ca. Two concentrations of Ca (5.0 a...
متن کاملPhytase supplementation improved growth performance and bone characteristics in broilers fed varying levels of dietary calcium.
An experiment was conducted to investigate the effect of dietary Ca level on the efficacy of phytase. A total of 288 male Ross × Ross 708 broilers with initial and final BW of 37 and 705 g, respectively, were used in brooder batteries from 0 to 21 d posthatch. Each treatment had 8 replications with 6 broilers/replicate pen. All diets were corn-soybean meal based and formulated to contain 1.26% ...
متن کاملEffects of High Dietary Calcium and Low Phosphorus on Urinary System of Broiler Chicks
The present study was carried out to investigate the effects of high dietary calcium and low phosphorus on urinary system of broiler chicks. A total of 90 (day-old) broiler chicks were divided into three equal groups A, B and C. The chicks were reared for 42 days on three experimental rations. Calcium:phosphorus ratio in the feed for groups A, B and C was maintained as 1:0.5 (control), 2:0.5 an...
