چکیده
s of papers 41 (H=79.9 vs. I=81.0 eggs), and M (H=5.4 vs. I=20.9%). Also, strain effected (p<.001) bone BS (H=14.26 vs. I=12.26 kg) and volume (H=5.90 vs. I=6.27 cc). These results indicate that strain influences performance and bone parameters and suggest that increased Ca and P levels impact bones of laying hens only if provided during the rearing phase.

بررسی تأثیر سطوح مختلف انرژی و نسبت انرژی به پروتئین جیره بر عملکرد مرغ‌های تخم‌گذار بومی استان فارس در مرحله دوم تخم‌گذاری
The effects of different levels of metabolizable energy and energy to protein ratios on the performance of Fars native laying hens were examined during the second laying phase. In a feeding trial, 216 Fars native hens 42 weeks old were randomly allotted to 9 experimental diets using 6 replicated groups of 4 birds per cage. The diets were formulated with 3 levels of ME (2700, 2900 and 3100 kcal/...
