ABSTRACT An experiment was conducted to evaluate the effect of selection for egg production performance of Cairo L-2 strain, as a local layer strain, after five generations of selection on productivity, ovarian morphology and some egg quality traits versus commercial Lohmann Brown-Lite (LBL) strain. The performance in the 5th generation was evaluated in Cairo L-2 and LBL strains for live body weight at sexual maturity (BWSM), age at sexual maturity (ASM), first egg weight (FEW), ovarian morphology, ovarian follicles number, ovarian weights and diameter, oviduct weight, liver weight, and stroma weight and their percentages to live body weight at sexual maturity for Cairo L-2 and LBL strains. Egg traits at 36 weeks of age including: egg number (EN), egg... |
