ABSTRACT
A breed and three crossbreds (Fay, RIRxFay, NNxRIR, NNxFay) were studied for egg quality at different age under semi-scavenging system of management. The egg weight was highest (41.87, 44.03, 44.7 and 46.97 g) for RIR x Fay at sexual maturity, one, two and three months after sexual maturity. RIRxFay showed the highest (0.335, 0.337 and 0.340 mm) shell thickness and Albumen height (7.77, 8.48, 8.54 mm) at sexual maturity, one and three months after sexual maturity with exception at 2 months after sexual maturity (0.320 and 8.02 mm) for shell thickness and albumin height, respectively. Although yolk height was highest in case of RIR x Fay at sexual maturity NNxFay and NNxRIR showed the highest (19.82 and 19.03 mm), respectively for the next 2 months and at 3 months after sexual maturity NNxFay was found to be highest (19.93 mm). The highest yolk colour score (10.78) was in RIRxFay at sexual maturity and there after decreased over time. In case of Haugh unit RIRxFay showed the highest (77.7 and 82.21) at sexual maturity and 3 months after at sexual maturity but NNxFay and Fay showed the highest (83.17 and 82.29) at one month and two months after sexual maturity, respectively. It may be concluded that RIRxFay might be the best for quality egg production under semi-scavenging system of management.
