ABSTRACT

This experiment was conducted to study the progress in productive performance of Tanta G-1 selected for high body weight at 8 weeks of age compared with the Mamourah local strain. The selection was applied for three generations. Body weight at sexual maturity (BWSM), age at sexual maturity (ASM), and egg production traits (EP) from 36 - 42 weeks of age were also applied. Our results showed that the average body weight for Tanta G-1 and Mamourah chicken strains was 866.45 grams and 558.75 grams in the first generation. In the second generation, the Tanta G-1 line’s body weight was 1006.50 grams against 555.10 grams for the Mamourah strain, while in the third generation the average body weight in the Tanta G-1 line was 1068.93 grams versus 551.25 grams in the Mamourah strain at the age of 8 weeks. This difference between the two lines was significant (P≤0.05). Body weight at sexual maturity was 3155.16 g,1525.00g for males and females in generation one, 3137.35g,1526.24g in generation two, and 3119.91g,1526.83g in generation 3 respectively for Tanta G- 1 and Mamourah chickens strain respectively. In the first generation age at sexual maturity for Tanta G- 1 was 172 days, while it was 157 days for the Mamourah strain. The weight of the first egg weight was (45.46g) for Tanta G- 1, while it was 34.84g for the Mamourah strain (34.84g). The overall mean fertility percentage for Tanta G-1 female egg was 87.92 %, while it was 88.94 % for the Mamourah strain and the difference was significantly different (P≤0.05). The overall mean hatchability percentage was 76.15% and 75.03%, for Mamourah and Tanta G- 1 line respectively.
