In: Zagazig Journal of Agricultural Research 2006.v.33(3)Summary: A total number of 480 unsexed one week old Japanese quail chicks for growing period and 96 layers (64 females plus 32 males) were used in the 1st generation. While, in the 2nd generation 416 unsexed one week old chicks for growing period and 96 layers (64 females plus 32 males) were used. This work was conducted to study the effect of dietary aflatoxin B1 (AFB1) at levels (0.0, 1.5, 3.0 and 4.5 ppm) on Japanese quail performance, during growing and laying periods for two generations. The live body weight (LBW), egg number (EN), egg weight (EW), some external and internal traits for egg quality were significantly (P :0: 0.01) lower and delayed sexual maturity with 4.5 ppm than 3.0, 1.5 and 0.0 ppm levels, respectively in both generations. Heritability estimates based on sire component of variance (h5s) for LBW at different ages ranged between moderated (0.209) to high (0.825). While, I( for age, LBW and egg weight at sexual maturity were 1.05, 0.951 and 0.792, respectively. hs5 for EN and EW at different ages were ranged between 0.386-1.333, while egg quality traits were ranged between 0.065-0.755.
