Abstract:
The experiment was conducted using 180 fertilized eggs to study the effect of egg weight on the productive performance of quail chicks, as the eggs were distributed in three weight treatments : the first treatment T1ws contained small eggs <10 g, the second treatment T2wm contained eggs of an average weight of 10-12 g, the third treatment T3wb contained large eggs >12 g. The eggs were incubated in perfect conditions for 16 days. The results of the study found that there was a significant effect of egg weight in the productive performance of birds. Low-weight eggs resulted birds whose amount of feed was lower and significantly than the rest of the groups studied (423.5g), treatment T2wm (495.6 g) and the value of FCR was high (2.19). The results showed a significant difference in the age of females reaching the peak of egg production between the three treatments. Treatments (t2wm, T3wb) reached to peak of egg production in the thirteenth week, while T1ws treatment reached in the fourteenth week.
