Effect of Feeding Time on Laying and Reproductive Performance of Pharaoh Quail (Coturnix coturnix Pharaoh) Housed in Different Cage Systems
Metin Petek
A total of 120 male and 240 female quail (Coturnix coturnix Pharaoh) were used to determine the effect of feeding time on laying and reproductive performance of Pharaoh quail. They were fed ad libitum between 09:00 to 17:00 or full day, daily. Each female-male pair was housed in multiple-bird cages and colony cages. Initial and final body weight, quail-day egg production, feed consumption per egg and mortality were measured to determine laying performance of breeders. A total of 960 eggs were used to determine reproductive performance of quail in each treatment group. Eggs were incubated in a commercial setter and hatcher in standard conditions. Embryonic mortality, apparent fertility, hatchability of total and fertile eggs were calculated to determine the reproductive performance. Results indicated that feeding between 09:00 to 17:00 h reduced final body weight and egg production (p<0.001, p<0.001). Whereas, limited time of feeding improved hatchability of total (p<0.001) and fertile eggs (p<0.001) and reduced embryonic mortality (p<0.001) when compared with the effects of feeding full day. It was found that there were no significant differences for the egg production of quail housed in different cage systems. Quail caged in multiple-bird cages consumed less feed (p<0.01) compared to quail housed in colony cages. There were significant differences for the mortality (p<0.05), hatchability of total (p<0.001) and fertile eggs (p<0.001), and embryonic mortality (p<0.001) during the incubation due to main effect of cage systems. There were significant cage systems횞feeding time interactions for hatchability of total and fertile eggs and embryonic mortality (p<0.001). As a conclusion; feeding from 09:00 to 17:00 reduced laying performance of quail and improved the reproductive traits compared to full day feeding of quail breeders. But, further investigations are needed to determine the optimum length of feeding time and egg production of breeders in quail fed limited time must be evaluated in comparison with its beneficial or detrimental effects.
