Effect of incubation temperature on hatching characteristics and post-hatch performance in broiler chickens

Popis výsledku v původním jazyce

This study was conducted to elucidate the embryonic development, hatchability, and post-hatch growth performance of broiler chickens when eggs were incubated during first 36 hours at 2 different temperatures. Totally, 1200 hatching eggs produced by Ross 308 broiler breeders (55 weeks of age) had been stored for 4 days. The hatching eggs were divided into 2 groups. Control group (CG) was incubated first 36 hours at 38.22 oC (100.8 oF). Experimental group (EG) was incubated first 36 hours at 39.17 oC (102.5 oF). Although the hatchability of fertilized eggs was higher in CG, as with fertility, there was no significant difference between groups. Differences in mean embryonic mortality and late embryonic mortality were statistically significant (P&lt;0.05). In CG the mean middle embryonic mortality was 1.76% and the mean late mortality 2.47%, while in EG the mean middle embryonic mortality was 0.71% and the mean late embryonic mortality 4.17%. However, during the whole experimental period, in EG the average weight was statistically significantly (P&lt;0.05) below the weight of CG, in uniformity, feed intake and feed conversion there was not statistically significant (P&gt;0.05) difference. Temperature setting change in hatching machine at first 36 hours of incubation from standard 100.8 oF to 102.5 oF had negative impact on hatchability and post-hatch growth.
