Effects of Relative Humidity During Last Stage of Incubation on Hatching Traits and Performance of Broiler From Old and Young Breeder Flocks Eggs

Abstract

Incubating eggs produced by two commercial flocks (26 and 52 wk) of Ross308 broiler breeders. Broiler hatching eggs were subjected to one RH (relative humidity) condition from 0 to 16 d of incubation and switched one of three different RH conditions (48, 58, and 68 %) from 16 d to 19.5 d of incubation. From 19.5 d to pull time RH conditions were switched to 75 % for all groups. Llate term deaths, hatchability of fertile eggs, hatch time and some organ weights at hatch and post hatch per-formance of the groups were measured. Hatchability was depressed when eggs exposed to 58 and 68 % RH from hens at 26 wk old compared to that of 52 wks old group. However, hatchability of the young group was improved when the eggs exposed to 48 % RH during the same period. Moreover, the hatchability also decreased in eggs from 26 wk old group irrespective of RH conditions old compared to that of 52 wks old group. As generally the embryos from hens at 52 wk old tended to early hatching compared to other treatment group. Chick body weight at hatch decreased in eggs from old group. Percent yolk weight was high in embryos from 26 wk old parents at hatch. Percent liver and heart weights depressed in chicks from 26 wk old parents. The effects of RH on hatching results and organ weights were not consistent and varied with breeder age. There were found no significant differences be-tween the groups for post hatch performance.
