Abstract:
A total of 3000 eggs; 750 eggs from each breed namely Barred Plymouth Rock (BPR),White Leghorn (WLH), Rhode Island Red (RIR) and White Rock (WR) were collected in 3 batches following AI from individually caged hens and were hatched to compare hatching parameters among breeds. The different hatchability traits of hen of different breeds; BPR, WLH, RIR and WR were compared. Hatching egg weight had no significant (P>0.05) difference among 4 genotypes. Fertility was highest in WLH, intermediate in WR and lowest and similar in BPR and RIR (P<0.01) with differences of fertility among 3 batches (P<0.01). Breed had little effect on hatchability of fertile eggs (P>0.05), but it differed among batches (P<0.01). Hatchability on total eggs was highest in WLH, intermediate in BPR and WR and lowest in RIR (P<0.05) and having also differences among batches (P<0.01). No significant (P>0.05) difference in dead in germs (DG) and dead in shell (DS) were found attributable to genotype, but DG and DS differed significantly(P<0.01) among 3 batches. Breed and batch had little effect on normal chicks and abnormal chicks hatched (P>0.05). Chick weight at hatching was highest (P<0.05) and similar in BPR (38.95 g) and WLH (38.96 g), intermediate in RIR (38.50 g) and lowest in WR (38.13 g). Batch had little effect on chick weight. Percent chick weight was found highest (P<0.01) in BPR (67.21%), intermediate in RIR (65.96%) and lowest and similar in WLH (65.17%) and WR (65.46%) without significant (P>0.05) difference in batches. There were some correlations among different hatchability traits depending on genotype within breed. The correlations were more profound among WLH. It was clear that chick weight as percent of egg weight was not just a function of egg weight, but also genotype played an important role favouring the heavier breeds.
