This study was carried out to identify the effect of the egg shape index on the hatchability, performance, and carcass yield of Japanese quails (Coturnix coturnix Japonica). Eggs were incubated in three groups, according to three different egg shape index ( , and the results showed that females were heavier than males (p<0.05; p<0.01; p<0.001, respectively).The effect of egg shape index on slaughter weight (p<0.05), left leg weight (p<0.05), liver weight (p<0.01) and liver rate (p<0.01) was significant. Females were heavier at slaughter than males in the egg shape index groups SI-I (p<0.05), SI-II (p<0.05), and SI-III (p>0.05) (female/male: 296.87/283.80, 287.95/278.00 and 283.86/278.10 g, respectively). Males presented higher carcass yield in SI-I (p>0.05), SI-II (p<0.01) and SI-III (p<0.05) (female/male: 74.40/75.92, 74.50/76.44 and 74.80/76.42%) groups than females. Egg shape index had no effect on initial egg weight (IEW), shell blunt end weight (SBW), chick weight, shank length, growth performance or carcass traits, but egg shape indexwas correlated with egg length, egg width, and hatchability of fertile eggs (p<0.05).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
