an experiment was conducted to study the effect of metabolizable energy (me) and protein of japanese quails diets on offspring performance and antibody production against sheep red blood cell (srbc). a total of 432 japanese quails (13 week-old) were divided into nine treatments. each treatment comprised four replicates of twelve birds (9 female and 3 male). nine diets including three levels of ...

the effect of genotype, sex and hatch on carcass traits and physical characteristics of eggs was investigated in the japanese quail. two strains of japanese quails including the white (p1) and wild (p2) genotypes were chosen as the parental generation and crossed reciprocally (10 single-pair mating) to create the f1 progeny. the f1 birds (27 males and 81 females) were mated randomly to produce ...

The ex vivo culture of avian embryos is a technique for the long-term culturing of embryos outside of their own shell and shell membrane. It allows easy access to the developing embryos and embryo manipulation. The two-step system is widely applied when the culture is performed after oviposition. Japanese quail as well as bobwhite quail are used as models for avian safety assessment as recommen...

brachiocephalic arteries in quails are large arteries which are arising separately from the aortic arch. the aim of the present study was to determine the histomorphometric aspects of brachiocephalic arteries in the japanese quail. the different layers of the brachiocephalic artery were studied quantitatively in 10, 20 and 60 days-old japanese quail; (n = 6) and both sexes. luminal diameter, th...

the current study was conducted to investigate the effect of short-term divergent selection on the shape growth curve in different lines of japanese quail. the quail lines utilized in this study were two divergently selected for high (hw) and low (lw) 4-wk body weight during 7 generation and also a control line (c). the richard function parameters were used to describe growth curves of differen...

Precocial avian hatchlings are typically highly social and show strong species-typical preferences for the maternal calls of their own species. The influence of social contingencies on the acquisition of species-specific preferences has, however, largely been neglected. We found that exposing bobwhite (BW) quail chicks to a Japanese quail (JQ) call contingent on their own vocalizations for 5 mi...

background: the aim of the present study was to find the effects of cadmium (cd) on japanese quail on the role of an animal model in order to understand the toxicity of cd in creatures presented, within the environment. methods: one hundred 30-day-old male japanese quails were equally divided into the control group and cd group. the control group received no cd while the cd group was given form...
