The current study was conducted to investigate the effects of genetic and non-genetic factors on body weight and carcass traits of Japanese quails. Two strains of Japanese quail (150 wild quails and 150 white quails) were used as base population. Four mating groups were used to produce progenies: wild male × wild female, white male × wild female, wild male × white female and white male × white ...

Escherichia coli isolates were cultured from diseased Japanese quail and their environment. Of 31 E. coli isolates, 11 were cultured from heart blood of dead Japanese quail and 20 were from dead-in-shell embryos, fluff samples, and footbath and drinking water samples. All E. coli isolates were moderately positive on the Congo red binder test and 14 out of 31 isolates produced hemolysis on sheep...

Fitting Growth Curve in Japanese quail (Coturnix Coturnix Japonica) using Nonlinear and Mixed-Effects Models

The main objective of this study was to elucidate the effect of short- term exposure of Japanese quail eggs to acute high incubation temperature on embryonic development and on the ability of post- hatched chicks to cope with subsequent heat stress conditions during the growing period. A total of 998 Japanese quail eggs were divided into two groups, the first group (470 eggs) was maintained at ...

the present study was conducted to evaluate the effect of different levels of organic selenium and vitamin e on performance and meat quality in japanese quail. four hundred eighty quails were carried out in a completely randomized design with two levels of organic selenium (0.2 and 0.4 mg/kg) and three levels of vitamin e (18, 90 and 180 mg/kg). four replicates with 20 quails were allocated to ...

in the present research, divergent selection for japanese quail body weight at four and five weeks of age was performed in five generations to estimate the response to selection and realized heritability. the average body weight was significantly (p
