The number of wild quail has dramatically reduced in China and reached a state of endangerment with the deterioration of the environment in recent years. In this study, we examined the ecological behaviors of quails in the cage to determine the differentiation level between wild Japanese quail and domestic quail, to detect the relationship between quail behavior and evolutionary differentiation...

an experiment was conducted to study the effects of soybean, linseed and sunflower oil (various sources of fatty acids) with and without l-carnitine supplements (0 and 50 mg kg-1) on performance, blood biochemical parameters and carcass traits of japanese quail. one hundred and ninety-two of 7-day old female japanese quail were randomly assigned to 6 dietary treatments with 4 replicates and fed...

The aim of the performed investigations was to compare eggs of Japanese quail layers of different weights with regard to their shape, selected traits of the content following various times of their storage as well as the results of hatchability and body weight of one-day old chicks. Hatching eggs were divided into four groups: group S – up to 10.50 g, group M – from 10.51 to 11.50 g, group L – ...

A total number of 66 day old Japanese quail chicks divided into 2 treatment groups (33 in each treatment) with 3 replications in each having 11 birds (male, 5 and female, 6) were reared on floor and in cage system for a period of 5 weeks to know the effect of rearing system on growth performance and carcass characteristics. At the age of 35 days, average body weight and feed intake were 102.15 ...

background: lead is the oldest known toxic metal, physiologically and biologically harmful to living creatures. this study aimed to evaluate the lead accumulation in the liver and breast muscles of japanese quail (coturnix japonica) and to compare concentrations in both sexes and its effect on blood biochemical factors. methods: twenty-four young farm japanese quails (25 day old) prepared from ...

The present  study  was carried out to investigate the polymorphism of intron 3 to exon 3 of prolactin gene containing 24 bpindel at nucleotide position (np)  358 and its association with some reproductive traits in Japanese quail. These traits consisted of weight (WSM) and age at sexual maturity (ASM), mean egg weight at 2nd, 4th, 6th, and 2-6th weeks (MEW), and the number of eggs during the 2...

This study aimed to evaluate the lead accumulation in the liver and breast muscles of Japanese quail (Coturnix japonica) and to compare concentrations in both sexes and its effect on blood biochemical factors. Methods: Twenty-four young farm Japanese quails (25 day old) prepared fr...

The objective of this study was to identify the quantitative trait loci (QTL) affecting carcass traits on chromosome 1 in Japanese quail. The populations comprised of 422 progeny in 9 half-sib families. Phenotypic data on carcass weight, carcass parts, and the internal organs were collected on 422 progeny. Nine half-sib families were genotyped for 8 microsatellite markers covering chromosomes 1...
