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...

Colibacillosis caused by avian pathogenic Escherichia coli (APEC) is an economic threat to the poultry industry throughout the world. Some of the virulence genes may enhance the ability of E. coli isolates to grow in the tissues of broilers. The APEC strains are assigned to a few distinct phylogenetic groups. The purpose of the present study was to detect the virulence genes a...

the goal of this experiment was to investigating of effects of different levels of nano chromium (n-cr) in diet on egg quality and blood chromium content of japanese quail. two hundred and forty laying japanese quail (45 day old) were randomly distributed to 20 experimental unit with 12 birds in cage pens of 40 × 80 cm. experimental treatments include: 1) control national research council (nrc,...

this study was conducted to investigate the effects of artichoke powder on performance and immune function of japanese quails poisoned with carbon tetrachloride (ccl4). one hundred meat type (1-d-old) quails were assigned randomly to 4 treatment groups (n=25). treatment groups included with the study were: 1) control group (without artichoke supplementation or ccl4 administration, 2) group with...

this study evaluated the effects of artichoke leaf powder on growth performance and physicochemical properties of japanese quailfrozen meat after 3 monthstorage. a total of 240 japanese quail chicks (1 d old) were raised over a 42-d experimental period. the experiment was performed as a completely randomized design with 4 replicates of 15 quails in each, using a 4 × 2 factorial arrangement with...

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...

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 ...
