Aim: The present study was designed to evaluate the safety of seabuckthorn (Hippophae rhamnoides L. Elaeagnaceae) leaves added in the diet of Japanese quail. Materials and Methods: A total of ninety quail chicks were randomly divided into 2 groups and fed a standard quail chick mash added with or without 2% SBT leaf powder (Group SX), and a standard quail chick mash (Group CX, control) for 21 d...

A 2×2×2 factorial design experiment was carried out with two levels of protein (20 and 22%), two levels of lysine (1.05 and 1.15%) and two levels of total sulfur amino acids (TSAA) (0.8 and 0.9%) to investigate their effect on growth performance and carcass characteristics of growing Japanese quail. A total number of 408 unsexed one week old Japanese quail chicks were randomly distributed into ...

The extracellular matrix surrounding avian oocytes, called the perivitelline membrane (PL), consists of at least two major glycoproteins, ZP3 and ZP1. Our previous study using Japanese quail had demonstrated that the PL obtained from the preovulatory follicles was incubated in vitro with spermatozoa, and perforations were observed. This result indicated that the PL might contain a constituent t...

the aim followed in the present research was to investigate the effect of nine generations of divergent selection on some reproductive and egg production traits in japanese quail. the results indicated that selection for 4-week body weight, increased the age at sexual maturity of hw and of lw lines, in comparison with control, for about 7 and 3 days, respectively (p

The effect of different housing conditions on body weight, weight gain, feed intake, water consumption, egg production, rectal temperature, hematocrit value and mortality rate were studied in Japanese quail. Three experimental groups: winter conditions (control), long day-light (lighted) and hot climate (heated) were used. A total of 195 quail chicks (65/group, 40 females and 25 males) were use...

To assess the genetic diversity of domestic Japanese quail (Coturnix japonica) populations, and their genetic relationships, we examined mitochondrial DNA (mtDNA) D-loop sequences and microsatellite markers for 19 Japanese quail populations. The populations included nine laboratory lines established in Japan (LWC, Quv, RWN, WE, AWE, AMRP, rb-TKP, NIES-L, and W), six meat-type quail lines reimpo...

The present investigation was designed to evaluate the role of yeast, Saccharomyces cerevisiae (SC) in the reduction of aflatoxicosis induced by aflatoxin B1 (AFB1) in Japanese quail. Sixty male quail were used and distributed into six groups. The first group received basal diet. The other five groups received the basal diet plus 0.5 mg AFB1/kg diet. Four of them received increasing levels of S...

An F2 Japanese quail population was developed by crossing two strains (wild and white) to map quantitative trait loci (QTL) for performance and carcass traits. A total of 472 F2 birds were reared and slaughtered at 42 days of age. Performance and carcass traits were measured on all of the F2 individuals. Parental (P0), F1 and F2 individuals were genotyped with 3 microsatellites from quail chrom...

Cryopreservation of testicular tissue can be used for ex situ conservation of male germplasm of avian species. The possibility of using vitrification and transplantation of testicular tissue for fertility preservation and recovery was tested in Japanese quail. Testes were removed from 1-wk-old Japanese quail; transfixed on acupuncture needles; equilibrated with dimethyl sulphoxide, ethylene gly...
