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 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...

this study aimed to evaluate the antioxidant property of chavir plant on japanese quail intoxicated with carbon tetrachloride (ccl4). eighty, one-d-old japanese quail chicks were randomly allotted to 4 treatments with 4 replicates and 5 chicks in each, using completely randomized design with 2×2 factorial arrangements including 2 levels of chavir powder (0 and 1.5 percent) and ccl4 (0 and 1 ml/...

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...

In present study, two trials had been conducted to evaluate the effects of Spirulina platensis (SP) on growth performance, carcass characteristics, egg quantity and quality traits, and immunity response of Japanese quails. In trial 1, a total number of 180 one-day-old Japanese quails were randomly assigned into 6 groups, 3 replicates with 10 quail chicks per replicate. Experimental die...

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...

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...

A study was conducted to determine the effects of EM supplied in drinking water and feed on growth, egg production and waste characteristics of Japanese quail. The effect of EM on the growth of 1,000 day-old quail was assessed using a completely randomized design with four treatments: a control; EM added in drinking water at 1:5,000; EM (in the form of fermented compost or bokashi) added in fee...

This study was undertaken to assess the production systems, prospects and challenges of quail farming in three (3) ecological zones (Rainforest, Transitional Guinea Savannah) Ghana. Sixty (60) farmers were purposefully sampled for using snowball sampling technique. Data gathered through interviews with aid structured questionnaire analysed SPSS 22.0. The results showed that more males (86.7%) t...
