Two experiments were conducted to evaluate the effect of stocking density on growing-meat quail performance (experiment I) and the effect of dietary crude protein (CP) levels and stocking density on growth performance, nutrient retention, blood metabolites, and carcass weight of growing-meat quails under high ambient temperature (experiment II). Three hundred and eighty male growing-meat quails...

this study has been carried out to investigate the effect of short-term divergent selection for 4-wk body weight on growth curve parameters and carcass components in japanese quail. quail lines utilized were two divergently selected for high (hw) and low (lw) 4-wk body weight (bw) as well as a line as control (c). the results of the study indicated that quails in hw line had heavier bw than tho...

the purpose of this study was to investigate the hypothesis weather the combination of lead acetate and deltamethrin can enhance avian toxic effects produced by lead exposure only. overall, 48 japanese quails, coturnix coturnix japonica (15 day old) were randomly divided into 4 experimental groups of 12 birds each and sex ratio of 1:1. experimental groups consisted of control japanese quails, b...

The hormonal control of ciliogenesis and transformation of mucous cells was studied in the oviduct (magnum) of ovariectomized quails. Estradiol benzoate induces ciliogenesis with doses varying from 10 mug/day to 100 mug/day after 6 days of treatment. With 100 mug/day, differentiation of some mucous cells is also induced as well as the formation of transitory "mixed cells" which are in the proce...

AIM The growth promoting effect of the blue-green filamentous alga Spirulina platensis (SP) was observed on meat type Japanese quail with antibiotic growth promoter alternative and immune enhancing power. MATERIALS AND METHODS This study was conducted on 180 Japanese quail chicks for 4 weeks to find out the effect of diet type (vegetarian protein diet [VPD] and fish meal protein diet [FMPD])-...

The purpose of this study was to genotypically characterize and phylogenetically analyze the 18S rDNA sequences of Cryptosporidium obtained from poultry in Brazil. Fecal samples were obtained from ducks, chicks and quails sold in popular markets. DNA was isolated from Cryptosporidium positive feces, and 18S subunit rDNA was amplified and processed using nested-polymerase chain reaction (PCR). T...

The widely used atrazine has been reported to exhibit extensive ecological hazards. Due to the biological accumulation, atrazine elicits widespread toxic effects on different organisms. However, true proof for the mechanism of atrazine-induced toxicity is lacking. To determine the potential mechanism by which atrazine exerted toxic effects, quails were treated with atrazine (0, 50, 250 and 500 ...

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...
