an experiment was carried out to develop and evaluate a semi-purified diet suitable for fiber related studies without negative impacts on performance, serum biochemistry and intestinal morphology of growing japanese quails. total of 144 japanese quail chicks were used in a factorial arrangement using completely randomized design with 6 treatments, 4 replicates of 6 quails in each replicate. the...

This experiment aimed to study the effect of dietary thyme and turmeric essential oils supplementation on growth performance, nutrient utilization economics Japanese quails. For this purpose, a total 180 six-day-old quail chicks were randomly assigned into five different treatment groups, each with three replicates (12 birds per replicate). The was conducted for 35 days. Different groups quails...

Aim of the present study was the comparative evaluation of the effect of ground oregano, anise and olive leaves as feed additives on performance and some egg quality characteristics of laying Japanese quails. A total of 189 Coturnix japonica quails (126 females and 63 males), 149 days old, were randomly allocated into seven equal groups with three subgroups of 9 birds each (6 females and 3 male...

Finding a given location can be based on a variety of strategies, for example on the estimation of spatial relations between landmarks, called spatial orientation. In galliform birds, spatial orientation has been demonstrated convincingly in very young domestic chicks. We wanted to know whether adult Japanese quails (Coturnix coturnix japonica) without food deprivation are also able to use spat...

To assess the effect of single low energy-low protein diet with normally required calorie: protein ratio against normal dietary NRC 1994 requirements in summer season on laying and reproductive state of Japanese quails. Forty-two days old, 60 adult and sexed Japanese quails were divided into two equal groups, 5 replicates, and 6 birds each with a sex ratio 1:5. A laying and reproductive trial e...

Most laboratory studies of mate choice use affiliation as a surrogate measure for actual choice of a partner for copulation. In a series of recent studies using affiliation as a dependent variable, we showed that the tendency of both male and female Japanese quail to affiliate with members of the opposite sex is profoundly affected by seeing them mate with others: female quails show an increase...

Understanding the mechanisms that lead organisms to be separated into distinct species remains a challenge in evolutionary biology. Interspecific hybridization, which results from incomplete reproductive isolation, is a useful tool to investigate such mechanisms. In birds, interspecific hybridization is relatively frequent, despite the fact that closed species exhibit morphological and behaviou...

The study is to evaluate the effect of age and sex on serological indices of Japanese quail (Coturnix coturnix japonica) reared in derived savanna area of Nigeria. A total of 200 quails comprising 100 each of male and female were selected for this study. Fifteen each of the males and females quails were randomly selected at each week of 6, 7, 8, 9, 10 and 11 respectively. Data were obtained on ...

The purpose of this study was to characterize Eimeria bateri oocysts and to evaluate the aflatoxin effect in the morphometry of sporulated oocysts in Japanese quails infected naturally. Of a total of 50 quails naturally infected by E. bateri were randomly divided into two groups with 25 birds each. In one of them, quails were orally administered with aflatoxin in dose of 0.04 mg/kg body weight ...
