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...

The present study is aimed to investigate changes in caecal wall histology of quails, during prepubertal and pubertal periods. To this end, forty quails at the ages of 10, 20, 30 (prepuberty) and 40 (puberty) days were slaughtered (10 birds in each sampling time) and histological sections from proximal, middle and distal parts of caeca were prepared and stained with H&E. It was observed that in...

The occurrence of caecal nematode, Subulura brumpti has become more common in quails being maintained in commercial farms in Tamil Nadu, India. Two trials were carried out to study the biology and pathology of S. brumpti in quails. In the first trial, eight grower quails were divided into two groups (T1 and T2) comprising of four birds each. The birds belonged to the group T1 was infected with ...

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 ...

We report an unusual case of rhabdomyolysis due to coturnism (food poisoning caused by eating quails). The patient's clinical course is described, and possible pathogenetic mechanisms of this syndrome are briefly discussed.

Background: The growth of birds is a function both genetics and environment involving change leading into improvement in weight, shape, size, volume, etc. Study important non-genetic factors view formulating future selection breeding strategies different poultry species. Methods: present study was done on 1246 numbers Japanese Quails (Coturnix coturnix japonica) two strains i.e., black white di...

This experiment was undertaken to assess the influence of thyme (Thymus vulgaris) and turmeric (Curcuma longa) essential oils on hematobiochemical parameters Japanese quails. One hundred eighty, 6-day old quail chicks were subjected five weeks trial. Quail distributed at random into dietary treatment groups each with three replicates 12 quails per treatment. Quails T0 group fed diet without (Ba...

Rabbit antisera were prepared against crystalline chicken lysozyme and characterized by immunodiffusion, immunoelectrophoresis, inhibition of enzyme activity, and quantitative micro-complement fixation. Lysozyme was purified by Sephadex G-75 chromatography from the egg whites of 17 species of birds in the order Galliformes and was tested for reactivity with anti-chicken lysozyme. The chicken an...
