The present study describes clinical, virological, histopathological, immunohistochemical and electron microscopic findings of pox infection encountered in a quail flock. Lesions consisted of single or multiple nodules with a crust in variable size of gray to yellow or dark brown discoloration on the comb, eyelids, and the other poorly feathered areas of the body. Histopathological changes cons...

To determinate the effect of chromium-methionine level in diet on hatchability of Japanese quail in dry tropic weather under temperaturecontrolled in summer season, a completely randomized design experiment was conducted. Thousand two hundred eighty Japanese quail (960 females and 320 males), they were divided in 160 groups of eight (six females and two males), and were allocated in wire cages ...

Since cinnamon has vitamins and minerals in addition to antioxidants compounds in its chemical composition studies have shown the potential of cinnamon supplementation on some important characteristics in the performance of birds. Thus, this study was conducted under the hypothesis that the inclusion of cinnamon in the laying quail diet could influence the performance of the birds through the e...

In this study, ventricular wall volume of female and male quails was investigated stereologically. Six females six males were used in study. All the animals perfused. After perfusion, kept 10% formaldehyde solution. Afterwards, chests cut their hearts resected. Ventricles separated. Specific ratio tissue samples obtained from each ventricle. The 5-µm thick by using a microtome. Sequentially, 10...

The quail raising in Brazil has increased through the last years and the incubation procedures are important to maintenance and improvement of quail egg production. To obtain a sufficient number of eggs to fill an incubator, eggs are usually accumulated in storage over a period from 1 day up to 3 weeks before incubation. The objective of this research was to verify the effect of egg storage on ...

We investigated the role of 5-HT2C receptors and serotonergic transmission in the feeding behavior control of quails. Administration of serotonin releaser, fenfluramine (FEN) and 5-HT2C agonists, mCPP and MK212, 1.0 and 3.3 mg/Kg induced significant inhibition of food intake in previously fasted fowls (0.71 +/- 0.18 g and 0.47 +/- 0.2 g; 0.49 +/- 0.22 g and 0.48 +/- 0.29 g; 0.82 +/- 0.13 g and ...

This study examined the comparative utilization of 30% inclusion levels of three vegetable protein sources [Groundnut Cake (GNC); Soybean Meal (SBM) and Cotton Seed Cake (CSC)] in the diets of growing and laying Japanese quails. The findings showed no significant variations (P>0.05) on feed intake, weight gain and feed/gain ratio during the growing period among the vegetable protein sources fed...

We investigated participation of the brain serotonergic system in food intake control by using oral and systemic administration of serotonin precursors in quails (Coturnix japonica). Dietary supplemental tryptophan (0.1-50.0 g/kg) provoked a dose-dependent inhibition of food intake during a 5-h observation period, which persisted up to 24 h for doses of 30.0 and 50.0 g/kg. Normally fed and fast...

Apoptotic signaling was examined in the patagialis (PAT) muscles of young adult and old quail. One wing was loaded for 14 days to induce hypertrophy and then unloaded for 7 or 14 days to induce muscle atrophy. Although the nuclear Id2 protein content was not different between unloaded and control muscles in either age group, cytoplasmic Id2 protein content of unloaded muscles was higher than th...

AIM The aim was to study the effect of Aloe vera and clove powder supplementation on carcass characteristics, composition and serum enzymes of Japanese quails. MATERIALS AND METHODS The study was conducted on 120-day-old Japanese quails, which were randomly divided into four treatment groups viz. T1-control, T2-0.5% A. vera, T3-0.5% clove, and T4-(0.25% A. vera + 0.25% clove) powder, each hav...
