A study was carried out to determine the effect of crude protein level in diets on Serum Biochemical Indexes and Gastrointestinal Micro flora of yellow quails. Four diets with different crude protein levels 17.75%, 19.95%, 21.85%, 24.08% were used to feed 192 yellow quails during 50-day-old to 95-day-old in this experiment. The quails were randomly assigned to 4 groups by similar body weight, e...

In human bipedal walking, temporal changes in the elevation angle of the thigh, shank and foot segments covary to form a regular loop within a single plane in three-dimensional space. In this study, we quantified the planar covariation of limb elevation angles during bipedal locomotion in common quails to test whether the degree of planarity and the orientation of the covariance plane differ be...

The weekly liveweight gain, growing and stress parameters of quails bred using two different types of lighting for 6 weeks following hatching were examined in this study. The first type of lighting was 23 L:1 D, continuous lighting (CL), widely used in the commercial system and the second was a self-photoperiod (SP) system consisting of a continuously lit chamber and a dark chamber the quails c...

The common quail (Coturnix coturnix) is a popular game species for which restocking with farm-reared individuals is a common practice. In some areas, the number of released quails greatly surpasses the number of wild breeding common quail. However, common quail are difficult to raise in captivity and this casts suspicion about a possible hybrid origin of the farmed individuals from crosses with...

The influence of ascorbic acid administration via drinking water at a dose of 15 mg/l over a period of 7 days on the pharmacokinetics of oleandomycin in chickens, musk ducks and Japanese quails was investigated. After ascorbic acid oleandomycin elimination, half-life was longer. Oleandomycin bioavailability in chickens and quails after per os application was increased with ascorbic acid. Inters...

This experiment was conducted to evaluate the effects of different levels (0, 2 and 4%) of canola oil and 2 levels of heat (1 and 2 time heated) on blood biochemical parameters of Japanese quails. This study carried out in factorial (3×2) experiment based on completely randomized design with 360 of Japanese quails in 6 treatments and 3 replicate for 35 of day. In this study, blood biochemical p...

By sequence analysis in ten quails with acid maltase deficiency (AMD), we have identified the mutation in qgaa1 gene, but not in qgaa2 gene. No mutations were detected in either gaa gene in ten normal quails. AMD quails had a novel G deletion at nucleotide position 1639 in exon 7 in qgaa1 gene (designated 1639delG). This deletion causes a frameshift altering the amino acid sequence from positio...

The present study aimed to investigate the effects of different levels of dietary metabolizable energy (ME) and crude protein (CP) on performance and carcass characteristics of Japanese (Coturnix japonica) and Brown (Coturnix ypsilophorus) quails during a 42 d feeding trial. A total of 720 (360 per each species) one week-old quail chicks were randomly (by species) distributed between 72 cages a...

Toxic effects of Aflatoxin B1 on growth performance and humoral immune response against Newcastle disease Virus (NDV) vaccine were determined in Japanese quails. Quail chicks (n=300) were divided into five groups and each group was further sub-divided into two subgroups. One subgroup of each group was vaccinated with NDV vaccine to study the antibody response. Experimental diets were prepared b...

In this study, we investigate the effect of serotonin receptor 5-HT1A stimulation on the feeding behavior of quails (Coturnix japonica). The administration of 5-HT1A agonist, 8-OH-DPAT (0.05 to 5.0 mg/Kg) dose-dependently inhibited the food intake in normally fed quails. Greater inhibition was attained with 5.0 mg/kg (0.93 +/- 0.21 g vs. 5.83 +/- 0.25 g, P < 0.05, 2 h after food offer). A compa...
