an experiment was conducted to study the effect of metabolizable energy (me) and protein of japanese quails diets on offspring performance and antibody production against sheep red blood cell (srbc). a total of 432 japanese quails (13 week-old) were divided into nine treatments. each treatment comprised four replicates of twelve birds (9 female and 3 male). nine diets including three levels of ...

This study aimed to demonstrate the influence of the systemic administration of l-5-hydroxy-tryptophan (L-HTP) on the plasma levels of melatonin during the dark period in quails. Throughout daylight, the plasma levels of melatonin did not differ significantly, oscillating between 110.2 +/- 15.8 pg.mL(-1) and 157.4 +/- 34.8 pg.mL(-1), from 8 to 16 hours. L-HTP (25 mg.kg(-1), through the intracel...

The luminal epithelium of the oviduct (magnum) of laying quails is composed of ciliated cells and mucous cells. Ciliogenesis was observed in some of the mucous cells. Both centrioles of the diplosome migrate to the top of the cell, and one of them induces the formation of a rudimentary cilium. In some of the other cells, that are filled with mucous granules, the formation of basal bodies by an ...

Four young Bobwhite quails (Colinus virginianus) were submitted to the Veterinary Diagnostic and Investigational Laboratory of The University of Georgia for necropsy. The quails were from a flock which had a history of anorexia, weakness, diarrhea, dehydration, weight loss and acute death. The total number of mortalities within two weeks was 80 out of approximately 900 birds. Multi focal sub-se...

This study was carried out to determine the effects of supplementation ground fennel quail rations on egg production, slaughter, intestinal parasites, and semen quality. For this purpose, 48 female 24 male quails were used in study. The experimental groups consisted control group with basal feed + 0% fennel, GF1, GF2, GF4 fennel-supplemented by 1%, 2%, 4% respectively, also each designed pairs....

We evaluated messenger RNA (mRNA) expression of the growth-hormone (GHR) and insulin-like growth factor (IGF-1) genes in 28-day-old Japanese meat quails fed diets containing 0, 8, or 12% dietary glycerol in substitution of corn. Total RNA was extracted from the breast muscle and the DNA was amplified with specific primers using real-time PCR. Feed conversion ratio and feed intake were evaluated...

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...

This study was undertaken to determine the effects of storage period and egg weight of hatching eggs of Japanese quails on fertility, hatchability results. Eggs were obtained 150 females quails, all at 15 weeks of age. A total of 1942 hatching eggs were separated into 3 groups as light-weight (9.50-10.50 g), medium-weight (10.5111.50 g), and heavy-weight (11.51-12.50 g). Based on storage period...

The aim of this study was to investigate the effects of different levels of cadmium supplementation (0, 5, 10, 20, 40 and 80 mg/kg) in the diet on performance, egg quality, tibia biomechanical properties and eggshell and bone mineral contents in laying quails. In this 10-week trial, a total of 96 laying quails, aged 21 weeks, were randomly distributed among six experimental groups. Each experim...

YAYLA, S., N. N. KAMILOGLU, A. KAMILOGLU, I. OZAYDIN and C. S. ERMUTLU, 2015. Comparison of the effects of intramuscular and intraosseal administration of detomidine/ ketamine combination for general anaesthesia in quails (Coturnix coturnix japonica). Bulg. J. Agric. Sci., 21: 220-224 The aim of this study was to evaluate the quality of anesthesia and heart rate (HR), respiratory rate (RR) and ...
