This study was conducted to determine the effects of dietary supplementation olive leaf extract (OLE), eggshell with membrane (ESM), and ESM that absorbed OLE (OLE+ESM) on performance, egg quality, biochemical, bone parameters in laying Japanese quail. A total 112 quail, being 45-day-old, were divided into 4 groups replicates. The quail fed four diets: i) basal diet ii) supplemented 400 ppm iii...

One hundred and eighty 7-week-old laying quail were fed various diets over a 12-week period. The diets included a control diet (without essential oil mixture (EOM) or antibiotics (ANTs)), a basal diet including EOM (24 mg/kg feed), and a basal diet including an ANT (avilamycin, 10 mg/kg feed). Each treatment comprised 4 replications with 4 cages (15 quail per cage), amounting to 60 quail per tr...

$ EVERAL releases of Japanese Quail (Coturnix coturnix japonica) have been l__. made in the United States since 1956. This attempted stocking appears to have been unsuccessful, as were releases of this form and C. c. coturnix made more than fifty years ago (Phillips, 1928). However, recent interest in the bird has pointed up its qualities as an experimental animal. As Padgett and Ivey (1959) po...

The avian oviduct is subdivided into five regions according to its function in egg formation and histological features. They are the infundibulum, albumen secreting region (magnum), isthmus, shell gland (uterus), and vagina. The epithelium of these regions consists of ciliated and nonciliated cells. In addition to secretion granules, specific to each region, in the non-ciliated cells, considera...

Individual phenotypic characteristics of many species are influenced by non-genetic maternal effects. Female birds can influence the development of their offspring before birth via the yolk steroid content of their eggs. We investigated this prenatal maternal effect by analysing the influence of laying females' social environment on their eggs' hormonal content and on their offspring's developm...

A 10 week feeding trial was carried out to evaluate the replacement value of hatchery wastes for fish meal in the diet of laying Japanese quail (Coturnix coturnix japonica). 108 female Japanese quails (36 per treatment) were randomly allocated into 3 dietary treatments A, B and C which are fish meal (FM), whole hatchery waste meal (WHWM) and shelless hatchery waste meal (SHWM) based diets respe...

The present  study  was carried out to investigate the polymorphism of intron 3 to exon 3 of prolactin gene containing 24 bpindel at nucleotide position (np)  358 and its association with some reproductive traits in Japanese quail. These traits consisted of weight (WSM) and age at sexual maturity (ASM), mean egg weight at 2nd, 4th, 6th, and 2-6th weeks (MEW), and the number of eggs during the 2...
