The Japanese quail is a widely used model organism for the study of embryonic development; however, anatomical resources are lacking. The Quail Anatomy Portal (QAP) provides 22 detailed three-dimensional (3D) models of quail embryos during development from embryonic day (E)1 to E15 generated using optical projection tomography. The 3D models provided can be virtually sectioned to investigate an...

the purpose of this study was to identify genomic regions of quantitative trait loci (qtl), affectingcarcass traits on chromosome 1 in an f2 population of japanese quail. for this purpose, a three-generationresource population was developed by using two distinct japanese quail strains, wild (meat type) andwhite (layer type). eight pairs of white and wild birds were crossed reciprocally and 34 f...

Bod a K., 1. I II e k, V. S abo: Concentrations o/Mineral Substances in the Tibiotarsus o/the Japanese Quail in Weightlessness. Acta vet. Bmo 1996, 65: 33-37. The concentrations of Ca, P, Mg, and Na were studied in the tibiotarsus of 17-day-old embryos of Japanese quail, in quail 2-4 days of post-embryonic development in the MIR orbital station, and in adult birds of both sexes exposed to 7 day...

This study was conducted to determine the effects of hempseed (H) on performance, carcass traits, and antioxidant activity in Japanese quail (Coturnix coturnix japonica). A total of 192 quail with seven-days old were divided into four experimental groups with four replicates. The treatments were; i) Control diet (C, no hempseed); ii) 5% hempseed in diet (H5); iii) 10% hempseed in diet (H10); an...

During normal development chick motoneurons have been shown to project selectively to appropriate muscles by responding to a series of cues, both specific and nonspecific, within the limb. We tested the ability of motoneurons from another avian species, the Japanese quail, to respond to these cues by transplanting chick limb buds onto quail embryos and quail limb buds onto chick embryos between...

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...

The effects of maternal androgens on fitness-related traits of offspring are generally assumed to be epigenetic adaptations to the environment that may be encountered by the next generation. Possible constraints of high yolk androgen transfer are still not understood, although a suppressed immune response in offspring is frequently considered. The aim of our study was to examine the innate immu...

ABSTR•CT.--Histological criteria indicate that thyroid glands are organized into follicles at about the same time of incubation in Japanese Quail (precocial) and Ringed Turtle Dove (altricial) embryos, but dove thyroids develop more slowly, are much smaller and are much less active than quail thyroids by the time of hatching. These results indicate thyroid readiness for participation in early e...

We have shown previously that after a focal female Japanese quail, Coturnix japonica, sees a conspecific male mating, the focal female's tendency to affiliate and to mate with that male is significantly increased. Here we describe two experiments demonstrating that a focal female quail that has seen a conspecific male mating subsequently shows an enhanced tendency to affiliate not only with tha...

The study aimed to compare the effects of different cryopreservation temperatures on mechanical properties and determine optimal temperature for bones in Japanese quail. Bone biomechanical tests are getting more attention but, fresh not always available testing have a limited lifespan. Cryopreservation biological specimens is often needed during tissue preparation testing. In study, tibiotarsi ...
