Fragments of quail wing bud containing myogenic cells of somitic origin and fragments of quail sphlanchopleural tissue were introduced into the interior of the wing bud of fowl embryo hosts. No movement of graft into host tissue occurred in the control, but myogenic cells from the quail wing bud fragments underwent long migrations in an apical direction to become incorporated in the developing ...

We describe here conditions allowing the selective growth in culture of embryonic capillary endothelial cells from quail yolk sac. Such cultures were set up to characterize an antigen present on the endothelial cell surface and to study whether it was secreted in the culture medium. This antigen, MB1, was previously evidenced by a monoclonal antibody raised to quail IgM heavy chain. It is prese...

A 2×2×2 factorial design experiment was carried out with two levels of protein (20 and 22%), two levels of lysine (1.05 and 1.15%) and two levels of total sulfur amino acids (TSAA) (0.8 and 0.9%) to investigate their effect on growth performance and carcass characteristics of growing Japanese quail. A total number of 408 unsexed one week old Japanese quail chicks were randomly distributed into ...

HemoglobIn ontogenic changes have been studied In chimeras composed of a quaIl embryo grafted on a chIck yolk sac. From the blood of such chlmeras, quaIl erythrocytes are separated from chIck by means of a specific Immune hemolytlc technIque, thus yielding two populations of red cells, one derIving from yolk sac stem cells and the other from intraembryonlc stem cells. Both populations comprIse ...

Evaluation of Different Level Dietary Chromium Picolinate on Performance, Egg Quality, Some Blood Metabolite in Japanese Laying Quail

Introduction A number of methods have been investigated to improve the hatchability of eggs stored for more than seven days. Recently, it was reported that pre-heating of poultry eggs before storage resulted in more live chicks and a lower level of embryonic mortality compared to eggs that were not heated [2, 6, 7, 10]. However, no previously conducted research has tested pre-incubation storage...

the present research was conducted to estimate the dietary lysine (lys) requirement of growing female quail base on performance and carcass constitutes at 24 to 42 d of age. a dose-response diet mainly based on corn, corn gluten and soybean meal was used. lys content was minimized in dose-response diet (10 g/kg) while assuring the minimum levels of all other essential amino acids in a manner th...

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...

Based on detection of hepatic residues, scavenging and predatory non-target raptors are widely exposed to second generation anticoagulant rodenticides (SGARs). A small proportion, generally <10%, of tested birds are diagnosed as acutely poisoned. Little is known, however, of sub-lethal effects of SGARs, such as interaction of clotting capacity with traumatic injury. Assessment of coagulation fu...

Ecological niche models (ENMs) have increasingly been used to estimate the potential effects of climate change on species' distributions worldwide. Recently, predictions of species abundance have also been obtained with such models, though knowledge about the climatic variables affecting species abundance is often lacking. To address this, we used a well-studied guild (temperate North American ...
