Recombination of the epithelium and mesenchyme between quail anterior submaxillary gland (elongating type) and quail anterior lingual or mouse submaxillary gland (branching type) was effected in vitro to clarify whether the elongating morphogenesis was directed by the epithelial or the mesenchymal component. Quail anterior submaxillary epithelium recombined with quail anterior lingual or mouse ...

Recently, the requirements for quality and safety of poultry products have significantly increased, what has notably limited use antibiotics in feeding poultry. This is one reasons growing interest phytogenic feed additives. We conducted an experiment to determine influence Artemisia capillaris on young quail meat productivity. To carry out experiment, we formed five groups, each counting 100 h...

The present study was conducted to investigate the effects of dietary lysine (Lys) and sex on growing quail performance and immunity parameters. The six dietary Lys: 10, 11.5, 13.0 (NRC 1994 recommendation), 14.5, 16.0 and 17.5 gr/kg were provided. The other essential amino acids except lysine were provided to meet or exceed NRC 1994 recommendation for growing quail. This experiment was carried...

The present study makes an investigation into expression of genes related to cardiac development in chicken, quail and chicken-quail hybrids during the early stage of embryogenesis. Real-time PCR was used to detect mRNA expressions of Nkx2-5, GATA4 and TBX5 in the heart of chicken, quail and chicken-quail hybrids embryos during the 3rd to 7th days of incubation. Results showed that NKX2-5 mRNA ...

The ex vivo culture of avian embryos is a technique for the long-term culturing of embryos outside of their own shell and shell membrane. It allows easy access to the developing embryos and embryo manipulation. The two-step system is widely applied when the culture is performed after oviposition. Japanese quail as well as bobwhite quail are used as models for avian safety assessment as recommen...

Cultured quail myocytes were much more resistant to H2O2 toxicity than cultured mouse myocytes. The intracellular concentration of glutathione ([GSH]i) and the activity of gamma-glutamylcysteine synthetase (gamma-GCS) in quail heart cells were about five and three times higher, respectively, than in mouse heart cells, although catalase and glutathione peroxidase (GSHpx) activity was similar in ...

Animals perceiving repeated aversive events can become chronically stressed. Chronic activation of the hypothalamic-pituitary-adrenal (HPA) axis can have deleterious consequences on physiological parameters (e.g. BW, blood chemistry) and behaviour (e.g. emotional reactivity, stereotypies, cognition). Environmental enrichment (EE) can be a mean to reduce animal stress and to improve welfare. The...

As climate change is expected to worsen in the future, raising livestock animals used meat production with maximum efficiency warm conditions may become a necessity meet food needs. To this end, experiment was carried out determine quality properties of breast from different colored Japanese quails (Coturnix coturnix Japonica) grown under conditions. A total 100 were used, 25 each black, white,...
