It has few breeding constraints. A phenotypic characterization study of the Japanese quail was carried out in southern Côte d’Ivoire to gain a better understanding of this bird. The study involved 298 individuals. The phenotypes were white, black, gray, and red. A total of 11 morphometric parameters were examined. Variables were significantly different between the phenotype and sex groups. The female quail was larger than the male quail. The quail was 20.77 and 4.10 cm long. The head was supported by a 5.89 cm-long neck. The tail was 3.61 cm long. The wing length was 10.42 cm, and the thigh diameter was 2.12 cm. The tarsus was 3.39 cm long and 0.61 cm in diameter. The average quail weight was 297.06 g. The quails in this study exhibit a high degree of morphological variation between individuals in terms of plumage. These results can help develop strategies for developing and genetically improving this short-cycle resource.展开更多

[ Method ] The high-lipid.diet was fed to establish the high lipid model of Coturnix coturnix. The normal control group, high lipid model group, high dose of perilla seed group（2.5 g/kg）, low dose of perilla seed group （0.83 g/kg） were designed to measure the contents of total cholesterol （TC）, three acids glyceride （TC）, high density lipoprotein cholesterol （HDL-C）, low density lipoprotein cholesterol （LDL-C）, very low density lipoprotein cholesterol （VLDL-C） and malondialdehyde （MDA）, superoxide dismutase （SOD） activity. [ Result] All the test groups could decrease TC ,TG,LDL-C and MDA content and significantly increase the HDL-C content （p 〈 0.01） and SOD activity（p 〈 0.01 ） in serum. [ Conclusion] Perilla seed has the blood lipid regulation and peroxidation function.展开更多

Quail egg white was dehydrated by air convection using one of two temperatures and times: M1 (65℃, 3.5 h), M2 (65℃, 5.0 h), M3 (70℃, 3.5 h) and M4 (70℃, 5.0 h). Lyophilized quail egg white was used as a standard. All four air-dried treatments had good protein levels (92.56% to 93.96%), with electrophoresis showing the predominant proteins to be lysozyme, ovalbumin and ovotransferin. Denaturation temperatures ranged from 81.16℃ to 83.85℃ and denaturation enthalpy values from 5.51 to 9.08 J/g. Treatments M1-4 had lower water-holding (0.90 - 2.95 g/g) and oil-holding (0.92 - 1.01 g/g) capacities than the lyophilized treatment (4.5 g/g, 1.95 g/g, respectively). Foaming capacity was pH-dependent in all five treatments, with the lowest values at alkaline pH and the highest (153% to 222%) at acid pH (pH 2). Foam stability was lowest at acid pH and highest at alkaline pH. Emulsifying activity in the air-dried treatments was highest at pH 8 (41% - 46%). Emulsion stability was pH-dependent and highest in M3 between pH 2 and 4 (96.16% to 95.74%, respectively). In the air-dried treatments, in vitro protein digestibility was as high as 83.02% (M3).展开更多

There is limited published information on the histological features of the intestinal tract of Japanese quail. The only comprehensive reference is a book published in 1969. This study aims to fill that niche by providing a reference of general histological features of the Japanese quail, covering all the main sections of the intestinal tract. Both light and scanning electron microscope(SEM) images are presented. Results showed that the Japanese quail intestinal tract is very similar to that of the chicken with the exception of the luminal koilin membrane of the gizzard. Scanning electron microscopic photomicrographs show that in the Japanese quail koilin vertical rods are tightly packed together in a uniform manner making a carpet-like appearance. This differs in chicken where the conformations of vertical rods are arranged in clusters.展开更多
