I . Adult male Japanese quail (Coturnix coturnixjuponicu) were starved for 48 or 60 h and then refed for either 24 or 48 h. Weight and lipid content of carcass and livers were determined, as was the lipid content of plasma. In addition, the activities of acetyl-CoA carboxylase (EC 6 . 4 . I . 2 ; CBX), fatty acid synthetase (FAS), ATP citrate lyase (EC 4 . I . 3 .8 ; CCE) and malate dehydrogena...

The distribution of the extracellular matrix (ECM) glycoprotein, tenascin, has been compared with that of fibronectin in neural crest migration pathways of Xenopus laevis, quail and rat embryos. In all species studied, the distribution of tenascin, examined by immunohistochemistry, was more closely correlated with pathways of migration than that of fibronectin, which is known to be important fo...

Previous experimental evidence suggested that the avian segmental pattern is already specified in the apparently unsegmented paraxial (segmental plate) mesoderm, but is susceptible to modification and reconstitution. We explored capacities of embryos to alter the specified pattern and restore it after disruption. In control experiments, right segmental plates of chicken or Japanese quail embryo...

Keeping Japanese quail is an economic way for producing egg, because of their early sexual maturity (laying egg after 35 days), high egg production (250–270 eggs per year), resistance to most of poultry disease and great egg production persistency on a high level (approximately 14–18 months) (MURAKAMI and ARIKI, 1998). Japanese quail maturation happens in about 6 weeks of age and mature females...

A study was conducted to determine the effects of EM supplied in drinking water and feed on growth, egg production and waste characteristics of Japanese quail. The effect of EM on the growth of 1,000 day-old quail was assessed using a completely randomized design with four treatments: a control; EM added in drinking water at 1:5,000; EM (in the form of fermented compost or bokashi) added in fee...

Quail has been proposed to be an intermediate host of influenza A viruses. However, information on the susceptibility and pathogenicity of pandemic H1N1 2009 (pH1N1) and swine influenza viruses in quails is limited. In this study, the pathogenicity, virus shedding, and transmission characteristics of pH1N1, swine H1N1 (swH1N1), and avian H3N2 (dkH3N2) influenza viruses in quails was examined. T...

Pet bird rearing has become increasingly popular recently, and owners often raise them near to their homes. However, zoonotic infections can spread from pet birds. Thus, this cross-sectional study explored the prevalence of potentially bacterial pathogens in household birds, risk factors for transmission, antibiotic susceptibility isolated bacteria. A total 240 samples were analyzed, including ...

Gamma Coronaviruses (GCoVs) are distributed worldwide, affecting a wide range of bird species, the beluga whale, and bottlenose dolphins. Because of the limited proofreading capability in the viral encoded polymerase, they emerge genetically diverse. There has been no molecular surveillance data to describe the epidemiology of GCOVs in avian species. The present study was conducted to detect GC...

ABsT•CT.--Variation in the water, lipid, and nonlipid dry matter of eggs and newly hatched chicks of the Laughing Gull and Japanese Quail was related to variation in the size of the egg. Egg contents of the two species were, on average, very similar. Yolk size varied in direct proportion to egg size, but in the quail large eggs contained disproportionately low levels of lipid and high levels of...

The sexually dimorphic testosterone-sensitive medial preoptic nucleus (POM) of quail can be identified by the presence of a dense network of vasotocinergic fibers. This innervation is sexually differentiated (present in males only) and testosterone sensitive. The origin of these fibers has never been formally identified although their steroid sensitivity suggests that they originate in parvocel...
