Molting is a natural physiological phenomenon involving the periodic replacement of old feathers with new ones in the avian species. During mid-November an extensive loss of feathers in Japanese quail was observed in our breeding colony. The cause of molting could not be established, however, lower ambient temperatures may have played a major role and the decrease in day length could not be rul...

The quantitative matching hypothesis of neuronal cell death was tested for the chick hindlimb by determining the relationship between myotube number at the onset of motoneuron cell death and the number of motoneurons that survive in chicks, quail, and chick-quail chimeras. Hindlimb buds, which differ in size between the 2 species, were exchanged at stages 16 1/2-19, myosin ATPase-stained myotub...

AIM To investigate the status, problems and prospects of Japanese quail (Coturnix coturnix japonica) farming in selected areas of Bangladesh. MATERIALS AND METHODS The study was conducted in 14 districts of Bangladesh, viz., Dhaka, Narayanganj, Munshiganj, Mymensingh, Netrakona, Faridpur, Jessore, Khulna, Satkhira, Kushtia, Bogra, Naogaon, Comilla, and Sylhet during the period from July 2011 ...

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...

Relevance. Identification and analysis of the reasons for reducing egg productivity is an urgent problem in quail breeding. The aim this study to assess destructive processes somatic cells ovarian follicles (the level apoptosis pycnosis) mature layers different connection with production quality indicators eggs. Methods. In experiments, pyknosis granulosa 3–8 mm females Estonian, Manchurian, En...

The study aimed to determine evaluate the use of sorghum as a substitute for maize in laying quail diet and its effect on performance quality eggs produced best levels lutein (Marigold flower extract) canthaxanthin inclusion based Japanese feed well influence storage time eggs. A total 680 quails (Coturnix coturnix japonica), with 64 weeks age was distributed 4 × x4 factorial + 1 control scheme...

In India, quail was introduced two decades ago and has partially replaced the domestic fowl both in research and open market for human consumption. The quail originally domesticated around 11th century as a pet song bird, is now highly valued [1,2]. Quail reproduces throughout the year on contrary to seasonally breeding birds. It attains the maturity at 28 days and first decline of fertility ha...

The purpose of the current study was to detect effects different levels rosemary volatile oil (VO) supplemented laying quail diets on performance, egg quality parameters, and yolk oxidative stability. In this study, a total 105 quails (Coturnix coturnix Pharaoh) at age 6 weeks were used 3 main groups formed, each containing 35 quails. Also, group separated into 5 replicates an equal number Quai...

H9N2 influenza viruses have become established and maintain long-term endemicity in terrestrial poultry in Asian countries. Occasionally these viruses transmit to other mammals, including humans. Increasing epidemiological and laboratory findings suggest that quail may be an important host, as they are susceptible to different subtypes of influenza viruses. To better understand the role of quai...
