In situ implantation of a quail wing bud into a chick embryo at 4 days of incubation (E4) regularly results in the normal development of the implant followed by its acute rejection starting within two weeks post-hatching. If the epithelial thymic rudiments of the quail donor are implanted into the branchial arch area of the chick recipient after partial removal of its own thymic primordia, a ch...

A study was conducted with four types of quail named Japanese (J), White (W), Black (BL) and Brown (Br) quail in BLRI, Savar, Dhaka to understand their productive and reproductive performances. A total of 1953 day-old chicks of quails were produced in successive two hatches. The highest fertility and hatchability were observed in White (98.13%) and Japanese (73.20%) types compared to their coun...

Recent advances in cell biology open the way for studying aspects of blood-brain bamer (BBB) formation and function that have puzzled investigators since Ehrlich and Goldmann first described the barrier. Although the endothelial cells in the microvessels of all tissues appear to arise from common mesodermal precursors, considerable organ-to-organ variability exists in their ultrastructure and p...

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...

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...

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...

Present study investigates the role of temporal phase relation of serotonergic and dopaminergic oscillations in the regulation of seasonal reproduction in summer breeding Jungle bush quail, Perdicula asiatica and autumn breeding rain quail, Coturnix coturnix coromandelica. Two sets of experiments were performed in month of August, in reproductively quiescent (RQ) bush quail and reproductively a...
