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 effect of environmental conditions on hatching indices of poultry eggs is sufficiently important that new methods for their improvement are sought, among others through exposing the eggs during hatching to an artificially generated magnetic field of variable frequency. Hatching eggs in this study came from Pharaoh quail in the 4th month of laying. The flock was kept under optimum microclima...

Young birds, in their post-natal growth period, may reduce their growth and metabolism when facing a food shortage. To examine how such responses can be mediated by endocrine-related factors, we exposed Japanese quail chicks to food restriction for either 2 days (age 6-8 days) or 5 days (age 6-11 days). We then measured growth and resting metabolic rate (RMR), and circulating 3,3',5-triiodo-l-t...

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...

This study was conducted to verify whether vitamin (Vit) E or natural clay as feed additives has the potential to modulate the deleterious effects resulting from exposure to cadmium (Cd) in growing Japanese quail. 648 Japanese quail chicks (1 week old) were used to evaluate the effects of dietary Cd (0, 40, 80 and 120 mg/kg diet) and two levels of Vit E (0, 250 mg/kg diet) or two levels of natu...

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...

Diallel crosses were used to investigate the genetic inheritance of stress responsiveness through examination of population effects in progeny of randombred (RB) quail and quail selected for reduced (low stress, LS) or exaggerated (high stress, HS) plasma corticosterone (CS) response to brief immobilization. The three genotypes were crossed in a 3 x 3 factorial arrangement of treatments that al...

Loószová A., V. Revajová, M. Levkut, J . Pist l: Pathogenesis of Eimeria colchici in the Intestine of Chickens and the Related Immune Response. Acta Vet. Brno 2001, 70: 191-196. To study the immune response in poultry, a non-specific host for pheasant Eimeria colchici coccidium, ten-day-old chickens were each orally inoculated with 106 oocysts. For determination and comparison of coccidia invas...
