this study aimed to evaluate the antioxidant property of chavir plant on japanese quail intoxicated with carbon tetrachloride (ccl4). eighty, one-d-old japanese quail chicks were randomly allotted to 4 treatments with 4 replicates and 5 chicks in each, using completely randomized design with 2×2 factorial arrangements including 2 levels of chavir powder (0 and 1.5 percent) and ccl4 (0 and 1 ml/...

this study has been carried out to investigate the effect of short-term divergent selection for 4-wk body weight on growth curve parameters and carcass components in japanese quail. quail lines utilized were two divergently selected for high (hw) and low (lw) 4-wk body weight (bw) as well as a line as control (c). the results of the study indicated that quails in hw line had heavier bw than tho...

$ EVERAL releases of Japanese Quail (Coturnix coturnix japonica) have been l__. made in the United States since 1956. This attempted stocking appears to have been unsuccessful, as were releases of this form and C. c. coturnix made more than fifty years ago (Phillips, 1928). However, recent interest in the bird has pointed up its qualities as an experimental animal. As Padgett and Ivey (1959) po...

The technology drive from egg production in relationship with genetic selection makes today’s egg production quails quite different from those of a decade ago. For instance age at 5 percent production is now earlier and total egg number has increased. The quail eggs are renowned for their high biological value (George, 2002). Although it was first considered mainly as a model animal for commerc...

AIM The growth promoting effect of the blue-green filamentous alga Spirulina platensis (SP) was observed on meat type Japanese quail with antibiotic growth promoter alternative and immune enhancing power. MATERIALS AND METHODS This study was conducted on 180 Japanese quail chicks for 4 weeks to find out the effect of diet type (vegetarian protein diet [VPD] and fish meal protein diet [FMPD])-...

Male Japanese quail (Coturnix japonica) that conspecific females preferred in a 10-min, forced-choice test of affiliative preference were more likely than were males not preferred in such a test to fertilize females' eggs when subsequently mated with them, although preferred and nonpreferred males mated equally often with females. Further, the probability that a nonpreferred male would fertiliz...

Research performed on transgenic animals has led to numerous advances in biological research. However, using traditional retroviral methods to generate transgenic avian research models has proved problematic. As a result, experiments aimed at genetic manipulations on birds have remained difficult for this popular research tool. Recently, lentiviral methods have allowed the production of transge...

European quail (Coturnix c. coturnix) may share with Japanese quail (Coturnix c. japonica) its potential as an intermediate host and reservoir of avian influenza viruses (AIV). To elucidate this question, European quail were experimentally challenged with two highly pathogenic AIV (HPAIV) (H7N1/HP and H5N1/HP) and one low pathogenic AIV (LPAIV) (H7N2/LP). Contact animals were also used to asses...

Brachiocephalic arteries in quails are large arteries which are arising separately from the aortic arch. The aim of the present study was to determine the histomorphometric aspects of brachiocephalic arteries in the Japanese quail. The different layers of the brachiocephalic artery were studied quantitatively in 10, 20 and 60 days-old Japanese quail; (n = 6) and both sexes. Luminal diameter, th...

Based on detection of hepatic residues, scavenging and predatory non-target raptors are widely exposed to second generation anticoagulant rodenticides (SGARs). A small proportion, generally <10%, of tested birds are diagnosed as acutely poisoned. Little is known, however, of sub-lethal effects of SGARs, such as interaction of clotting capacity with traumatic injury. Assessment of coagulation fu...
