Abstract
Cross fertility between wild Japanese quail and domestic quail was explored in an experiment conducted on 18(3♂, 15♀)wild Japanese quails in Weishan Lake area, 18(3♂, 15♀)medium-sized domestic quails and 18(3♂, 15♀)pint-sized domestic quails, which were divided into nine groups. This study demonstrated that wild quail could succeed in crossing with domestic quail,producing fertilized eggs and hatching first filial generation. The findings indicated that there were no reproduction isolation between the wild Japanese quail and domestic quail, and that the best cross combination was between wild male quail and medium-sized domestic female quail, in which the fertility rate and hatchability of fertilized eggs amounted to 42.86% and 29.63% respectively. Based on the results, a new way could be adopted to protect, exploit and utilize genetic resources of wild quail. (Asian-Aust. J. Anim. Sci. 2003. Vol 16, No. 10 : 1421-1423)
Highlights
Quail (Coturnix japonica) is a species belonging to Coturnix, Phasianidae, Callifermes, Aves (Chang, 1995)
Resent studies prove that wild Japanese quail in Weishan Lake area and domestic quail share the same origin in fairly recent times, compared with wild Japanese quail and domestic quail (Chang et al, 2001)
The three types of female quail made no obvious difference in hatchability of fertilized and hatching eggs (Table 2)
Summary
Quail (Coturnix japonica) is a species belonging to Coturnix, Phasianidae, Callifermes, Aves (Chang, 1995). With the development of people’s living standard, adaptation of food component and the exploitation of health protection food, the nutrition and taste of quail products have become more and more popular (Zhao, 1993; Chang, 1998). In addition to their specialty of easy feeding, convenient management, simple instruments, less investment, high benefit and high medical value, the quail has produced a flourishing industry in recent twenty years (Bai, 1993; Liu, 1998).
