以豁眼鵝為父本的肉鵝雜交模式研究
[Abstract]:In order to evaluate the effect of hybrid utilization of Huoyan geese as male parent, Huoyan goose was used as male parent and Sichuan white goose as female parent. The body size and slaughtering performance were measured at the age of 10 weeks, and the body size and slaughter performance were measured at the age of 10 weeks. The results showed that the weight index of crossbred geese was better than that of other pure lines, but there was no significant difference (P0.05). In the aspect of slaughtering performance, the total weight of sternum and pectoral muscle rate of crossbred geese were better than that of pure line goose, and the difference was significant (P0.05) or extremely significant (P0.01), and the pectoral muscle rate of crossbred geese was better than that of pure male goose in the three groups of geese (P0.05) or extremely significant (P0.01). But there was no significant difference with Sichuan White Goose (P0.05). In terms of body size, there were differences in body size of Huoyan goose, Sichuan white goose and hybrid goose. Among them, the body oblique length, shank circumference and diving length of crossing goose in three groups were higher than those of pure line (P0.05). The body oblique length, keel length and chest depth of crossbred geese were significantly higher than that of pure male geese (P0.05), and the diving length of crossbred geese was higher than that of pure male geese (P0.01). Therefore, Huoyan goose can be used as a male parent for cross utilization.
