【摘要】：为评估豁眼鹅作为父本的杂交利用效果,本实验以豁眼鹅为父本,四川白鹅为母本,测定二者和杂交后代在1~10周龄体重,并在10周龄测定体尺及屠宰性能。结果表明:杂交鹅在体重指标上优于其他纯系,但并未表现出显著差异(P0.05);在屠宰性能方面,3组母鹅中,杂交鹅的全净膛重和胸肌率优于纯系母鹅,且与豁眼鹅差异显著(P0.05)或极显著(P0.01),3组公鹅中,杂交鹅的胸肌率优于纯系公鹅,但与四川白鹅差异不显著(P0.05)。在体尺指标方面,豁眼鹅、四川白鹅和杂交鹅存在不同程度的差异,其中3组母鹅中,杂交鹅的体斜长、胫长、胫围、潜水长等指标均高于纯系(P0.05);3组公鹅中,杂交鹅的体斜长、龙骨长和胸深高于纯系公鹅,差异显著(P0.05),杂交鹅的潜水长高于纯系公鹅,差异极显著(P0.01)。可见,豁眼鹅可作为杂交利用的父本。
[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.
