摘要
为了了解浙东白鹅与霍尔多巴吉鹅的杂交效果,试验选用20只38周龄浙东白鹅公鹅作为父本,80只41周龄霍尔多巴吉母鹅作为母本进行杂交试验,选择100只健康初生雏鹅进行饲养观察,并与纯繁的霍尔多巴吉雏鹅和浙东白雏鹅进行同期饲养对比,分析杂交后代的羽毛(绒毛)颜色、额瘤等外貌特征,以及生长速度和屠宰性能等。结果表明:10周龄时杂交仔鹅母鹅羽毛颜色以白色为基础色,面部和眼睛后部为灰色,背部有或多或少的灰色羽毛,公鹅羽毛为纯白色。7周龄和10周龄末时,霍尔多巴吉纯繁仔鹅与杂交仔鹅的平均体重基本接近,差异不显著(P>0.05),且均显著高于浙东白纯繁仔鹅(P<0.05);10周龄末杂交仔鹅公鹅平均体重达到5.65 kg,而母鹅则为3.77 kg。10周龄时雄性浙东白纯繁仔鹅的宰前活重、胸肌率均显著低于雄性霍尔多巴吉纯繁仔鹅和杂交仔鹅(P<0.05),且后两者之间差异不显著(P>0.05);雄性杂交仔鹅的腿肌率显著高于雄性浙东白纯繁仔鹅(P<0.05),而与雄性霍尔多巴吉纯繁仔鹅相比差异不显著(P>0.05);3种鹅的屠宰率和半净膛率之间差异不显著(P>0.05)。说明浙东白鹅与霍尔多巴吉鹅的杂交后代具有良好的生产性能。
In order to understand the hybridization effect between Zhedong white goose and Hortobagy goose, 20 male Zhedong white geese aged 38 weeks and 80 female Hortobagy geese aged 41 weeks were selected as male parents and female parents for the hybridization experiment, respectively. 100 hybrid goslings were selected for feeding observation, and comparison with pure breeding of Zhedong white goose gosling and Hortobagy goose gosling in the same period, and the appearance characteristics such as feather(down feather) color, forehead tumor, growth rate and slaughter performance of hybrid offspring were analyzed. The results showed that the feather color of female geese was white, the face and the back of eyes were gray, the back had more or less gray feathers, and the male goose feathers were pure white at the age of 10 weeks. At the end of 7 weeks and 10 weeks old, the average body weight of Hortobagy geese and hybrid geese was basically similar, with no significant difference(P>0.05), and both were significantly higher than that of Zhedong white goose(P<0.05). At the end of 10 weeks old, the average weight of male and female geese reached 5.65 kg and 3.77 kg, respectively. The pre slaughter live weight and breast muscle rate of 10 week old male Zhedong white goose were significantly lower than that of male Hortobagy geese and hybrid geese(P<0.05), and there was no significant difference between the latter two(P>0.05). The leg muscle rate of male hybrid geese was significantly higher than that of male Zhedong white goose(P<0.05), but there was no significant difference compared with that of male Hortobagy goose(P>0.05). There was no significant difference between the slaughter rate and half eviscerated rate(P>0.05) in three gooses. The results showed that the hybrid offspring of Zhedong white goose and Hortobagy goose had good production performance.
