摘要: 为了解皖西白鹅与霍尔多巴吉鹅杂交后代的外貌特征和生产性能,选用皖西白鹅公鹅与霍尔多巴吉鹅母鹅进行杂交试验。结果表明,杂交鹅体型多数与霍尔多巴吉鹅一致,少数与皖西白鹅一致;成年母鹅背部有少量灰毛,其余为白色,公鹅的羽毛全部为白色。25%的公鹅头部明显有肉瘤,但比皖西白鹅的肉瘤小,另有25%的公鹅头部有肉瘤但较小,其余公鹅头部无肉瘤;母鹅头部均无肉瘤。杂交鹅1-70日龄平均增重4 795.91 g,与皖西白鹅和霍尔多巴吉鹅相比分别提高了12.70%和8.68%,差异显著(P〈0.05﹚;杂交鹅的平均产蛋量(40.4枚/只)、种蛋的受精率(90.0%)和受精蛋的孵化率(91.0%)都高于皖西白鹅,且差异显著(P〈0.05﹚,但与霍尔多巴吉鹅相比产蛋量有所下降,种蛋的受精率和受精蛋的孵化率相近。
