    摘要:

    比较不同类型终端父本生产性能的差异,为终端父本选择提供依据。对温氏集团自主选育的杜洛克及二元杂交公猪的日增重、料重比、背膘厚、体长、体高等性状进行测定并比较,得出不同类型终端父本的性能差异。结果表明杂交终端父本在生长性能、体型、精液品质等方面均优于纯种公猪。皮杜S122适合作为终端父本用于肉猪配套系生产。

    Abstract:

    In order to provide references for the selection of terminal sire to produce commercial pigs, performance of different kinds of terminal sires were compared. The traits of Duroc boar and hybrid-boar bred by Wens were determined, including average daily gain, feed/gain ratio, back fat thickness, body length and body height. The performances of different types of terminal sires were compared. The results showed that the hybrid terminal sire was superior to purebred boars in terms of growth performance, body size and semen quality. S122, crossed by S22 Duroc and Pietrain, is an excellent terminal sire for commercial pig production.
