| 摘 要： | <正> 一、研究目的 二花脸猪是太湖猪的一个类群,以繁殖性能高、肉质鲜美而著称于世,但育肥性能和胴体品质较差。猪的经济性状视其遗传力的高低有不同的改良途径。本文旨在研究以二花脸猪作母本的杂交组合试验,分析杂种优势在繁殖性能、育肥、胴体等性状上的表现,筛选最佳组合,为二花脸猪的利用提供科学的依据。

THE EFFECT CROSSBREEDING OF THE ER-HUA-LIAN ( MEI-SHAN ) PIGS WITH DUROC JERSEY AND LARGE WHITE |
| |
| Abstract: | The corsses of local Er-Hua-Lian ( Mei-Shan ) breed with Duroc Jersey or Large white showed very high heterosis in reproductive performance,being higher in 3-way crosses than in 2-way crosses, Lsing Duroc Jersey as the terminal sires was better than using Large white in economic bcnifits. In the crosses of D× ( LW×EH ) , the number of pigs farrowed alive, daily weight gain during growing-finishing period, feed conversion rate, lean% averged 15.05, 748 grn, 3.56, 57.75%, respectively. The author was of the opinion that D×( LWXEH ) combination is better suited for production of lean-type commercial pigs in this area. |
