摘要
作者在前人研究的基础上 ,利用最小二乘分析原理 ,制定了目标性状日增重(ADG)、背膘厚 (BF)、饲料效率 (FCR)三性状的综合评定指数I =10 0 +0 .0 4× (ADG -ADG) - 4 .88× (BF -BF) - 2 5.94× (FCR -FCR) ,可作为种猪中心测定评定种猪时参考 .
On the basics of predecessors, a comprehensive select index ( I ) of the goal traits was formulated by least square analysis, in which average daily gain(ADG), Backfat thickness(BF) and feed consumption rate(FCR) were involved. It was I =100+0.04×(ADG- ADG )-4.88×(BF- BF )-25.94×(FCR- FCR ). It can be a reference for performance testing in central station.
