Optimizing Early Selection Indexs on Lamb of Suffolk × Small Tail Han Sheep
摘要
Abstract
In order to optimize early selection indexs of the F1(s×H) lamb,The effects of 90 days' body weight and size index on 180 days body weight of Fl(s×H) lamb was studied by methods of correlation analysis,path analysis and determination coefficient analysis.The results showed that the index of body weight and body form of F1(S×H) lamb on 90 days had a significant influence on body weight of 180 days.Further analysis showed body weight,cannon circumference and body hight of 90 days should be focused on in early selecting of F1(s×H) lamb.The multi-regression equation was established:Y =-26.858 + 0.567X1 + 0.540X4 +3.221X2.This can provide a reference for the production and operation of lamb.关键词
