瘦肉型生长肥育猪某些血液化学性状与增重的关系

测定了60-75日龄杜洛克×施格杂交1代仔猪9项血液化学性状,估测了血液性状间及其性状与日增重的表型相关。并在此基础上进行通径分析。结果表明:血清Se,Cu,AKP含量与日增重呈显著相关(相关系数分别为0.4757~(**),0.4125~(**),-0.3698~*);AKP,Se,Cu,GSH-PX的含量与日增重通径系数分别为-0.8416,0.5006,0.4904,0.4099,均达显著水平。因而,AKP,Se,Cu,GSH-PX可作为影响瘦肉型生长肥育猪的相对重要性状。

Relationships Between Some Blood Chemical Characters and Daily Gains in Growing Pigs

The relationships among nine kinds of blood chemical characters, and between each of the charactcrs and daily gains were estimated with phenotypic correlation analysis in 60—75 days pigs (Doroe×Segher). After that the path analysis was carried out. The results were as follows: (1) the correlations between Se, Cu, AKP in serum and daily gains are greatly significant. The. correlation coefficients are 0.4757, 0.4125, -0.3698, respectively. (2) The relationship between AKP, Se, Cu, GSH-PX in serum/blood and daily gains are significant with path analysis. The path coefficients are -0.8416, 0.5006, 0.4904, 0.4099 respectively. The results indicated that AKP, Se, Cu and GSH-PX can be used as relative important properties, which may effect the growth of growing pigs.
