Abstract: [Objective] We research the biochemical characteristic of Hetian sheep based on their blood physiological and chemical indexes,then,explore the correlation between blood physiological and chemical indexes and body weight,body size. [Method] The body weight,body size and blood physiological and biochemical parameters of Hetian sheep in 7-month-old and 10-month-old were measured,respectively. [Results] The result showed that when Hetian sheep was in 7-month-old and 10-month-old,correlation analysis suggests that there was significant positive correlation between some indicators (P<0.05),such as heigh t/body weight,heigh t/chest girth.Influences of gender and age on some of the blood physiological and biochemical parameters were significant.Hematocrit (HCT)of rams in 7-month-old and 10-month-old were significantly higher than that of ewe (P<0.05).Alkaline phosphatase (ALP)of rams in 7-month-old and 10-month-old were higher than that of ewe,but this difference was not significant (P>0.05).When Hetian sheep was in 10-month-old,there were significantly positive correlation between some indicators (P<0.05),such as body weigh t/total cholesterol (TC),heigh t/aspartate aminotransferase (AST),heigh t/total cholesterol (TC);Whereas,there was significant negative correlation between some indicators (P<0.05),such as cannon bone circumference/triglyceride (TG),cannon? bone circumference/alkaline phosphatase (ALP). [Conclusion] There are some correlations between body weight,body size and blood physiological and biochemical parameters,the results can provide some reference for breeding,feeding and management of Hetian sheep.
