The Study On The Relationship Between Blood Physiological And Biochemical Indexes And Body Weight In Xinjiang Bashbay Sheep

In this experiment, the relationship was studied between the body weight and blood physiological and biochemical indexes that contains the polymorphisms and the relative concentration of blood lactate dehydrogenase (LDH),esterase(Es),α-amylase(α-Amy) and the concentration of blood Ca, P, GOT, GPT, glucose(Glu)in ten Xinjiang Bashbay lambs(when they were 5,10,15,20,30 days old) and ten one year old Xinjiang Bashbay sheep. These animals were random sampled from the herding sheep in natural state. These indexes were analyzed by electrophoresis and colorimetric analysis method respectively. The relationship was analyzed by the principles and methods in biological statistics through the SPSS software. The results showed that there were different isoenzyme phenotypes in different growth stages, that there were 5 LDH phenotypes,7 Es phenotypes,3 α-Amy phenotypes. There were significant (P<0.05) differences in different growth stages. There were positive significant (P<0.01) correlation between the body weight and the relative concentration of LDH3, GOT, GPT, Es5 (5,15,20 days and 1 year old) 。 There were negative significant (P<0.01) correlation between the body weight and the concentration of Glu , Es1(5 days) , Es2(15,20 days). The nine optimum regression models that concluded from the stepwise regression were constructed by these parameters, they could be used in estimating the body weight in different growth stages. It was suggested from the study that select the four characters of blood LDH3 , GOT , GPT , Es5 at early period could be used as the genetic markers , an assistant method and reference basis for Xinjiang Bashbay Sheep breeding .
