The results showed that the respiratory change range of white-Tibetan sheep in four seasons was from （32.74±21.33） to （49.96±17.62） times/min, and the variation ranges of body temperature and heart rate were from （39.27±1.05） to （39.73±0.31） ℃ and from （88.75±8.32） to （104.63±10.39） times/min, respectively. The indexes of WBC, MCV, MCH and MCHC in autumn and winter were extremely significantly lower than those in spring and summer, while RBC,HCT and RDW-CV in autumn and winter were extremely significantly higher than those in spring and summer, HGB and PLT changed in different seasons with no signifi- cance. The indexes of AST,TP, ALB, GLO and LDH in summer and autumn were relatively higher than those in winter and spring, while the indexes of PCHE, GLU, CHOL and CA in summer and autumn were relatively lower than those in winter and spring, however, the indexes of ALT and ALP were relatively higher in spring and autumn.展开更多

The results showed that the optimum separation parameters were a centrifugal speed at 6 000 r/min, centrifugal time of 20 min, a mass fraction of dry matter of 20%, an inlet air temperature at 180 ℃ and a feed rate at 400 ml/h, under which the plasma protein was a pale yellow powdery solid, indicating a good separation effect.展开更多
