摘要
To investigate the seasonal changes in physiological and biochemical indexes of Tibetan sheep in Hongyuan area,we measured the physiological and biochemical indexes of Tibetan sheep at four different seasons. The results showed that the body temperature,respiration and heart rate of Tibetan sheep at four seasons were 39. 18- 39. 60 ℃,27. 20- 49. 04 times / min,91. 87- 106. 25 times / min,respectively. The indexes of WBC,MCV,MCH and MCHC in autumn and winter were significantly higher than those in spring and summer（ P 〈 0. 01）,while the indexes of RBC,HCT and RDW-CV in spring and summer were significantly higher than those in autumn and winter（ P 〈 0. 01）. The PLT did not vary greatly in spring,summer or autumn,but were all extremely higher than that in winter（ P〈 0. 01）. The HGB maintained stable in the four seasons. The indexes of TP,ALB and GLO in summer and autumn were extremely higher than those in winter and spring（ P 〈 0. 01）,while the indexes of ALP and PCHE in summer and autumn were extremely lower than those in winter and spring（ P 〈 0. 01）. The indexes of AST,ALT,LDH,GLU,CHOL and CA maintained stable in all seasons.
