[Objectives] This study was conducted to investigate the characteristics of physiological,hematological and blood biochemical parameters in introduced Hu sheep reared in the Zizhong area of Sichuan Province in spring.[Methods] Ten healthy adult rams and ten healthy adult ewes aged 3-5 years were selected, and relevant parameters were measured.[Results] No significant differences were observed between rams and ewes in body temperature, respiratory rate, and heart rate(P> 0.05). Among hematological parameters, except for a significantly higher total platelet count in ewes (P< 0.05) and a significantly higher lymphocyte percentage in rams (P< 0.05), no significant differences were found between rams and ewes in other 11 indicators, including total red blood cell count, total white blood cell count, and hemoglobin concentration (P> 0.05).Among blood biochemical parameters, blood urea nitrogen (BUN), alanine aminotransferase (ALT), and the urea nitrogen-to-creatinine ratio were significantly higher in rams than in ewes (P < 0.05). No significant differences (P > 0.05) were observed between rams and ewes in 13 indicators, including total protein, albumin, glucose, and creatine kinase (CK).Overall, the physiological, hematological, and blood biochemical parameters of Hu sheep under housed conditions in the Zizhong area remained stable, with only a few indicators showing significant differences between sexes. This pattern reflects subtle physiological regulatory differences in metabolism and immune function between rams and ewes.[Conclusions] This study provides fundamental data for understanding the physiological adaptability of Hu sheep in the region. |
