Abstract: The aim of this study was to explore the adaptability of Hu sheep in the alpine region of northwest China. Samples from 12 Hu sheep (six males and six females) in the Tianzhu area were collected at 3, 6, 12, and 24 months of age to analyze the effects of sex, age, and their interactions on several physiological and biochemical indexes. The results showed that sex had a significant or extremely significant effect on the mean corpuscular hemoglobin concentration (P<0.05) and glutamic-oxalacetic transaminase activity (P<0.01). Age significantly affected respiration, the number of white and red blood cells, platelet count, mean platelet volume, alkaline phosphatase activity, and total cholesterol (P<0.05). Age had highly significant effects on body temperature, mean corpuscular hemoglobin concentration, mean corpuscular hemoglobin concentration, and the activities of glutamic-pyruvic transaminase, glutamic-oxalacetic transaminase, and lactic dehydrogenase (P<0.01). There was a significant interaction between sex and age for mean corpuscular hemoglobin concentration and blood glucose concentration (P<0.05), and a highly significant interaction between sex and age for lactic dehydrogenase activity (P<0.01). The physiological, blood, and biochemical indexes of the test Hu sheep differed from those of Hu sheep in their original domestic region and in low-altitude regions. These findings indicate that Hu sheep are highly adaptable to alpine regions and provide a scientific basis for producing Hu sheep in the Northwest alpine region.
