摘要: 为研究湖羊在西北高寒地区的适应性,本试验选择引入天祝县的舍饲3,6,12,24月龄湖羊各12只(公、母各半),测定其夏季生理、生化指标,分析性别、月龄因子及两者交互作用对天祝地区湖羊生理、生化指标的影响。结果表明,性别因子对平均红细胞血红蛋白浓度影响显著(P<0.05),对谷草转氨酶影响极显著(P<0.01);月龄因子对呼吸、白细胞数、红细胞数、血小板数目、平均血小板体积、碱性磷酸酶和总胆固醇的影响显著(P<0.05),对体温、平均红细胞血红蛋白含量、平均红细胞血红蛋白浓度、谷丙转氨酶、谷草转氨酶和乳酸脱氢酶的影响极显著(P<0.01);性别和月龄的交互作用对平均红细胞血红蛋白浓度和葡萄糖有显著影响(P<0.05),对乳酸脱氢酶有极显著的影响(P<0.01)。各月龄试验羊只的生理和血液生理、生化指标虽与原产地及低海拔引种地区有差异,但均在正常范围内,在当地表现出良好的适应性,为湖羊在西北高寒地区的引种及推广提供了科学依据。

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.
