【摘要】 为了研究西北寒冷干旱气候条件下湖羊的行为和生理指标变化,进而为西北地区湖羊引种提供数据支持和理论依据,本试验选用12只（公、母各半）舍饲周岁湖羊,通过近红外摄像技术研究了不同季节（A因子,A₁夏季,A₂冬季）、性别（B因子,B₁♂,B₂♀）和不同时段（C因子,C1昼,C2夜）条件下湖羊的采食、饮水、反刍、卧息等行为。结果表明,季节因子（A因子）对湖羊采食、卧息、反刍等行为均有极显著影响（P<0.01）;性别因子（B因子）仅对湖羊采食和卧息行为有显著影响（P<0.05）;昼夜因子（C因子）对湖羊的卧息行为有显著影响（P<0.05）,对其采食和反刍行为有极显著影响（P<0.01）。季节和性别的交互作用对湖羊采食行为有显著影响（P<0.05）,对反刍行为有极显著影响（P<0.01）。其余因子间交互作用对湖羊行为学无显著影响。试验羊体温、心跳、呼吸频率和血常规等生理指标均在正常范围内。以上结果说明湖羊在当地表现出了良好的适应性,在西北地区引种湖羊可行。更多还原

【Abstract】 The objective of this study was to investigate the behavioral and physiological indices of Hu sheep in the arid and cold areas of northwest China.Twelve 1-year-old Hu sheep（6rams and 6ewes）were evenly divided into two groups.The effects of season（A factor:A₁ summer,A₂winter）,sex（B factor:B₁♂,B₂♀）and time（C factor:C₁day,C₂night）on feed intake,water intake,rumination,resting time and physiological indices were measured using near-infrared camera techniques.The results showed that seasonal factors had highly significant effects on feed intake,rumination and resting time（P<0.01）.The sex factor had significant effects on feed intake and resting time（P<0.05）,while the time factor had significant effects on resting time（P<0.05）and highly significant effects on rumination（P<0.01）.In addition,only the seasonal and sex factors interacted with feed intake（P<0.05）and rumination（P<0.01）.The physiological indices of Hu sheep,for instance body temperature,heartbeat,respiratory rate and blood routine examination,were within normal ranges during this experiment.In conclusion,there was no significant impact on the fundamental characteristics and general performance of Hu sheep and it is feasible to introduce them into the arid and cold areas of northwest China.更多还原
