摘要
为研究澳大利亚进口的杜泊羊和萨福克羊2个品种在宁夏银川的行为特征,在舍饲饲养条件下对其行为进行昼夜跟踪观测。选取3月龄、1岁、3岁的杜泊羊和黑头萨福克羊为试验对象,每阶段每个品种各4只,其中公、母羊各2只,对羊的采食、站立、反刍、卧息、游走、饮水、排泄及其他行为的时间进行观察记录。结果表明:杜泊羊站立的时间极显著高于萨福克羊(P<0.01),其采食和其他行为时间极显著低于萨福克羊;母羊的采食和其他行为时间显著高于公羊(P<0.05),而站立和排泄的时间极显著低于公羊(P<0.01);3月龄羊的采食时间极显著高于3岁和1岁羊(P<0.01),1岁羊极显著高于3岁羊。3岁羊的站立时间极显著高于3月龄和1岁羊(P<0.01)。1岁羊的反刍时间极显著高于3月龄和3岁羊(P<0.01),3岁羊的反刍时间显著高于3月龄羊(P<0.05)。3月龄羊的卧息时间极显著高于1岁羊(P<0.01);1岁羊的游走时间显著高于3岁羊(P<0.05)。1岁羊的饮水时间显著高于3月龄羊(P<0.05)。杜泊羊随年龄增长,其采食、卧息时间逐渐减少,站立时间逐渐增加,萨福克羊随年龄增长,其采食量逐渐减少。由此可知,杜泊羊和黑头萨福克羊的行为受年龄、性别、品种因素影响,其中年龄对羊的行为影响最大。
In order to study the behavioral characteristics of Dorper sheep and Suffolk sheep imported from Australia in Yinchuan,Ningxia,their behaviors were observed day and night under the condition of barn feeding.3-month-old,1-year-old and 3-year-old Dorper sheep and black-headed Suffolk sheep were selected,and there were 4 sheep of each variety in each stage,including 2 rams and 2 ewes.Their grazing,standing,ruminating,lying,walking,drinking,excretion and other behaviors were observed and recorded.The results show that the standing time of Dorper sheep was highly significantly longer than that of Suffolk(P<0.01),yet the grazing time and other behaviors were highly significantly shorter than those of Suffolk sheep.The grazing time and other behaviors of ewes were significantly longer than those of rams(P<0.05),while their standing time and excretion time were highly significantly shorter than rams’(P<0.01).The grazing time of 3-month-old sheep was highly significantly longer than that of 3-year-old and 1-year-old sheep(P<0.01),and that of 1-year-old sheep was highly significantly longer than that of 3-year-old sheep.The standing time of 3-year-old sheep was highly significantly longer than that of 3-month-old sheep and 1-year-old sheep(P<0.01).The ruminating time of 1-year-old sheep was highly significantly longer than that of 3-month-old and 3-year-old sheep(P<0.01),that of 3-year-old was significantly longer than 3-month-old(P<0.05).The lying time of 3-month-old sheep was highly significantly longer than that of 1-year-old sheep(P<0.01),the walking time of 1-year-old sheep was significantly longer than that of 3-year-old sheep,and the drinking time of 1-year-old sheep was significantly longer than that of 3-month-old sheep(P<0.05).While growing up,for Dorper sheep,the time of grazing and lying decreased,yet the time of standing increased gradually;for Suffolk sheep,the feed intake decreased gradually.To sum up,the behaviors of Dorper sheep and black-headed Suffolk sheep are affected by age,gender and variety,among
