摘　　要：为了研究哺乳初期羔羊行为变化规律,在夏、冬季节共选择4批(每个季节各2批),体重(3.50±0.23)kg,随母哺乳的1日龄小尾寒羊共32只。每批羔羊选择4个羊栏,每栏饲养1只泌乳母羊及其生产的2只羔羊。采用视频监控方法对两季节哺乳初期(1~5 d)的羔羊行为进行记录,分析羔羊哺乳、探究饲料、躺卧及站立的频率及其分配时间,并分析羔羊躺卧选择的位置。结果:随着日龄增加,夏、冬两季羔羊的哺乳频率及其分配时间均表现出显著性变化,第5天显著低于第1天(P<0.05);而第5天探究饲料的分配时间高于第1天,并且冬季日均哺乳频率及分配时间均显著高于夏季(P<0.05);随羔羊的日龄增加,冬季的躺卧时间表现出减少趋势,且冬季每天的躺卧频率和躺卧时间均显著少于夏季(P<0.05);从羔羊的躺卧位置分析,夏、冬两季羔羊均偏好躺卧于边缘位置,平均比例分别为79.02%和43.75%,且夏季显著高于冬季(P<0.05),而冬季选择居中和保温箱躺卧的平均比例显著高于夏季(P<0.05)。综上,通过研究羔羊哺乳初期的行为变化规律,可为羔羊的饲养管理提供参考。The aim of this study was to investigate lambs'behavior changes during the early-suckling stages.A total of 32 small-tailed Han lambs(1 day of age,(3.50±0.23)kg of initial weight)were used in both summer and winter in this experiment,with a total of 4 batches(2 batches in each season).The lambs were raised with their mother in one pen.Each batch of lambs was distributed into 4 pens,with 2 lambs and one lactating ewe for each pen.The lambs'behaviors in both summer and winter in the period from d 1 to d 5d of age after birth was recorded using video technology,and the frequencies and the timing of suckling,feed exploring,lying,and standing of lambs were analyzed.Meanwhile,the lying position of the lambs in the pen was also investigated.The results showed that,with the increasing of ages,the frequency and duration of suckling of the lambs in both summer and winter demonstrated a significant change,with the above two parameters were lower at day 5 than that at day 1(P<0.05).The daily average time of feed exploring increased by 37.71%in summer and 50.00%in winter.Moreover,the daily average suckling frequency and duration were greater in winter(P<0.05)than those in summer.as the lamb ages increased,their lying duration in winter showed a decrease,by 1.00 h at day 5,compared with that at day 1.Also,the daily lying frequency and duration in winter was lower by 2.39 h(P<0.05)than that in summer.The lambs'lying positions in both summer and winter indicated that they would prefer to lie in the edge zone,with an average proportion of 79.02%in summer and 43.75%in winter;and the proportion in summer was greater ( P<0. 05) than that in winter. However,in winter,the average in-the-center-of-pen lying proportion was greater( P<0. 05) than that in summer. The results of this study suggested that the lambs' behavior changes in the early-suckling stage would providea reference for breeding management.
