| 摘 要： | 2011年3—5月及8—10月,以山东省临沂市兰山区众合牧业有限公司小尾寒羊种羊场圈养的成年母羊为研究对象,利用24h监控系统,采用目标动物取样法和全事件记录方法,研究了小尾寒羊成年母羊昼夜行为节律。结果显示,小尾寒羊昼夜反刍、卧息、取食、运动、站立与观望、修饰行为及其他行为持续时间依次减少。对小尾寒羊0：00—24：00各时段行为变量分析表明,其取食与反刍行为有2个高峰期,卧息全天都表现比较高的行为持续时间,而高峰期则发生在12：00—14：00。小尾寒羊观望行为有2个高峰期,分别在8：00—10：00及18：00—20：00。按照春秋季节规律特点,以06：00—18：00为白昼,其余时间为夜间。以Mann-Whitney U检验进一步分析圈养条件下小尾寒羊春秋季行为节律特点,结果表明,春秋季节,昼间小尾寒羊母羊在取食与其他行为上存在极显著差异,而夜间在取食、观望与其他行为上存在显著或极显著差异。在春季和秋季昼间与夜间行为对比分析表明,春季除卧息与运动行为外,另外5种行为均存在显著或极显著差异。秋季除卧息、修饰和其他行为外,其余4种行为均存在显著或极显著差异。对春秋季24h行为节律分析发现其取食行为存在极显著差异,运动行为与其他行为存在显著差异。对春秋季小尾寒羊成年母羊昼夜行为节律的研究可为认识圈养条件下小尾寒羊习性、改善小尾寒羊饲养管理与福利条件提供基础资料。

| Abstract: | The activity rhythm of mature female small-tailed Han sheep in household condition were researched in spring from March to May and autumn from August to October season in Lanshan district,Linyi city in 2011. The 24 hours monitoring system was employed to observe the sample＇s behavior. All occurrence method was used to record behavior rhythm day and night. The results showed that the duration time ruminating, relaxing, eating, moving,ob- serving, grooming and other behavior were decreased one by one. Each period behavior variable analysis during 0：00- 24：00 showed that the eating and ruminating behavior had two peak periods. Relaxing behavior rates showed high in all the behavior of the duration, and peak time occurred in 12：00-14：00. The observing behavior had two peak periods in 8：00-10：00 and 18：00-20：00, respectively. According to the spring and autumn season regulation, the 06：00-18：00 time was defined as the day and the rest as the night. The season behavior rhythm was detected with Mann-Whitney U method. The results showed that during the spring and autumn season with day time, eating and other behavior showed a high significant difference. The observing,eating and other behavior showed significant difference at night time. In the spring and autumn season, night and day time behavior contrast analysis showed that in addition to rela-xing and moving behavior in the spring, the other five types of behavior had significant difference. In addition to rela- xing,grooming and other behavior, the four types of behavior had significant difference in the autumn season. The rhythm of eating behavior showed significant difference,moving behavior and other behavioral had significant differ- ences with 24 hours observe with two seasons. To analysis the behavior rhythm in captive condition would provide the information of its habits, improve its breeding management and welfare conditions. |
