摘要
对全放牧在干旱半荒漠条件下的中卫山羊春季主要行为进行昼夜连续24小时跟踪观测研究表明,春季中卫山羊日采食分为两个游走状态采食时段和1个补饲采食日段,全天采食时间510.0±30.3分;反刍主要发生在夜间,并有两个高峰期,即23:00左右和3:00~6:00之间反刍强度最大,全天反刍时间420.2±30.3分,反刍与采食时间之比为0.8:1;睡眠有深睡眠和浅睡眠之分,总时间135.3±45.4分;春季每天饮水一次,水味咸,总时间5.5±1.6分;春季每天牧程近30km;成年母羊平均体重24.6kg(n=168);3月龄羔羊哺乳行为由3个行为组分构成,吮乳的主行为时间不超过5秒钟,中卫山羊适应性强,合群性好,对大群放牧极有利。
The spring principal behaviors of Zhongwei goat have been ob-served by day and night tracking.There were two grazing stages and one supplement stage during day and night. The total grazing time was 510.0±30·3 minutes every day. There were two chief ruminant periods which were about 23:00 o'clock and between 3:00 and 6:00 o'clock. Ruminant time was 420.2±30.3minutes. The ratio of the time of rumination and graze was 0.8:1.Total sleeping time was 135.3±45.4 minutes. There was one period of dri-nking water every day. Total time of drinking water was 5.5±1.6 minutes.Total grazing distance every day was 30 km.Average weight of doe was 24·6kg.There were three behavior components on the nursing behavior of 3-months-kid. Nursing time every time is no less than 5 seconds. It is con-sidered that Zhongwei goat has good flocking behavior,which is useful for flock grazing
