摘要： 在南方人工草地上,对云岭黑山羊在不同放牧压和放牧时期的牧食行为进行研究。结果表明:放牧压指数较小时,能减少采食时间和采食时行进步数,明显增加每步吃草口数、采食速度、口食量、日采食量、反刍时间,对其他牧食行为影响不大;9月份采食口数、行进步数最少,口食量、日采食量最大,6月份每步吃草口数明显小于其他月份。7,8,9月份采食速度相差不大,小于10月份采食速度;10月份反刍时间、每个食团咀嚼时间最长,反刍咀嚼速度、逆呕时间间隔在不同月份差别不大。

Abstract: Foraging behavior of goats was investigated under different grazing pressure and different grazing time in South China.Results showed both ingesting times and ingesting steps were decreased under lower grazing pressure index,whereas bite numbers per step,rate of ingestion,intake per bite,daily intake,time of rumination were significantly increased at the same time.There was little effect on other behaviors.In September,ingesting times and ingesting steps were the least and intake per bite was maximum among all tested times.Bite numbers per step in June was significantly less than that of other months.The rate of ingestion was significantly increased in October.Time of rumination,chewing time per ruminating food bolus was the longest in October.Both chewing rate and interval time had fewer differences between two ruminating food bolus in different month.

Key words: Grazing pressure, Grazing time, Goat, Grazing behaviour, Grazing
