摘要/Abstract

摘要： 在夏季自由放牧加补饲的条件下，对体况相近健康无病的4只4月龄南江黄羊公羊的放牧行为进行昼夜跟踪观测。结果表明:南江黄羊4月龄公羊，昼夜采食时间为513.75 min，占总活动时间的35.68%，而反刍、走动、站立和卧息的时间分别为289.00、113.00、89.75和361.50 min。采食时间、站立时间、排粪尿时间、游走时间和争斗次数均为白天大于夜间，而反刍时间和卧息时间则是夜间大于白天。反刍与采食时间比为0.56:1.00，昼夜反刍总食团数为422.25个。该品种羊耐粗饲，采食快，抗逆性强，对各种气候条件有良好的适应能力。

Abstract: A successive observation was made on the diurnal grazing behavior of four healthy 4-month old Nanjiang yellow goat rams in summer. The rams were free grazing at daytime, and supplemented with concentrated forage at night. The results showed that the duration of their intake at daytime and night was 513.75 min, occupying 35.68% of the total duration of their activities, and that of rumination, stroll, standing, and sleeping was 289.00, 113.00, 89.75, and 361.50 min,respectively. The duration of intake, standing, excretion and stroll were longer and the frequency of fighting was more at daytime than at night, while the duration of rumination or sleeping was shorter at daytime than at night. The duration ratio of rumination to intake was 0.56:1.00, and the total number of ruminated cuds at daytime and night was 422.25. Nanjiang yellow goat was approved to be fast intake, good in tolerance, and able to bear low quality forage and various climate conditions.
