摘 要:在夏季自由放牧的条件下,选择昭苏马场针茅+杂类草的草甸草原草地,对体况相近健康无病的3只5月龄伊犁哈萨克公羊的放牧行为进行昼夜跟踪观察。结果表明:昼夜的采食时间为481.05±29.03 min,占总活动时间的33.40%,反刍和卧息的时间分别为498.24±31.69和248.17±16.03 min;反刍与采食的时间较为接近。昼夜反刍周期数9.00±2.97,反刍周期持续时间19.77±9.98 min,每个食团咀嚼时间46.82±2.51 s,反刍咀嚼速度1.59±0.05次/s,昼夜排粪、排尿次数分别为8.44±1.33次和5.56±1.59次。A successive observation was made on the diurnal grazing behavior of three healthy 5-month age Kazak rams in summer under the free grazing. The results showed that the duration of their intake at daytime and night was 481.05±29.03 min, occupying 33.40% of the total duration of their activities,and the rumination,crouch and sleeping were 498.24±31.69 and 248.17± 16.03 min respectively. There was little difference between rumination time and intake time: The duration of diurnal rumination was 9.00± 2.97,the duration of rumination period was 19. 77±9.98 min,each diet ball for chewing was 46.82±2.51 s; and the speed of rumination chewing was 1.59±0.05 times/s; the diurnal defecation and urination were 8.44±1.33 and 5.56±1.59 times respectively.
