敖汉细毛羊5月龄公羔舍饲行为观测

于2007年8月,采用焦点取样和连续记录方法,对全舍饲情况下5月龄敖汉细毛羊公羔的行为进行了昼夜连续观察.结果表明:敖汉细毛羊公羔,全天用于反刍的时间最长,达(519.37±14.27)min;而采食、走动、站立和休息时间分别为(326.43±5.44)、(94.67±10.41)、(98.18±12.97)和(357.69±14.91)min.敖汉细毛羊公羔的行为具有昼夜节律性,用于采食、反刍时间均为夜间大于白天(P<0.01);而走动(P<0.01)、休息(P<0.01)和站立(P>0.05)时间则是白昼大干夜间.反刍与采食时间比为1.59:1.00,昼夜反刍总食团数为(581.83±45.57)个.对于该品种绵羊行为的了解有助于提高其在舍饲条件下的管理水平.

Abstract：

By the methods of focal sampling and all occurrence recording, a continuous observa-tion on the behaviors of 5-month old Aohan fine-wool male lambs under stall-feeding was conduc-ted day and night in an experimental sheep farm in August 2007. The male lambs spent (519.37 ±14.27) min·d~(-1) for ruminating, (326.43±5.44) min·d~(-1) for eating, (94.67±10.41)min·d~(-1) for moving, (98. 18±12. 97) min·d~(-1) for standing, and (357. 69±14.91) min·d~(-1) for resting. A diurnal rhythm was observed in the behaviors of the lambs, i.e. , the time foreating and ruminating was longer at night than at daytime, while that for moving, resting, and standing was longer at daytime than at night. In the whole day, the time ratio for ruminating to for eating was 1.59: 1.00, and the total number of ruminated cuds was 581.83±45.57. Under-standing the behaviors of the male lambs would help to the improvement of management practices for rearing Aohan fine-wool sheep under stall-feeding.
