| 本试验对12只西农莎能奶山羊泌乳羊一些行为进行了昼夜24小时的连续观测。结果表明,昼夜采食时间为245.67±56.81分钟,食后反刍来临时间为76.42±22.47分钟,反刍时间为534.83±79.30分钟,反刍周期数为19.25±2.38次,昼夜共反刍551.42±87.19个食团,咀嚼速度为1.23次/秒,咀嚼次数为32681.95次,反刍多在夜间卧地进行。昼夜采食与反刍时间的比值为1:2.29。昼夜游走和站立的时间为400.53±166.25分钟,昼夜卧息时间为583.92±145.76分钟,昼夜差异极显著(P<0.01)。昼夜睡眠时间为145.33±62.80分钟。昼夜排粪、尿的次数分别为45.67±15.26、10.92±3.03次。昼夜躺卧比站立、游走时间稍长。争斗之间个体差异很大,变异系数为130.67%。以上结果可为西农莎能奶山羊的推广、疾病诊断及制定科学的饲养管理制度提供参考。 |

| Abstract: |
| The continous observation was made on the behaviours of 12 Xinong Saanen milk goats for 24 hours in a day and night in their lactation period.The results obtained from the observation showed that food intaking time was 245.67±56.81 minutes in 24 hours of a day and night.After 76.42±22.47 minutes of food intaking,the ruminating started,with the ruminating time being 534.83±79.30 minutes and the ruminating cycles being 19.25±2.38 times.Chewing speed was 1.23 times/second with a chewing frequency being 32681.95 times.Rumination frequently occured at night in the recumbency position.Ratio between food intaking and rumination was 1：2.29,and their moving and standing time was 400.55±166.25 minutes day and night.Resting in fecumbency position was 583±145.76 minutes in 24 hours,but there was a significant difference between day and night(P<0.01).Their sleeping time was 145.33±62.80 minutes and the frequency of urine and dung discharg is 45.67±15.26 and 10.92±3.03 day and night respectively.Their lying-down time was longer than that of standing and moving about. Fighting difference among the individuals was very significant with a coefficient of variation being 130.36 percent.In this way,the above-observed results can be regarded as an important reference for extension,disease diagnoses and working-out of scientific managment system for Xinong Saanen Milk goats. |
