摘要
对１６只中卫山羊母羊的青草期和枯草期反刍行为进行观察表明：山羊在青草期，每天（２４ｈｒｓ）有１０个反刍周期，反刍持续总时间为３０４．２分，共反刍４２５．３次，每个食丸在口腔中咀嚼４３．０秒，共咀嚼４６．４次；在枯草期上述指标分别为１１个，４２０．０分、４７２．０次、５３．４秒和５９．６次。季节对山羊反刍行为的影响，本质上决定于羊采食牧草的品质和数量．优质牧草（青草期）能够缩短反刍持续总时间（Ｐ＞Ｏ．０１）及每次反刍的时间（Ｐ＜０．０１）．减少反刍总次数（Ｐ＜０．０５）人每次反刍的咀嚼次数（Ｐ＜０．０１）：粗劣牧草（枯草期）的作用则相反。
Sixteen does of Zhongwei goat were used in the observation and
resarch.Within24hrs during green grass season,there were 10 ruminant poriodicities,the total
duration was304.2 min,there werc 425.3 times ruminant,the duration for chewing one cud was
43.0 sec,and the numbers for chewing one cud were 46.4 times.During withered grass
season,theabove-mentioned items were 11,420.0 min, 472.0 times,53.4 sec and 59.5 times
respectively. The effects of seasons on ruminant behavior in goat depended on the essential
distinctions ofqual ity and quantity of grass on the arid,scmi- desert grassland.High-quality
grass(greenseason)can shorten the total duration of rumination(P<0.01)and the average
duration per rumination (P<0. 01),and decreased in the total ruminant ofper quality
grass(withered season)turned out contrary to rumination of goat.
