摘  要：
用不同形态的大针茅草产品(草颗粒、草块、草粉、未做处理的干草)对乌珠穆沁羊进行饲喂试验,对其采食和反刍行为进行观测。结果表明:供试羊舍饲饲喂大针茅草颗粒时,24h平均采食时间为343.45±25.07min,总反刍时间为564.61±11.73min,反刍食团数534.96±35.41个,反刍周期24±1.05个,每个反刍周期持续时间和逆呕食团数分别为23.53±1.20min和22.29±1.10个,每个食团的咀嚼次数和时间分别为92.06±0.83次和55.34±1.76s,2个食团吞咽逆呕间隔时间为8.00±0.52s,反刍食团咀嚼总次数为49 248.42±3706.14次。天然大针茅加工成不同形态草产品后,草颗粒是饲喂乌珠穆沁羊的最适草产品形态。

摘  要：
The effect of Stipagrandis product(grass diet pellet,grass block,grass powder,particles,and grass hay without any treatment)on grazing and ruminating behavior of Ujumqin sheep was observed.The results showed that when the sheep were fed with grass diet pellet of Stipagrandis,the average grazing time was 343.45±25.07 min and total average ruminating time was 564.61±11.73 min a day,ruminating diet ball numbers were 534.96±35.41,ruminating cycle numbers were 24±1.05,duration time of each ruminant cycle was 23.53±1.20 min,and diet ball inverse number in each ruminant cycle was 22.29±1.10,times and time chewing a diet ball were 92.06±0.83 and 55.34±1.76 srespectively,the interval time between two diet ball swallowed and inverse vomiting was 8.00±0.52 s,total times of chewing ruminated diet ball were 49 248.42±3706.14.The optimal grass product of Stipagrandis was pellet for feeding Ujumqin sheep.
