Abstract: The ewes of Liaoning cashmere goats were introduced into Pu-wa goat Ranch, Fang-Shan county, Beijing, during a period of 24 months in 1990 1992 for the study of intake.based on grazing days.The results showed that: intake of 4.32 ±0.84kg of fresh matter per day per an ewe body weight of 32.2 kg duting growth season, and 2.91 ± 0.69kg of dead matter per day per an ewe body weight of 36.5kg during nongrowth season.The variation of intake were sig nificant between months, and a relative stability during other months.

摘要： 1990～1992年对北京市房山区蒲洼乡绒山羊种羊场引入的辽宁绒山羊成母羊进行三个年度24个月份的放牧日采食量测定,研究其月际间动态规律。结果表明;在牧草生长季节,平均32.2公斤体重的成母羊,鲜草日均采食量为4.32±0.84公斤,以五月份的来食量最高。在枯草期平均体重36.5公斤的成母羊,枯草日均采食量为291±0.69公斤。干物质年均采食量为1.79±0.41公斤,为其体重的5.26%。鲜、枯草采食量月际间变化明显。干物质采食量以11月份最高,其余各月份变动幅度不大,并保持相对稳定的数量。
