摘　　要：本研究旨在测定西藏达孜县枯草期放牧绵羊的采食量,为该县合理利用草地资源提供参考依据。借助饱和烷烃法,选用10只3~4岁放牧母绵羊为试验动物,利用饱和链烷烃作为内外源指示剂,测定了西藏达孜县枯草期放牧母绵羊采食量。结果表明,西藏达孜县枯草期放牧绵羊的平均干物质采食量为0. 89 kg/d,干物质采食量占体重的2. 23%。由此可得,利用饱和烷烃法测定放牧动物的采食量,具有较好的应用价值,通过本研究结果,结合草地产草量可知"最大载畜量",为合理利用草地资源提供参考依据。The purpose of this study was to determine the intake of grazing sheep during the dry season in daze county,Tibet. In this study,10 grazing ewes aged 3-4 years were selected as test animals by the method of saturated alkanes,and the intake of grazing ewes in daze county,Tibet was measured by using saturated alkanes as indicators of internal and external sources. The result showed that the average dry matter intake of grazing sheep in dry season in daze county,Tibet was 0. 89 kg/d,and dry matter intake accounted for 2. 23 % of body weight. It was concluded that using saturated alkanes method to determine the forage intake of grazing animals has a good application value,through the results of this study,combined with the grass yield,we can know that the‘maximum livestock capacity’can provide a reference for the rational use of grassland resources.
