对33只不同品种及不同生理阶段的舍饲山羊测定日采食量,并参照美国NRC(1981)山羊营养需要标准进行营养盈缺分析,结果表明:山羊日粮代谢能为9.35～10.20 MJ/kg时,山羊干物质采食量占体重百分比为2.3 %～3.7 %,接近或高于标准.山羊每日摄入的粗蛋白质、钙和磷数量明显超过标准;公羊、空怀母羊日摄入代谢能高于标准,而妊娠母羊、哺乳母羊和波杂育成羊日摄入代谢能水平接近NRC标准或缺乏.

The paper reports an analysis on surplus and deficiency of nutritive matter of goat in the confined condition according to the goat requirement of NRC(1998). The analysis collects datum of food intake of 33 goats which consisted of three kind in different period. The results indicates the food intake is 2.3 %-3.7 % of body weight when metabolic energy(ME) of the concentrate change between 9.35-10.20 MJ/kg, that is close to or high than the standard of NRC, and the daily intake of crude protein, calcium and phosphor is higher than the standard , the daily intake of ME in billy goat and nanny goat in non-pregnant is higher than the standard too, the daily intake of ME of diet of nanny goat in pregnant, in lactation and crossbred Boer goatling is close to the standard.
