摘　　要：试验选择陕北白绒山羊繁育中心羊场的成年健康母羊(怀孕前期)16只,育成母羊13只,育成公羊13只,空腹称重。测定每只羊1 d的采食量,计算其摄入的营养成分含量,并与原苏联绒用山羊饲养标准比较,进行饲养水平评价。结果显示,与饲养标准比较,陕北白绒山羊繁育中心羊场的育成母羊代谢能高2.68 MJ,粗蛋白低59.29 g,钙低3.00 g,磷低1.52 g;育成公羊代谢能高3.47 MJ,粗蛋白低81.92 g,钙低4.42 g,磷低2.62 g;成年母羊代谢能高2.51 MJ,粗蛋白低91.33 g,钙低3.09 g,磷低1.93 g。结合羊的体况综合评价饲养水平基本合理,但尚需要按饲养标准增加粗蛋白、钙、磷等营养物质的供给量。Sixteen adult and healthy ewes （ in early pregnancy）, thirteen bred ewes and thirteen bred rams from a cashmere goat fiarm of the breeding center of Shanbei area, were selected and weighed in fasting state. The food intake and nutrient content for each goat for a day were measured and calculated, respectively. Then the data was compared with the Cashmere goat breed standard of the former Soviet Union to evalu- ate the feeding level. The results showed that, compared with the Cashmere goat breed standard of the former Soviet Union, the metabolic energy in the bred ewes was 2.68 MJ higher than the Cashmere goat breed standard, and the contents of crude protein, calcium, and phosphorus in the bred ewes were 59.29 g, 3.00 g and 1.52 g lower than the Cashmere goat breed standard, respectively; the metabolic energy in the bred rams was 3.47 MJ higher than the Cashmere gnat breed standard, and the contents of crude protein, calcium, and phosphorus in the bred rams were 81.92 g, 4.42 g and 2.62 g lower than the Cashmere goat breed standard, respectively; the metabolic energy in the adult ewes was 2.51 MJ higher than the Cashmere goat breed standard, and the contents of crude protein, calcium, and phosphorus in the adult ewes were 91.33 g, 3.09 g and 1.93 g lower than the Cashmere goat breed standard, respectively. The feeding levels for the bred ewes, bred rams and adult ewes were basically reasonable through comprehensive evaluation based on the body condition of Shanbei white cashmere goats, but there was still a need to improve the supply of crude protein, calcium and phosphorus, and other minerals for Shanbei white cashmere goat.
