Abstract: Sixteen adult and healthy ewes（ in early pregnancy）,thirteen bred ewes and thirteen bred rams from a cashmere goat farm 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 evaluate 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 goat 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.
