为探明川中黑山羊（乐至型）在舍饲条件下的营养需要量，为其标准化养殖以及饲料资源的合理利用提供参考，在四川省乐至天龙农牧科技有限公司种羊场选择同类型体重相近、健康无病的川中黑山羊（乐至型），测定舍饲条件下的采食量，并对主要养分摄入量与山羊饲养标准进行比较。结果表明：在羊舍温度20．34～39．12℃和相对湿度55％～100％条件下，生长羔羊、空怀母羊、妊娠前期母羊、妊娠后期母羊、泌乳母羊、后备公羊和种公羊的干物质采食量分别为0．74 kg/d、1．47 kg/d、1．62 kg/d、1．72 kg/d、2．12 kg/d、1．91 kg/d和2．27 kg/d，干物质采食量占体重的比例分别为3．63％、2．92％、3．09％、3．23％、4．45％、3．03％和2．96％。生长羔羊、泌乳母羊、后备公羊和种公羊的消化能摄入量能满足需要，空怀母羊的偏高，妊娠前期母羊和妊娠后期母羊的不足；粗蛋白摄入量除泌乳母羊不足外，其他类型山羊均偏高；钙和磷的摄入量均偏高，且钙磷比例不平衡。建议，调整精料配方组成和饲喂日粮的精粗比，以满足川中黑山羊（乐至型）的营养需要，促进其生长发育。

In order to prove up the nutrients need of Sichuan black goats (Lezhi type)under drylot feeding condition, and to provide references for standardization of culture and rational utilize of feed resource,each stage’s feed intake of Sichuan black goats(Lezhi type)under drylot feeding condition that were healthy with similar body weight in alike stage and fed in Sichuan Lezhi Denon agriculture and animal husbandry science on technology limited breeding farm was determined respectivly,and primary nutrients intake were compared to feed standard.The results indicated that under the environmental conditions of that the average temperature and relative humidity was 27.01℃(20.34~39.12℃)and 84%(55%~100%),and the DMI of growing lambs,non-pregnant ewes,early gravid ewes,late gravid ewes,lactating ewes,backup rams and adult stock rams were 0.74 kg/d,147 kg/d,1.62 kg/d,1.72 kg/d,2.12 kg/d, 1.91 kg/dand 2.27 kg/d,respectively.DMI weight ratios were respectively 3.63%,2.92%,3.09%, 3.23%,4.45%,3.03%,2.96%.The digestible energy (DE)of intake by growing lambs,lactating ewes, backup rams and stock rams could meet the demand;but the DE of non-pregnant ewes was on the high side,besides,the experimental data of early gravid ewes and late gravid ewes was insufficient.Except the goats during lactating,the intake of CP by other stages of goats exceeded the needs,the intake of calcium and phosphorus by all stages of goats exceeded the demand,and the ratio of calcium and phosphorus was imbalanced.Therefore,the constitute of concentrate formula and concentrate to forage ratio should be adj usted to satisfy the nutrients need of Sichuan black goats(Lezhi type)and boost its growth.
