| [目的]研究滩羊羔羊的能量需要,为制定滩羊饲养标准奠定基础.[方法]选择1日龄滩羊羔羊30只,1～15日龄全母乳喂养,每日定时哺乳5次;16～30日龄,每日定时哺乳4次,并补饲.测定羔羊每日哺乳量和饲补饲料采食量,估算羔羊每日能量摄入量,建立能量摄入量与日增质量(ADG)、代谢体质量(W0.75)之间的回归方程.[结果]利用建立的回归方程,估算得到不同体质量、不同日增质量水平下消化能(DE)、代谢能(ME)的营养需要量.[结论]滩羊独特的品种特征和主产地的生态环境条件,决定了其能量需要量相对较其他品种大,尤其是维持需要的能量相对较高. |

| Abstract: |
| 【Objective】 The determination of feeding standard for Tan sheep lamb was studied based on energy requirements. 【Method】 30 neonatal lambs were suckled 5 times per day within 15 days,4 times and also complementally fed in 16-30 days.Daily milk consumption and supplementary were measured to evaluate energy intake in order to establish regression equation of energy intake,average daily gain（ADG）and metabolic weight (W0.75).【Result】 Digestible energy (DE) and metabolic energy (ME) requirements were determined according to the regression equation in different weights and different daily gains of Tan sheep lamb. 【Conclusion】 Tan sheep energy requirement is more than other species,especially maintain energy requirement (MEr),according to the unique breed and growing environment. |
