摘要
【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。
[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 （W^0.75）. [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.
