【摘要】 通过应用饲养试验、消化代谢试验与比较屠宰试验,获得大量数据,经过统计分析,求得湖羊妊娠母羊、吮乳羔羊、育成羔羊、哺乳母羊及配种公羊的能量与蛋白质的需要量。同时还测出几项与制定湖羊饲养标准有关的重要参数,如每一公斤代谢体重的维持代谢能需要量(MEM/W^0.75千克)及KG与KL,后二者分别为生长代谢能（MEG）与产乳代谢能（MEL）转化为生长净能（NEG）与产乳净能（NEL）的利用系数。本研究测得湖羊的MEM/W^0.75千克,哺乳单羔和双羔母羊分别为109与119千卡、体重5、10与15千克的吮乳羔羊分别为99.5、109.6与102.6千卡,育成羔羊为93千卡,妊娠母羊为100.3千卡（2岁）和90.8千卡（3岁）;吮乳羔羊、育成羔羊与哺乳单羔母羊的KG值分别为0.68、0.31与0.70;哺乳单羔与双羔母羊的KL值分別为0.647与0.635。上述参数与国外报道的同类数值均很接近。更多还原

【Abstract】 The metabolizable energy and crude protein required by Hu-Sheep at various physiological stages of pregnancy, lactation, suckling, growing of lambs and mating rams were estimated by feeding trials, digestion tests and comparative slaughter in 1981- 85. The MEM/W^0.75 kg （metabolizable energy for maintenance of per kilogram metabolic weight） was 109 and 119 kcal for ewe of single and twin suckling lambs; 99.5, 109.6 and 102.6 kcal for suckers of 5, 1O, and 15kg live weight; 93 kcal for growing lamb; 100.3 and 90.8 kcal for pregnant ewe of 2- and 3-year-old respectively. KG （coefficient of MEG converted to NEG） was 0.68, 0.31 and 0.70 for sucker, growing lamb and ewe of single sucker, while KL （coefficient of MEL converted to NEL） was 0.647 and 0.635 for ewe of single and twin suckers, respectively.更多还原
