摘　　要：用传统开路式牛用呼吸面具对 18 月龄母水牛绝食产热(FHP)进行研究。结果表明:①18 月龄母水牛 FHP 为328 55 kJ/(kgW0 75·d);每天排出EUN为33 19 g;单位代谢体重每天排出EUN为0 46 g;蛋白分解产热占总产热量为16 46%;尿氮(EUN)与FHP比值为1 46 mg/kJ。②18月龄母水牛维持净能需要:NEm=410 69 kJ/(kgW0 75·d)。Fasting metabolism of 18 months old female buffaloes was studied by traditional open-circuit respiration hoods. The result showed that the Fasting Heat Production(FHP) of 18 months old female buffaloes was 328.55 kJ/(kgW 0.75 ·d). Endogenous Urine Nitrogen(EUN) excretion per day was 33.19 g;EUN excretion of per unit metabolic body weight per day per head was 0.46 g;There was 16.46% protein catabolic Heat Production in Total Heat Production. The ratio of EUN to FHP was 1.46 mg/kJ.The result also showed that the requirement of maintenance net energy at 18 months old female buffaloes was NEm=410.69 kJ/(kgW 0.75 ·d).
