摘　　要：用传统开路式牛用呼吸面具对12月龄母水牛绝食产热(FHP)进行研究。结果表明:①12月龄母水牛FHP为334.03KJ/KgW0.75·d;每天排出内源尿氮(EUN)为31.06g;代谢体重每天排出EUN为0.53g;蛋白分解产热占总产热量为17.99%;EUN与FHP比值为1.60mg/KJ。②12月龄母水牛维持净能需要:NEm=400.84KJ/W0.75d。Fasting metabolism of 12 month-old female buffaloes was studied by traditional open-circuit respiration hoods. The result showed that the Fasting Heat Production (FHP) of 12 month-old female buffaloes was 334. 03 KJ/kgW0.75d. Endogenous Urine Nitrogen (EUN) excretion per day was 31. 06g; EUN excretion of per unit metabolic body weight per day was 0. 53 g; There was 17. 99% protein catabolic Heat Production in Total Heat Production. The ratio of EUN to FHP was 1. 60 mg/KJ. The result also showed that the net energy requirement for maintenance of 12 month-old female buffaloes was NEm = 400. 836 KJ/ w0.75d.
