摘 要：
选择舍饲东北细毛羊生长期公羊6只,按体重分为2组,第1组:(26.9±3.39)kg,第2组:(34.85±0.35)kg,应用开放式呼吸测热装置进行了绝食72～96h气体呼吸测热试验及消化代谢试验研究。结果表明:第1组和第2组的耗氧量为(8.89±0.59)和(9.53±3.44)L/W0.75·d;CO2生成量为(7.44±0.45)和(6.7±1.10)L/W0.75·d;绝食期间呼吸商为0.71,0.67;粪氮排泄量为(0.17±0.06)和(0.14±0.08)g/W0.75·d;尿氮排泄量为(0.42±0.11)和(0.24±0.11)g/W0.75·d。

摘 要：
Six house-feeding male northeast fine wool sheep in growing stage were selected and divided into 2 groups according to their bodyweights. The bodyweights of Group 1 were (26.9±3.39) kg and that of Group 2 were (34.85 ± 0.35) kg. The gas respiratory calorimetry experiment and digestive metabolism experiment were performed on the sheep fasting for 72～96 h by applying respiratory calorimetry equipment with open circuit. The results indicated that the oxygen consumption quantities of Group 1 and 2 were (8.89 ± 0.59) and (9.53 ± 3.44) L/(W0.75·d),their creation quantities of CO2 were (7.44 ± 0.45) and (6.7 ± 1.10) L/(W0.75·d),their respiratory quotients in fasting period were 0.71 and 0.67,their fecal nitrogen excretion amounts were (0.17 ± 0.06) and (0.14 ± 0.08) g/(W0.75·d) and their urine nitrogen excretion amounts were (0.42 ± 0.11) and (0.24 ± 0.11) g/(W0.75·d).
