摘　　要：应用消化代谢实验对 6头泌乳前期的三品杂水牛日粮能量在体内的转化进行研究。结果表明 :①泌乳水牛能量消化率为 6 7 2 3% ,总能代谢率 (ME/GE)为 5 4 0 1% ,消化能代谢率 (ME/DE)为 80 2 4 % ,水牛产奶对代谢能的利用率为 36 85 % ;②可用采食总能的 10 %估算甲烷能的损失 ;③体增热为 339 5 9kJ/ (W0 75·d)。six triple crosses in the early lactating period were studied that diet energy coverts regularity in the body, used digestibility and metabolism trial The results shows: ①The digestibility of diet energy was 67 23%; The metabolic rate of general energy intake and digestible energy intake was 54 01% and 80 24% respectively; The utilization rate of metabolic energy for milk production was 36 85%; ②The methane energy was about 10% of general energy intake; ③The heat increment was 339 59 kJ/(W 0 75 ·d )
