利用404头荷斯坦奶牛的能量平衡试验资料，研究了日粮组成、采食量和产甲烷量之间的关系。所有试验中的甲烷产生都在开路呼吸室中测量。总甲烷产量的最有用的预测是可溶性残留物，半纤维素和纤维素，显然是消化的量。回归方程为甲烷（Mcal）= 0.439 + 0.273. 0.015公斤可消化可溶性残渣+ .512 .+-. 0.078 kg可消化半纤维素+1.393. ±-. 0.097千克可消化纤维素。[The系统地使用代谢能来描述反刍动物饮食的能量取决于甲烷产生的测量]。
The relationship among diet composition, intake and methane production was investigated with data during 404 total energy balance trials with Holstein cows. Methane production in all trials was measured in open circuit respiration chambers. The most useful predictor of total methane production was amounts of soluble residue, hemicellulose and cellulose that apparently were digested. The regression was methane (Mcal) = .439 + .273 .+-. .015 kg digestible soluble residue + .512 .+-. .078 kg digestible hemicellulose + 1.393 .+-. .097 kg digestible cellulose.
