目的是准确量化首次泌乳奶牛肠道甲烷（CH4）排放量，并利用这些数据建立CH4预测方程。利用量热计测量和生产数据计算了荷斯坦-弗里斯（HF, n = 32）和挪威（n = 32）头泌乳奶牛305 d的CH4排放量。在高精料饲粮中，HF和挪威人的甲烷产量相似（123 vs 126 kg/305 d），但在低精料饲粮中，HF的甲烷产量高于挪威人（105 vs 98 kg/305 d） （P < 0.05）。饲喂高精料日粮的HF，其血清中磷含量较低(P <。05)每能量校正产奶量CH4排放量（16.3 g/kg）高于其他3个处理（19.7 ~ 20.4 g/kg）。然后利用这些数据建立CH4预测方程，为估计HF和挪威第一泌乳奶牛肠道CH4排放量提供了另一种方法。
Abstract The objectives were to accurately quantify enteric methane (CH4) emissions for first lactation dairy cows and to use these data to develop CH4 prediction equations. Calorimeter measurements and production data were used to calculate CH4 emissions for Holstein-Friesian (HF, n = 32) and Norwegian (n = 32) first lactation cows during a 305-d lactation period. Methane outputs were similar between HF and Norwegian (123 vs. 126 kg/305 d) when offered high-concentrate diets, but HF produced more CH4 (P < 0.05) than Norwegian (105 vs. 98 kg/305 d) when given low-concentrate diets. The HF offered high-concentrate diets had a lower (P < .05) CH4 emission per energy-corrected milk yield (16.3 g/kg) than the other three treatments (19.7–20.4 g/kg). These data were then used to develop CH4 prediction equations, which provide an alternative approach to estimate enteric CH4 emissions for HF and Norwegian first lactation dairy cows.
