PREDICTION METHOD FOR METHANE (CH₄) EMISSION OF A DAIRY COW

摘要

The present invention relates to a method for predicting the methane (CH₄) emission of a dairy cow comprising: a) determining the total amount of milk of a dairy cow per one day; b) determining the energy corrected milk value (ECM) of the milk of the dairy cow of the same day as in a); c) determining the percentage amount of saturated fatty acids (SFAs) of the total milk fat of the dairy cow of the same day as in a) and the percentage amount of stearic acid (C18:0) of the total milk fat of the dairy cow of the same day as in a); d) calculating the daily amount of methane emitted by the dairy cow based on the ECM as determined according to b), the percentage amount of SFAs of the total milk fat as determined according to c) and the percentage amount of C18:0of the total milk fat as determined according to c), preferably based on regression equation 1: CH₄ [liter/day] = -1363.7 + 9.58 x ECM [kg/day] + 18.5 x SFAs[%] +32.4 x C18:0 [%] -equation1-
