Method for evaluating the amount of methane produced by a dairy ruminant and method for decreasing and controlling this amount |
| 摘要 |
The present invention relates in particular to a method to evaluate the quantity of methane produced by a dairy ruminant. The method comprises determination of the ratio between the quantity of fatty acids with 16 carbon atoms or less and the sum of the total fatty acids of the milk, said quantity of methane being defined by the following equation: Quantity CH4=(FA<C16/Total FAs)*a*(milk production)b in which: quantity CH4 (in g/litre of milk)=quantity of methane produced; FA<C16=quantity of fatty acids with 16 carbon atoms or less; Total FAs =total quantity of fatty acids; expression of the ratio (FA<C16)/(Total FAs) as a % of total FAs; milk production=quantity of milk produced in kg of milk/animal and per year; a and b are numerical parameters in which a lies between 10 and 13, and b lies between −0.40 and −0.45. |
