18 dairy cows and other cattle are in a farm. find the CFP of this animals due to enteric fermentation

To calculate the Carbon Footprint (CFP) of the dairy cows and other cattle due to enteric fermentation, we need to know the specific emission factor for each type of cattle. The emission factor is the average amount of greenhouse gases (in this case, methane) that a single animal produces per year due to enteric fermentation.

According to the IPCC (Intergovernmental Panel on Climate Change), the emission factor for dairy cows is about 119.6 kg of methane per year and for non-dairy cattle, it's about 53 kg of methane per year.

However, from your question, we don't know how many of the 18 cattle are dairy cows and how many are other types of cattle.

Let's assume 'x' are dairy cows and 'y' are other cattle.

So, x + y = 18

The total emissions from the cattle would be (119.6x) + (53y) kg of methane per year.

To convert this to a carbon footprint, we need to multiply by the global warming potential (GWP) of methane, which is 25. This means that methane is 25 times more potent as a greenhouse gas than carbon dioxide.

So, the total carbon footprint would be 25 * [(119.6x) + (53y)] kg of CO2 equivalent per year.

Without knowing the exact numbers of dairy cows and other cattle, we can't calculate a specific carbon footprint.
