Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Cattle release what type of greenhouse gas as a result of fermentation in their digestive tract?
A
Oxygen
B
Carbon Dioxide
C
Phosphorus
D
Methane
Explanation: 

Detailed explanation-1: -Enteric methane emissions from ruminant animals raised for their meat and milk account for as much as 30% of global anthropogenic methane emissions, and factors such as feed quality, animal size, and environmental temperature will increase the amount of methane an animal produces if left unchecked.

Detailed explanation-2: -1 agricultural source of greenhouse gases worldwide. Each year, a single cow will belch about 220 pounds of methane. Methane from cattle is shorter lived than carbon dioxide but 28 times more potent in warming the atmosphere, said Mitloehner, a professor and air quality specialist in the Department of Animal Science.

Detailed explanation-3: -Manage manure to reduce greenhouse gas emissions. Livestock urine and manure are significant sources of methane and nitrous oxide when broken down under anaerobic conditions. Nitrous oxide is produced during the nitrification–denitrification of the nitrogen contained in livestock waste.

Detailed explanation-4: -Methane is the main greenhouse gas produced in grazing systems. Ruminant livestock (cattle, sheep, and goats) have microbes in their rumen called methanogens. These microbes produce methane (from the fermentation of feed) that is then belched out.
