The agriculture industry is responsible for a significant amount of greenhouse gas emissions, and cow burps are one of the main culprits. It’s a well-known fact that cows produce methane through their digestive process, however, did you know that the amount of methane produced by cows has been steadily increasing since the turn of the century?

Researchers have found that capturing and storing cow burps can reduce greenhouse gas emissions by up to 30 percent—a number that’s particularly impressive when you consider that many other methods don’t even come close to this level of effectiveness.

In this article, we’ll look at how researchers are working with farmers and ranchers to implement new technologies and practices in order to tackle this issue head-on.

Why does livestock cause such a problem to the environment?

Cow burps produce a lot of methane, which accelerates climate change because cows are ruminants, which means they have a long digestive tract. The microorganisms that live in their stomachs are able to break down cellulose, a tough carbohydrate found in plants.

The main reason cow burps produce a lot of methane is because their digestive system is quite different from those of humans. Cows are ruminants, and their stomachs have four chambers: the rumen, reticulum, omasum, and abomasum. The first three chambers contain a thick mass of microbes that break down food as it moves through the cow’s digestive tract.

These microbes produce methane as they digest plant material in the first chamber, which is why some farmers add carbon dioxide to a cow’s feed to increase the amount of methane they produce. This process also makes it easier to extract the gas from a cow’s manure without having to collect it all manually!

When cows burp, they release methane and CO2 into the air. Methane is a greenhouse gas that traps heat in the atmosphere and can accelerate climate change, and it’s estimated that around 100 million tons of methane are released from livestock each year—which is about 14% of total global emissions.

Which countries have the largest livestock?

The word ‘livestock’ refers to the animals that are raised for meat or milk and includes cattle, pigs, poultry, sheep, and goats. It also includes the use of animals as draft animals and beasts of burden.

The world’s largest livestock producers are China (cattle only), Brazil (cattle only), the United States (beef only), and the European Union (cattle only). Other major players include Australia (cattle only), India (cattle only), and Russia (cattle only).

The U.S. ranks third among cattle-producing nations at 96 million head of cattle where the cattle industry is a $100 billion industry in the United States. It’s also one of the largest contributors to greenhouse gas emissions in the country.

The world’s largest cattle-producing countries are India and Brazil, with more than 200 million head of cattle each.

China is another country with large numbers of cattle. The FAO estimates that there are about 200 million cows in China, which make up about 20 percent of all cows worldwide.

How Vaccines may reduce GHG?

Vaccines will change the way we think about cow emissions. Right now, cows produce an enormous amount of methane gas through their flatulence and belching. This gas is harmful to the environment, so it’s important that we find a way to reduce its effects on our planet.

In order to reduce the harmful effects of methane on our environment, scientists are developing a vaccine. This vaccine aims to achieve the potential to significantly decrease methane production in cattle without affecting their health or growth rates. It will work by preventing the formation of methanogenic archaea (MA) in the rumen, which is responsible for producing methane gas through fermentation. By preventing MA formation within cattle’s stomachs, we can decrease methane production by up to 60%.

This vaccine could help us make great strides towards mitigating climate change by reducing harmful greenhouse gases like methane.

How diet could help reduce a cow’s methane production?

A new study from UC Davis working with a Swiss AgriTech startup called Mootral has found that feeding cows certain diets can lower their methane production.

Mootral is an innovative feed supplement that naturally reduces methane emissions.  Mootral is made up of two natural ingredients: garlic powder and citrus extracts. Garlic is a natural antibiotic, and it helps fight off parasites in the gut. Citrus extracts have been shown to reduce bacteria in the stomach, which can help lower methane emissions.

Mootral has been proven to reduce methane emissions, thereby reducing greenhouse gas emissions. It is intended to be added to a cow’s daily feed ration. The researchers say it works by inhibiting methanogens, or bacteria that produce methane in the cow’s stomach. So, Mootral can be used as an additive to any ration or used as a complete feed for beef cattle and dairy cows.

The UC Davis study was conducted on two commercial farms in California. On one of them, Mootral was added to all of the cows’ daily feed rations; on the other farm, half of the cows were fed with Mootral while half were fed without it. At both sites, greenhouse gas emissions were measured before and after introducing Mootral into their diets.

At both farms, researchers found that when cows consumed Mootral, they produced roughly 20% less methane than when they did not consume it—a reduction of about 99%.

Mootral’s ability to reduce greenhouse gas emissions makes it an effective tool for policymakers who are looking for ways to meet national targets and caps set by the Paris Agreement on climate change. By using policy and legislation, national targets and caps on greenhouse gas emissions can be enforced in order to achieve these goals.

Governments and policymakers can support innovation for a green future by using policies and legislation, national targets, caps, and incentives as well as penalties. For example, the European Union has created a framework to limit methane emissions from dairy cows. The legislation includes provisions to reduce greenhouse gas emissions from livestock farming by 20% by 2030. This is an example of how governments can use policies to drive positive environmental change in the food industry.

In addition, incentives can be used to encourage farmers to use Mootral on their farms by providing financial support through subsidies or tax breaks; this would further increase its impact on reducing emissions over time as more farmers use it in place of traditional feeding methods (such as feeding livestock grain).

Methane capture solutions help to limit emissions

A UK-based company has developed a potential solution in the form of a burp-catching face mask for cows, designed to reduce methane emissions from cattle by 60 percent. The mask is designed to be worn by a cow when it is digesting food. The company, Zelp, says that the masks will also help keep cows cool in hot weather and reduce stress on the animals.

The mask is fitted with a tube that leads from the cow’s mouth to an air filter that sits next to their stomach. The device allows cows to belch in comfort while also trapping the gas and preventing it from escaping into the atmosphere.

The device has a sensor at the tip of the mask that detects when a cow exhales and the amount of methane that is exhaled. Farmers and academics can utilize this information to reduce greenhouse gas emissions from cows.

The company says its masks are made from biodegradable plastic and fit over the animal’s heads while they’re eating or chewing grass. “We have found that this is an effective way of catching the gas before it can escape back into the atmosphere,” said Zelp CEO Lee Smithson. “The gas then gets pumped through a pipe into an underground storage tank.”

The company claims that if all cows wore the masks worldwide, they could reduce global methane emissions by 1 billion tonnes every year. This would be enough to slow down climate change by two years.


Capturing and limiting methane production from cows is a viable method of reducing livestock related greenhouse gas emissions. By collecting and storing the gases produced by cows, we can reduce the amount of methane they emit into the atmosphere and reduce their overall impact on climate change. Additionally, there are other benefits to this method of collecting cow gas, including a reduction in manure odor and improved health for dairy cows.
