Biochar cattle feed can offer a great benefit to your livestock. They can benefit from a number of advantages such as improved daily grain and feed efficiency, as well as a reduction in the amount of methane your cattle emit. Using biochar in your cattle feed will also help reduce the amount of antibiotics that your animals are exposed to.

Mechanisms by which biochar reduces cow methane emissions
Biochar has been studied for potential use as a feed additive to reduce methane emissions from cattle. It is an organic material that is made by charring biomass. However, its effects on ruminants are not well understood.
Methane is a potent greenhouse gas that makes up about 90% of all livestock greenhouse gas emissions. It is 25 times more potent than carbon dioxide.
Methane is produced by methanogens in the rumen. These bacteria are key in methane production. They are also responsible for the degrading of cellulose. In addition to that, they can also remove metal oxides, nitrates, and sulfate from the rumen. While they are present at low levels, they can be suppressed or inhibited by inhibitors. This could explain how biochar can increase their abundance.
Although many studies have suggested that biochar can decrease methane emissions from cows, only a few have investigated its effect on ruminants. A few have found no effect, while others have found a range of reductions.
Improved daily grain and feed efficiency
Biochar is a byproduct of the pyrolysis of plant biomass. Typically, the process involves heating the material to a temperature of 350-600 degC. The resulting solid carbon residue is commonly referred to as “char.”
As an additive, biochar has been shown to improve the digestion and absorption of nutrients by animals. It may also absorb unwanted pollutants. However, studies on the use of biochar in diets are limited. Therefore, more research is needed to understand its effects in vivo.
For example, researchers examined the effects of enhanced biochar on methane emissions and rumen fermentation. They found that addition of a 0.5% BC treatment decreased CH4 production in finishing steers. In addition, a 5% biochar amendment increased feed intake and feed conversion ratio.
Enhanced biochar is a pyrolysed form of charcoal. It is mixed with other inorganic nutrients. This is done in order to enhance its degradation potential. Additionally, the presence of a BC enhances composting.
Potential to replace antibiotic treatment in chicken and ducks
There is a lot of interest in using biochar as a feed additive. Biochar is a form of carbon produced from pyrolysis of organic materials. It has been used for centuries in animal and human medicine, for example in treating digestive disorders.
It is also known to be useful as a greenhouse gas sequestration agent. When used as a feed additive, it has potential to reduce GHG emissions from manure management and fertilizer usage. This has been studied in cows, chickens and pigs.
While most of these studies have been conducted on the effects of biochar on livestock and poultry production, there is not yet enough data to evaluate the impact on overall health and well-being. Nevertheless, there are some promising results.
One of the main benefits of biochar as a feed additive is its ability to reduce nutrient losses. As a result, farmers can cut the mineral N-fertilizer usage. Moreover, it has a positive secondary effect on soil fertility.
Potential to replace antibiotic treatment in pigs
Biochar is a type of organic carbon-rich materials that can be used as a feed additive in animal farming. It can promote nutrient efficiency and sequester carbon. Since 2010, biochar has been used as a regular feed additive in animal farming.
The benefits of biochar are well known. Biochar can increase composting efficiency, enhance soil fertility, reduce greenhouse gasses, and decrease phytotoxicity of compost. Moreover, it can act as a potential substitute for antibiotic treatment.
Biochar is made by pyrolysis of organic carbon-rich materials. It has similar properties to charcoal. In animal farming, biochar has been applied since 2010. However, the use of biochar in livestock feed is limited. To date, only a few studies have been conducted.
In this study, we analyzed the effect of biochar inclusion on the growth and bacteriostasis of pigs. We measured changes in absolute abundances of intI1 and intI2 during pig manure composting. Furthermore, we evaluated the electrically conducting property of biochar using a method described by Fu et al. in 2021.
