The most important greenhouse gases from the livestock industry are methane and nitrous oxide.
- How to reduce methane emissions in livestock
Reduce methane emissions from Cows by:
Adjusting cattle’s diet with ingredients that are easily digestible and
absorbed. Using feed efficiently.
In 2019, scientists conducted an experiment by adding 1%
easily digestible red seaweed to the diet of cows. The result was a reduction in methane emissions
of up to 60%.
Selective breeding of fast-growing cattle Scientists believe that,
faster-growing cattle breeds will need less feed and produce a significant
amount of milk. This will help reduce methane emissions.
Chemical to limit methane production: Dutch medical company Royal DSM
has developed a chemical to limit methane production.
Methane vaccine: In recent years, researchers in New
Zealand have identified the gene of a microorganism that lives in the stomachs of cattle
that specializes in producing methane. If we could “attack” these bacteria
with a vaccine – they claim – we would have an effective vaccine against methane.
Today, the construction of modern biogas digester models by farms has contributed significantly
to reducing greenhouse gas emissions.
Reducing NH3and H2S gases in manure:
In Korea, MGMJ. Co. Ltd. has created the MG Catalyst Water filter
Softener combined with a herbal catalyst solution, which significantly reduces
the odor of NH3 and H2S at hundreds of pig and chicken farms in this country. This helps shorten the composting process to 7 days.
The lifetime greenhouse gas emissions of a pig are 0.67 (t-CO2eq).
with the MG Energy Water technology, the turnover rate is improved from 2.0 to 3.1
times/year. If the turnover rate increases by 34.3%, the greenhouse gas reduction based on
50,000 pigs is 35,620 t-CO2eq/year.
- How to reduce emissions in feed mills
Reduce dependence on fossil fuels by choosing natural
energy sources such as solar and wind.
Using new raw materials such as by-products, seaweed products,
insects in feed formulation: Many projects have been implemented in Europe such as
the Multi-Str3eam project, SUStainable INsect CHAIN has been implemented to develop
new protein sources.
Focusing on 3 main topics: feed sources, feed production
and feed solutions. The goal is to reduce 75% CO2 / ton of feed.
Developing software to calculate emissions related to the processing of
raw materials and to be able to calculate the carbon footprint of each individual feed product
: Alltech and for Farmer have developed the Feed print software and applied it to calculate input materials.
Optimizing technology and production lines: helps save fuel and
emissions.
There are still many measures and applications being researched and applied by scientists,
companies in the future with the common goal of
protecting the earth.
