Lower methane emissions with Rumitech

15 Jul 2021

UK based Harbro has been leading the way in methane reduction for over ten years with Rumitech.

Rumitech is a unique Carbon Trust validated feed additive comprised of natural essential oils which lowers methane emissions and improves milk yield and feed efficiency.


How it works

Rumitech alters rumen microbial populations and modulates fermentation patterns. This causes a reduction in methane emissions while also improving efficiency and performance.

The Carbon Trust has provided a validation opinion concluding that the correct use of Rumitech can reduce methane emissions in dairy, beef cattle and sheep. Rumitech was the first feed additive to achieve this status.

Improved Feed Efficiency

Rumitech not only helps cuts methane emissions but it also improves feed efficiency allowing us to get the same amount of milk from less feed or more milk from what we feed. This will also have a huge environmental benefit through reducing methane emissions per litre of milk produced.

Trial Results

Reduced dairy enteric methane emissions by 17.7% per litre of milk

Increased fat and protein corrected milk yield; +4.5% (p<0.001)

Average feed efficiency improvement; 5.5%

Typical return on investment between 5 and 10:1

How to feed

Rumitech is supplemented within minerals at a rate of 1g/hd/day. Rumitech costs 4p/hd/day when supplemented in the mineral.

The reduced enteric methane emissions benefit of Rumitech would be applied to your milking cows in your carbon audit calculations. We also see reduced metabolic disease and fertility benefits when Rumitech is fed to dry cows and throughout transition. Rumitech can also be used in youngstock and beef cattle to improve efficiency and performance.

Currently we offer Rumitech in any of our standard dairy or dry cow minerals for which we have standard and higher spec options, or alternatively we can provide bespoke minerals to match your diet with any other inclusions for a farm mineral pack.
