Scottish innovation achieves international success

14 Jun 2019



Maxammon is a grain treatment process that improves rumen performance and digestibility and as a result, leads to improved feed efficiency. With the resulting benefits including significant increases in production, both in terms of liveweight gain and improved milk yield, as well as improved health and fertility, Maxammon can make a huge impact to the overall performance of any ruminant.

R&D investment

At Harbro, we’ve been working with and developing our Maxammon technology for more than 10 years. During this time we’ve partnered with 14 universities and research institutes in 8 countries across the globe to rigorously test and develop the product to ensure that ruminants from a diverse range of systems can use it to obtain the best nutritional response. We’ve also invested in an extensive in house testing and quality assurance programme and have a full time member of staff dedicated to the product.

With a decade of farm success across the UK, Maxammon farmers throughout Scotland regularly host visits from international groups keen to find out more about the product. And this global appeal has meant the product is now sold both direct and through distributors across five continents and in over 20 countries spanning the globe where farmers report the same health and performance benefits that have been seen within the UK.

New improved Maxammon formula

Following comprehensive testing in our laboratories and grain treatment sites, Harbro is pleased to announce a new improved Maxammon formula, which will be available from June 2019. The new formula has enhanced activity and improved ammonia production rates – the key factors which drive the rumen efficiency, feed conversion and the overall performance benefits of Maxammon.


Proven success in cattle

Independent trials by leading agricultural organisations across the globe have shown consistently high performance across a variety of breeds and systems using the Maxammon approach.

A recent trial co-ordinated by the University of Milan Veterinary Sciences department compared a Maxammon maize and maize silage based diet to a standard high energy, maize and maize silage based diet with equivalent levels of protein. The results showed:

  • Improved daily liveweight gain - daily liveweight gain was significantly higher in the Maxammon group.
  • Improved feed conversion efficiency - feed conversion in the Maxammon group was 5.4% better than the control group.
  • Significantly more stable rumen pH.
  • Improved rumen health and lower instances of acidosis and bloat.


Feeding Maxammon to dairy cows

One farmer who has seen the benefits of using the Maxammon Feeding System for a number of years is Gavin Baillie who milks 250 pedigree Holstein cows:

“Before we started feeding Maxammon 5 years ago, we always struggled to feed more than 4.5kg of our own cereal and instead had to rely on soya hulls and a rumen buffer to keep the rumen safe.  However, since feeding Maxammon we now feed up to 8.75kg of cereal along with protected rapeseed and molasses, which has not only lifted our starch and sugars from 21% to 27.5% but also reduced the amount of soya we are feeding by over 2kgs.  Dung consistency and fertility is excellent with the herd currently averaging 10,500kgs on twice a day milking and with some of the highest milk qualities we have ever had with

  • milk butterfat up to 4.27%
  • milk protein up to 3.58%.


Maxammon feeding systems include:

  • Treating suitable grain at harvest time or dried, stored grain throughout the year – maize, wheat, barley and oats. Wholecrop, straw and pulses can also be treated.
  • Supply of Maxammon grain direct to farm
  • Supply of Maxammon blended feed and compound.
  • We also offer a complete Maxammon processing service for farmers looking to home treat.

Back to basics

With harsh market conditions and Brexit uncertainty focussing minds on increasing efficiency and sustainability, the Maxammon system allows for simple rations to be created from forage and home grown cereals allowing for optimised performance and profit at the same time as controlling cost.
