Why Keenan Are Different


Keenan have leading internationally acclaimed scientists, agricultural economists, nutritionists and engineers working together to deliver superior performance on farm.


Keenan machines are a masterpiece of engineering. Keenan engineers manufacture the most efficient, durable, high performance feeder wagon possible.


In 2005 the Keenan scientific advisory board was founded. It consists of world renowned specialists in the areas of animal science, nutrition and economics.

Quality of Product:

Keenan use quality components, leading technology and a Right First Time (RFT) process to create a mixer wagon that performs better than any other.


Keenan has patents on all our mixer wagons, the mixing technology and also the specific ration structure which is produced from a Keenan.

greater feed conversion through our farm solutions

Balanced, Efficient Farming to Minimise Environmental Impact

As our global village grows, and as climate change introduces new and difficult challenges for agricultural production, adopting integrated technologies which address inefficiencies in production without compromising our environment become an imperative. Keenan is the first of its kind to offer such a solution to the livestock industry - a solution that is real and verifiable.


Keenan works with a many partners across the world. These include large international feed companies, processors, consultants and nutritionists. By working with partners who have specialist skills and common goals we can bring win-win solutions to farmers. Programs such as Gain Plan bring together the best expertise, knowledge and technology to deliver maximum on farm results.

Gain Plan for Maximum Results

Gain Plan is a collaborative program between Keenan and its global partners to bring win-win solutions to farmers.

Proven By Independent Research Studies

Scientific proof from Illinois showing the benefits of Keenan over a tub mixer

“Our research showed that Keenan mixes had more optimal particle size and were less variable than the same rations produced in a vertical mixer wagon. These led to only small differences in rumen pH and yet we found convincing evidence that the rumen environment was altered favourably in Keenan-fed cows.

As a result, the efficiency of converting feed to milk solids was significantly improved for cows fed with the Keenan mix leading to substantial improvement in income over feed costs”.

Reading Research proving that cows fed with a Keenan produce more milk

“Cows fed a TMR prepared with a Keenan Mech fiber® mixer, produced 1 additional litre of milk/d (40.3 v 39.3litres/d) and additional milk protein, compared with the same cows fed the same feed ingredients in a TMR prepared using a vertical auger mixer.Continuous measurement of rumen pH showed Keenan fed cows spent 28% less time below 6.0”

The Keenan Mech-fiber System is discussed as an opportunity to improve farm profitability, feed efficiency and animal health.

This study showed that milk increased by 1.74 kgs/cow/day with DMI reduction of 0.64kgs/cow/day.

"For those who want to improve their profitability and are risk adverse, the Keenan Mech-fiber System is dominant over other feeding systems" - Robert Jolly
