KEENAN understands the work that farmers need to put in every day in order to keep food on the world’s table. In such a changing landscape, the daily workload on farms is not without its challenges — unpredictability of income, rising costs, volatility of markets, legislation, changing consumer tastes and important messaging around climate change.
However, KEENAN knows that farmers are motivated, capable and multi-talented — they need to be when working in complex and unpredictable environments. Farming is also a business, and every change a farmer makes needs to pay back, in terms of profit, time-saving, herd health and safeguarding the environment for future generations.
With this in mind, a KEENAN diet feeder is a sound investment and delivers proven results through precision feeding. Our philosophy can be distilled down to one simple principle: even the smallest details can contribute to overall performance. We take the guesswork out of feeding and provide the farmer with all the tools needed to ensure consistent feed-out, nutritional support, optimised herd performance and simplified tasks that save time, all while meeting their commitment to run a low-carbon farm.
Harnessing the performance and insight of the Carbon Trust-validated KEENAN diet feeding system is a change for the better.
A KEENAN diet feeder helps mitigate against the unpredictability of income through constant returns. With precision feeding, you have oversight of productivity improvements and cost inputs.
The Carbon Trust-validated KEENAN diet feeder improves yield and herd health while reducing methane per litre produced through increased feed efficiency. This helps you play your part in safeguarding the environment for future generations.
The KEENAN diet feeder is a fully integrated system, combining build quality and technology, that helps save time and labour. Easy to use and with data at your fingertips, the KEENAN can make a real impact on your work-life balance.
Every change you make on the farm needs to pay back, and a KEENAN diet feeder enables you to make the changes you want for consistency, improved herd health and yield.
Engineered to produce an even, thoroughly mixed, light and fluffy ration, KEENAN MechFiber diet feeders are renowned across the world. Recognising that even the smallest of details can make a difference to performance, we have advanced our proven design, added additional features and improved useability to help drive increased productivity.
Yes, the KEENAN Controller can be added to any existing feeder wagon. The KEENAN Controller allows you to create the optimal physical mix.
The KEENAN Controller provides users with guidance on the order of loading and mixing, and the number of paddle revolutions required to get the optimal physical mix. The KEENAN Controller draws on KEENAN’s ingredients’ database which separates feed types into eight different categories and then subdivides each category into as many as 37 different groups. This information is then combined with the size of feeder wagon and the livestock class being fed, to provide the correct loading sequence and the paddle revolutions needed. The database currently holds over 10 million categorised ingredients drawn from over 1700 farms in a wide range of countries.
The KEENAN Controller utilises the mobile phone network to connect the feeder wagon to a secure website that can be accessed by authorised users from anywhere in the world on any web enabled device.
Feed efficiency is a very simple concept. It measures how well cows actually use the ration, and it is expressed as the litres produced per kg dry matter intake.
Compare a cow to a car. To assess how efficiently a car performs, the best measure is the miles per litre. More efficient cars go further per litre.
The same is true for cows. Instead of miles think litres, and instead of fuel, think feed. In the same way that a more efficient car will do more miles per litre, so a more efficient cow will produce more milk per unit of feed input.
With feed efficiency, what we are interested in measuring is the litres of milk produced per kgDMI, as a measure of how well the cow is using the ration and how economically they are performing. The principles apply equally when cows are housed and when they are grazing.
The beauty is that Feed Efficiency is a very easy figure to calculate as long as you know how many litres you are producing per day and how many kgDM are being fed, and these figures should be readily available. For example if the average yield per cow (Litres/cow/day) is 27 and the total dry matter fed (Kg/cow/day) is 20.25 then the feed efficiency (kg milk per kg DM) is 1.33
For ruminant animals, inconsistent and under or over mixing can impact negatively on milk yields and herd health. Under mixed and there will be sorting at the feed fence and a poor mix of long and short feed particles in the rumen. This will result in poor utilisation of the more nutritionally valuable components of the ration.
Over mixing of the ration results in small particles and fibres which promotes the rapid production of acids which can lead to a steep fall in rumen pH and a resulting acidosis. In both situations the rumen is not performing at its optimum and as a result milk yields will fall, feed will not be digested as well and cow health is at risk.
With the introduction of KEENAN’s feeding controls it has the ability to create accurate, consistent rations. It provides the means to maximise feed efficiency in a controlled and measured format.
KEENAN has gone a step further to give livestock farmers an unprecedented degree of control over a ration’s formulation, its ingredients and its mixing with the KEENAN Controller.
The KEENAN mixer wagon with the KEENAN Controller produces accurately mixed rations time after time, day after day, year after year. It intelligently removes the risk of ration variability.
Established in 1978, KEENAN is a respected leader in ethical and profitable farming solutions, focused on maximizing feed efficiency. Over the course of nearly four decades in business, KEENAN has earned a particularly strong reputation for manufacturing quality diet feeders.
KEENAN, a member of the Alltech family of companies since April 2016, feeds and interprets data from more than 300,000 cows from close to 2,000 farms in 25 countries around the world, representing one of the world’s largest field databases on dairy feed efficiency.
KEENAN prides themselves on continuous investment into new technology for the benefit of their customers globally. The company has evolved throughout the years, combining cutting-edge technological developments with breakthrough nutritional expertise.
A keen advocate for environmental sustainability, KEENAN has developed a range of solutions to enable farmers to overcome agricultural production challenges, improve rumen health and feed efficiency.
The new Balehandler Series III allows KEENAN users to quickly process all types of round or square bales. This unit can be specified on new machines or retro fitted to existing mixer wagons.
The Balehandler comprises a series of hinged metal bars which span the open top of the mixing chamber to provide a cradle to support the bale. These now have a deeper curve which not only hold the bale more securely but also exposes more of the bale to the paddles. The chopping continues within the machine using the fixed knives attached to the sides of the mixing chamber. It normally takes less than two minutes to complete which ensures that the entire bale is pre-processed before it enters the chamber.
One of the advantages of the Bale Handler is the low power, low fuel requirement – vertical auger systems which may allow whole bales to be dropped in to the mixing chamber put an enormous strain on drive lines and require high power and heavy fuel use.
And unlike this ‘one-drop’ system, the Bale Handler efficiently chops the material, usually in less time with the guarantee that the entire bale has been processed.
It is important that the mixer wagon is equipped with the technology to manage the entire mixing process, including loading sequence, quantities and mixing times. This guarantees the production of a quality mix regardless of who is operating the machine. It should be able to account for variation in types, dry matter and quality of forage. Feed efficiency is thereby greatly improved.
It is essential that the mixer wagon has a reputation for strength, durability and longevity. It may need to feed out from both sides and should be easy to drive.
Results with 31,549 cows using the KEENAN MechFiber System has shown a consistent improvement of Feed Conversion Efficiency – with increased daily yields of 1.27 litres from 0.19 kilos less feed.
The mixer wagon needs to be versatile and have the ability to handle all types of bales and forages. Can the mixer wagon possible to incorporate whole bales and has the ability to chop root crops such as beet and potatoes with ease. Water and molasses can be built-into the ration with ease.
It’s very important that the mixer wagon doesn’t grind up and damage the feeds. Having a deep tumbling mixing action is essential to ensure there are no dead spots and that the feed is not damaged.
The KEENAN mixer wagon makes it possible to prepare homogeneous rations with high fibre content for the dry cows or for small specific mixes for calves.

It is important to have a high level of quality service and parts backup. With a network of highly qualified service engineers in every market KEENAN ensure you get maximum performance from your mixer wagon.
Due to the simply gearing system in the KEENAN mixer range there are substantial fuel savings to be made. According to Paul Millican, the change from a twin auger to a bigger KEENAN MechFiber380 mixer wagon has resulted in a 50% reduction in fuel consumption. “We use a 120hp tractor to drive the mixer wagon and before the KEENAN machine arrived I needed to fill the fuel tank every week,” Paul Millican says. “ I now fill it every two weeks which means I’m saving over 600 litres a month. That’s about 7,000 litres/year which is a saving of over €4,500/year.
Having a simple drive with no gearboxes resulting in less mechanical problems and lower horsepower requirements
In order to ensure the longevity of your feeder wagon and to establish maximum performance, it is important to ensure that the machine is maintained correctly. Here at KEENAN, our expert team have compiled a quick guide of 7 tips to help you to confirm that your feeder wagon is being correctly maintained.
It is important to ensure that you do not overload your feeder wagon. Overloading it with feed, will affect the performance and will disrupt the mixing process. Overloading may even cause damage to some of the machine’s key parts. Too much weight being enforced on your feeder wagon will shorten its lifespan and cause unwarranted wear and tear. It is important that you don’t leave your wagon to sit over night or for prolonged periods with a full load of feed as this can cause premature wear and tear too.
It is important to establish that your machine size is the correct size for your herd. If your herd is frequently expanding, you may need to consider upgrading your feeder wagon. If you are using a wagon which is designed to facilitate a smaller herd size, you will find yourself having to use it more frequently and may have no choice but to overload it. Both actions will rapidly shorten the lifespan of a feeder wagon.
The feed and mixes loaded in and out of a wagon on a daily basis can lead to a considerable accumulation of dust and dirt. You must establish a cleaning schedule whereby you ensure to clean the machine regularly at scheduled intervals and log your efforts to track these actions. An accumulation of excessive dirt on parts such as bearings and chains can result in the need for costly repairs.
Just as you would with a motor vehicle, it is important to check the oil levels of your feeder wagon regularly. The oil is necessary to keep chains lubricated, which is required for optimum performance and functionality. It is recommended to change the oil in your feeder wagon at least once a year.
Regularly check your feeder for wear and tear. Prevention is always better than cure, if you can spot wear and tear on parts of the wagon, repairs will be a much less costly and timely task than replacing the parts completely. The paddles and augers of a feeder wagon can be particularly susceptible for wear and tear. Don’t forget to check the tyres also as the pressure from the weight of the loads mean that they too are susceptible to wear and tear.
To guarantee years of trouble free operation, it is important to get your machine regularly serviced by agricultural mechanics. Although you yourself may check regularly for wear and tear, only a trained agricultural mechanic may be able to spot certain key areas of damage. Treat your feeder wagon as you would a motor vehicle, by booking it in for yearly servicing, to ensure that it can run and offer the level of performance that your farm requires.
Undoubtedly, if the machine is not being set-up or used correctly, it will be more susceptible to damage and the need for repairs. It is necessary that all operators of a feeder wagon are correctly trained to operate and set-up the machine in an efficient, effective manner. If you have the KEENAN Controller, our team should be able to alert you to incorrect use or set up of the machine based on the data that we receive.
The entire process, including loading sequence, quantities and mixing times, is controlled by the KEENAN Controller. This guarantees the production of a quality mix regardless of who is operating the machine. The KEENAN Controller takes account of variations in type of dry matter and quality of forage. Feed efficiency is thereby greatly improved.

Just as you would with any other farm machinery, from time to time you may run into difficulty operating your diet feeder. There are several issues which can present themselves, many of which can be identified and resolved by you. We have compiled a list of common errors or issues which can occur with diet feeders and offer a solution by which you can troubleshoot and resolve these issues by yourself. Please note that we have developed this list with our own KEENAN diet feeders in mind, dealing with issues involving other brands of diet feeders may or may not require different actions.
If you find that the VFC door of your diet feeder simply won’t move, there are three actions to take to troubleshoot the issue:
If the VFC door keeps dropping when your diet feeder is mixing, you need to check two things:
If you find that the shearbolts of your diet feeder are consistently breaking, you need to consider taking the following actions:
If you find that the operation process of your diet feeder has become excessively loud, take the following two actions:
If your feed is not being mixed properly in your diet feeder, it may be due to:
If the feed out from your diet feeder has slowed, it usually does so because the loaded material is not chopped enough. However, if this is not the case, you need to action the following:
If the horsepower requirement of your feeder wagon becomes too high, this is usually due to:
If your feeder wagon is not chopping the feed material fast enough, this is usually due to one of three reasons:
