The KEENAN Controller

Their latest innovation – the KEENAN Controller – takes the approach to feed to a whole new level.  Although KEENAN do offer a nutrition support service this is not essential to get the most from the machines so, if you prefer, you can use an independent nutritionist to help manage your feed requirements.

Thanks to the KEENAN Controller, your nutritionist is able to send instructions on the feed mix remotely to the Controller, including how long to mix it for, ensuring that the approach is the same every time.  The InTouch Daily TMR Manager software then enables the farmer and nutritionist to see what has been used and to keep track of costs, as well as providing detailed graphs and reports on ingredients used, feed costs, herd productivity and feeding accuracy.
