As previously stated “the objective of feeding a total mixed ration (TMR) is to provide a consistently uniform mix, with the intended ingredient and nutrient composition, across the entire length of the feedbunk with every batch.” And while a number of factors such as ingredient variability and moisture content, consistency of mixing procedures, operator error, and weighing system variability contribute to batch-to-batch variation, it is the characteristics of the mixer itself that essentially control within batch variation, and uniformity across the feedbunk. In this article we will discuss TMR mixer characteristics that affect mix uniformity and a sieving technique that can be used to evaluate it and make adjustments to improve animal performance.
Go to any farm equipment show, or “surf” the internet, and you will see there are a wide range of makes and models of TMR mixer on the market today, which can make selecting the right one for you a bit confusing. In this issue we will look at the origin and key differences between the two main classifications of mixers that are available today, namely, Horizontal and Vertical mixers.
