The economic costs of ration sorting

Sydney Moore and Casey Havekes for Progressive Dairy- April 2022 pages 24-26

The consequences of feed sorting on cow health and production have been well documented within the industry. Cows often sort in favour of smaller grain components, as these are typically the most palatable,and sort against the longer, bulkier forage components. We know when cows sort their feed, not only are they at risk of consuming an imbalanced diet, but they are also compromising the quality of feed for cows visiting the bunk later in the day. We also know sorting behaviour can negatively impact rumen health and increase the risk of ruminal acidosis. When these smaller grain components are rapidly fermented in the rumen, they abruptly lower rumen pH to potentially acidic levels.
