The pH level in the rumen drops considerably if a large amount of quickly fermentable feed is ingested once or twice a day. This can cause subclinical rumen acidification, which damages the rumen wall. The forage can pass through the rumen too quickly, as the bacteria that ferment the raw fibre are inactive if the pH level is too low, resulting in poor digestion of roughage.
The ideal scenario is for cows to eat 10 to 14 smaller portions every 24 hours. This will maintain proper and stable pH levels, ensuring optimal fodder usage. Increasing both the feed frequency and feed pushing frequency will encourage cows to visit the feed fence more often. Offering smaller portions reduces the possibility of cows selecting feed, which also has a positive effect on pH stability in the rumen. In addition, it means more frequent consumption of fresh and tasty feed at the feed fence.
