pH values show you how basic or acid the rumen is. Rumen pH values are highly sensitive and directly influenced by feeding. This is why this parameter is the best to assess and optimize feeding.
The goal is to have rumen conditions that are as stable as possible. Because: The more stable the pH values, the better the preconditions for an efficient rumen flora.
Rumen pH is the scientifically recognised gold standard in detection of subacute rumen acidosis (SARA). Depending on the country, research shows that up to 50% of fresh and high lactating cows can suffer from SARA.
In this case, the pH value is at least 300 minutes per day below 5.8. SARA can barely be detected from the outside and thus often passes unnoticed, even though it leads to numerous secondary diseases and problems as well as significant financial losses. With continuous pH measurement, subacute rumen acidosis can be detected precisely and thus can be avoided.
