Phileo Lesaffre Animal Care Actisaf probiotic preserves the balance of the cow's rumen ecosystem by acting in a complementary manner on the rumen biotope and microbiota. By strengthening the reductive conditions in the rumen, Actisaf encourages stabilization of the rumen pH, preventing the risk of acidosis. This action at the level of the rumen ecosystem helps to increase the digestibility of the feed, enhancing the herd's genetic potential by increasing both productivity and milk quality.
