Advantages of Actisaf

In Dairy Cattle: Improves dry matter intake during feed transitions, pasture entry and high-grain feeding. Especially during early lactation, it helps increase milk yield.

In Beef Cattle: Enhances feed conversion ratio (FCR), improves carcass and meat quality, and supports live weight gain.

In Calves: Promotes early rumen development and reduces digestive disorders.
