Maize grains undigested

HARD maize grains in some of this years silage are passing through cows rumens without being digested, according to feed compounder Bibby.

He suggests balancing rations with rapidly fermentable energy sources such as sugar or digestible starch to improve its utilisation.

Rumenco recommends using a molasses blend that is high in fermentable energy and protein to pre-treat maize silage. It claims that this will trigger enzyme breakdown and encourage digestion.
