Fibre Requirement For Dairy Cows
Cows will need a certain amount of fibre in the diet to ensure their rumen functions properly. Here are some of the minimum fibre requirements:
Neutral Detergent Fiber: 30% DM
Acid Detergent Fibre: 19% DM
Crude Fibre: 17% DM
Low fibre, high starch diet will cause rumen to be acidic.
Acidosis may occur.
In order to minimize this, adding sodium bicarbonate will help to reduce acidity.
Buffers such as sodium bicarbonate are highly recommended when grain feeding per day exceeds 4 - 5 kg grain/cow.
Buffers are not a substitute for fibre, hence feeding low fibre diets should be avoided.
