Belgium: research on feed conentration of dairy cows

In Belgium research by the Flemish ILVO institute shows that cows that get less concentrate feed after 80 days in lactation use this more efficiently. Cows that got 1 kilogram of concentrate per 1.7 kilogram of extra milk and heifers that got 1.6 kilogram of concentrate per extra kilogram of milk were compared with 1 kilogram of concentrate per 3 kilogram of extra milk. With cows this did not result in a lower milk production, fat or protein content. In heifers it did. However: other effects, such as fitness, health and fertility, were not considered.
