The silages, offered ad libitum, were of first cut, and to achieve the higher protein content additional pure red clover silage was added in a mixer wagon prior to feeding. The low protein silage was 95% dominated by timothy and meadow fescue. Concentrate type did not affect silage intake. Cows fed concentrate without protein supplement had a lower milk yield but a higher milk fat content (P
