  1. Based on live weight determined at the beginning of each period, 6 animals were fed at 40%, 60%, 80% or 100% of their maintenance energy requirements (MER) over 4 periods in a crossover design. Treatment periods were 35 days and were preceded by a 14-day feed-up (100% MER) to minimise any carry-over effect. Sampling was carried out in the fourth week of each treatment period
