Extract

Feeding lambs diets formulated to be synchronous for their hourly release of energy and nitrogen (N) in the rumen has been shown to increase growth rate and feed conversion efficiency (Witt et al. 1997). However the diets used contained different feed ingredients and therefore the differences in performance may have been due to some aspect of the diet that was not characterised. The objectives of the current experiment were to supply the same quantity of feed ingredients over a 24h period but alter the sequence of allocation within the day to achieve different patterns of energy and N release in the rumen and investigate the effects on growth and metabolism of ram lambs when fed at a restricted level.
