Extract

Recent efforts to enhance the productive performance of ruminants through improved synchronisation of energy and N supplies in the rumen did not result in detectable benefits for the animals (Richardson et al., 2003). As suggested by Lapierre and Lobley (2001), the movements of N across the gut play a major role in regulating the amount of ruminally available N and provide an overall plasticity to allow rapid response to any changes in metabolic status. The objective of the present study was to examine the effects of various levels of imbalance between energy and N release in the rumen on the double-muscled Belgian Blue (dm-BB) digestion and N metabolism.
