Extract

The poor efficiency with which ruminants utilise nitrogen (N) for growth may be due to differences in the temporal pattern of energy and protein absorption following a meal. Efficiency is higher in non ruminant animals where energy (glucose) and protein is absorbed from the same site and at the same time following a meal. Indeed, when an asynchronous pattern of energy and protein supply is imposed on non ruminants, the efficiency of nitrogen utilisation is reduced (Barja et al., 1972). The present experiment compares the efficiency of N utilisation in growing lambs given different temporal patterns of post-ruminal energy and protein supply.
