摘要： In ruminants, urea recycling provides a mechanism by which N may be salvaged into bacterial matter that may be digested by the animal to supply amino acids for production purposes instead of excreting it in the urine. Therefore, the urea-N salvage mechanism could be a very important key to increase N efficiency in ruminants (Stewart and Smith, 2005). The objective of the present study was to determine the effect of ruminal degradable N (RDN) level on nutrient digestion and N metabolism in growing bulls fed beet pulp silage based diet in order to minimise N excretion in the environment and maximise N retained by the animals.
