Abstract: The aim of this study was to evaluate the qualitative characteristics, microbial profile and nutritive value of high-moisture orange pulp co-ensiled with poultry by-product meal (PBM) or urea as additional nitrogen (N) source. The optimum dry matter (DM) content of each experimental silage was achieved by adding the appropriate proportion of wheat straw. A control silage was also prepared with orange pulp and wheat straw, but without any supplemental nitrogen. Each experimental silage was ensiled in three replicates of 12 kg mini-silos and left intact for 90 days. The evaluated traits were: silage pH, microbial population, lactate, acetate, butyrate, crude protein (CP), true protein and NH3 -N contents. In addition to these, in situ dry matter and CP degradability as well as ruminal and post-ruminal CP disappearance rates were also measured. Both N-supplemented silages showed higher pH values and CP contents compared to the control silage (P
