Extract

Lucerne hay or silage is major forage fed to dairy cows in Iran. During fermentation, a large proportion of the CP in lucerne (L) is broken down to NPN; typically, 50 to 60 % to more than 80 %. Therefore, broken down of true protein in lucerne silage (LS) to NPN substantially reduce efficiency of CP utilization in lactating cows (Broderick et al., 1995). The objective of the present experiment was to compare the nutrient content, and in situ DM and protein degradability of LS treated with urea and HCl.
