STUDIES ON RUMEN METABOLISM

Abstract
The results obtained in this study can be summarized in the following:
1. Protein sources in this study (SBM, CGM and CSM) had no effect on digestibility coefficient of nutrients. Urea supplementation caused an increase in EE digestibility coefficient but it decreased CF digestibility coefficient.
2. No •significant differences were detected among protein sources regarding DMI. Urea supplementation resulted in reduction of DMI for CGM (1159.29) and CSM(1151.77), but this was not the case for SBM (1349.37).
3. SBM diet had higher (P<0.05) TDN (%) value either it was supplemented with urea or not. Supplementation with urea resulted in slight decrease in TDN value for CSM. DCP value (%) was increased for CGM supplemented with urea, but it decreased with the other two protein sources (SBM and CSM).
4. Similar NI was observed for all diets irrespective of source of protein or supplementation with urea. SBM with or without urea had higher NB followed by CSM diet without urea. Urea supplementation resulted in lower NB for CGM and CSM. However, urea supplementation increased the nitrogen utilization of SBM by sheep.
5. Values of rumen pH were increased 3h post-feeding and decreased again 6h post-feeding.
