Abstract

A urfia-formaldehyde-molasses complex appeared to be a promising slow ammonia-releasing urea derivative in in vitro studies. It was compared with urea-molasses mixtures as a non-protein nitrogen supplement to an ad libitum wheat chaff ration for steers. The significantly lower (P < 0·01) crude protein digestibility and intake of digestible crude protein, and the non-significantly lower nitrogen retention on the urea-formaldehyde-molasses complex ration revealed the superiority of simple urea-molasses mixtures as a non-protein nitrogen supplement.
