Extract

During the ensiling process, even under good conditions, some of the plant proteins are broken down to soluble nitrogen compounds which are less well utilized by the ruminant. Formaldehyde, alone (Wilkins, Wilson and Woolford, 1974) or in conjunction with formic acid (Wilson and Wilkins, 1980), has been used as a silage additive to protect proteins against degradation during ensilage. Glutaraldehyde (Mangan, Jordan, West and Webb, 1980) has been suggested as an alternative due to its rapid fixing action and in this experiment it was compared with formaldehyde.
