Extract

Extensive enzymic degradation of proteins in grasses during ensiling, as well as the ease with which the remaining proteins are degraded in the rumen is undesirable. Formaldehyde has bacteriostatic properties, and can protect plant proteins from degradation in silage and in the rumen (Henderson, 1993). Tannins form complexes with proteins and may protect silage protein and improve amino acid utilization in ruminants. Earlier results with tannins (Salawu, et al, unpublished data) were promising but inconclusive because of poor fermentation. Silage fermentation can be improved by the use of formic acid (Barry, et al, 1978). The aim of the experiment was to compare the effect of tannins [quebracho tannins (QT) and mimosa tannins (MT)] or formaldehyde (F) or formic acid (FA) or a mixture of tannins/FA or formaldehyde/FA on silage composition.
