Whole groundnut plants were ensiled without or with 5, 10, 15 or 20% formaldehyde (5 litres/t). There was no significant difference in pH (5.56 to 5.70) among treatments. Ammonia concentration decreased significantly with all formaldehyde treatments which suggested a protective effect on protein nitrogen degradation to non-protein N. There was no difference in lactic acid fermentation between treated and control silage. Propionic acid and ethanol concentrations were decreased in all treated silages. It was concluded that 5% formaldehyde was sufficient for protection.
