Extract

Monensin, an ionophore, and AO, a fungal feed additive, are growth promoters which modify rumen fermentation. Previous studies have shown that monensin increased propionate, the efficiency of bacterial growth and the flow of protein from the rumen and decreased methane production and fibre digestion (Schelling, 1984), whereas AO increased bacterial numbers and fibre digestion and lowered methane production (Frumholtz et al., 1989; Fondevila et al., 1990). The aim of the present study was to determine, using Rusitec, the effects on rumen fermentation of combining these additives.
