N2 - This study investigated the effect of wilting and additive type on the fatty acid profile of the resultant silage. Perennial ryegrass (PRG) [Lolium] and red clover [Trifolium pratense] were cut in the field and chopped immediately post-cutting. Pure PRG, clover and a PRG/clover mix (50:50 fresh basis) were wilted for 0, 24 or 48h and ensiled with water (control), a bacterial inoculant or an acid inoculant. Total fatty acids (FA) were higher in red clover compared with PRG silages averaging 15.6 vs. 11.9 g/kg freeze dry matter (FDM) (s.e.d.=0.38; P<0.001), respectively. Averaged across all 3 forages, wilting resulted in a 15% loss in total FA, 14.6 vs. 12.4 g/kg FDM (s.e.d.=0.38; P<0.001) for 0 and 48h, respectively. Similar trends were observed for C18:3n-3. Both additives reduced total FA on average 14.4, 13.7, and 13.3 g kg-1 (s.e.d.=0.38; P<0.01) for the control, bacterial inoculant and acid inoculant, respectively.
