In winter and summer, relationship between grazed plants and fatty acid (FA) content in milk and herbage was studied in grazing goats. Milk and herbage FA profile, pasture botanical composition and herbage intake were evaluated. In both seasons, Gramineae was positively correlated (pc) with CLA and C18:1trans in milk fat. Gramineae showed a negative correlation (nc) and pc with LA and LNA in herbage, respectively. Forbs were pc with MUFA and LA, nc with C18:1trans and LNA. Dactylis glomerata was pc with unsaturated FA in winter and with CLA in both seasons. Lolium perenne showed pc with PUFA and LNA, nc with C16:0 and LA. Phleum pratense was pc with MUFA and nc with saturated FA and summation-omega-6 in milk fat. In both seasons, pc was observed between MUFA, summation-omega-3 and herbage intake. LA and LNA content in herbage exhibited nc and pc with PUFA and C18:1trans in milk fat, respectively
