Fractionation of forage legume crops can make a protein-rich feed available for monogastric animals. The aim of the current study was to assess the effect of fractionation method, leaf stripping or juice production, in lucerne (Medicago sativa) on protein yield in low-fibre fractions. We established field trial with replications on two lucerne varieties in Menemen, Turkey, in 2018. At first cut in 2019 whole plant and six different fractions were processed and sampled. Across varieties, juice, leaves and leaf juice yields accounted for 45%, 53% and 24% of the whole plant dry matter yield, respectively. Crude protein content was higher in leaf juice (26%) than whole plant juice (23%) and the content in leaves differed between the varieties (22% and 27%). Leaf stripping separated a higher proportion (on average 70%) of the total crude protein in the plant than juice production (on average 55%). The effects of variety, harvesting time and number of cut need further investigation.
