Abstract

The aim of this study was to investigate variation in phytoestrogen concentration in different varieties of red clover and the variation over the season. Eighteen varieties of red clover (12 diploid and 6 tetraploid) were sown in duplicates in a plot experiment in 2014. All plots were harvested four times a year in the growing season of 2015 and 2016. Samples were analysed for eight different phytoestrogens. Total amount of phytoestrogens decreased during the season. It was 86% higher in spring growth than in the third regrowth. Phytoestrogen composition also changed during the season. Differences between varieties
were consistent over season and year, and the variety with the highest concentration had a concentration 57% higher than that with the lowest concentration. The considerable variation in phytoestrogen concentrations among varieties presents opportunities for selection of varieties with low concentrations for use when a high inclusion of red clover is required in ruminant diets.
