UNH explores drought impact on clover phytoestrogens

UNH explores drought impact on clover phytoestrogens


By Jamie Martin

A recent University of New Hampshire study highlights how extreme weather, particularly drought, affects the phytoestrogen content in red clover, commonly used in Northeast dairy farms.

The research, conducted by the New Hampshire Agricultural Experiment Station, observed that phytoestrogen levels in red clover could double under drought conditions, potentially affecting dairy cow reproduction and farm economics significantly.

Red clover is favored for its nutritional benefits in dairy farming but poses risks when phytoestrogen levels spike during droughts.

In contrast, kura clover, known for its resilience to diverse weather conditions, showed no increase in phytoestrogen levels, marking it as a potentially safer alternative amidst changing climate patterns.

The study not only sheds light on the adaptive responses of different clover species to environmental stresses but also underscores the need for farmers to consider alternative foraging options as extreme weather events become more frequent.

With the Northeast experiencing more variable weather, understanding how forage crops respond is crucial for dairy farm management and sustainability.

As researchers continue to explore the factors influencing phytoestrogen levels in clovers, the findings can help inform more resilient agricultural practices, ensuring the health of livestock and stability of dairy production in the face of climate change.
