UNH study links weather extremes with clover traits

 

The New Hampshire Agricultural Experiment Station at the University of New Hampshire has unveiled significant findings on the impact of extreme weather on phytoestrogen levels in clover species used in dairy farming.

Their research indicates that red clover, a staple in Northeastern dairy farms, doubles its phytoestrogen content during drought conditions, potentially disrupting cow fertility and farm productivity. 

This increase is seen as a natural defense mechanism of red clover against environmental stress. However, it poses challenges for dairy farmers dealing with the reproductive health of their cows, which is crucial for milk production and farm revenue.

Alternatively, kura clover, which thrives in varied climatic conditions and poor soils, maintains consistent phytoestrogen levels even under similar stress, suggesting it as a viable alternative for sustainable dairy farming in regions prone to extreme weather.

The findings underscore the importance of selecting appropriate forage crops that can withstand environmental challenges without compromising the health of dairy livestock. This research is part of ongoing efforts to equip farmers with the knowledge to adapt to increasingly unpredictable weather patterns, ensuring the sustainability of dairy operations in the Northeast and beyond.

Video: Four Star Pork Industry Conf - Back to Basics: Fundamentals drive vaccine performance

At a time when disease pressure continues to challenge pork production systems across the United States, vaccination remains one of the most valuable and heavily debated tools available to veterinarians and producers.

Speaking at the 2025 Four Star Pork Industry Conference in Muncie, Indiana, Dr. Daniel Gascho, veterinarian at Four Star Veterinary Service, encouraged the industry to return to fundamentals in how vaccines are selected, handled and administered across sow farms, gilt development units and grow-finish operations.

Gascho acknowledged at the outset that vaccination can quickly become a technical and sometimes tedious topic. But he said that real-world execution, not complex immunology, is where most vaccine failures occur.
