Horse owners should take precautions when grazing pastures after the first killing frost. Frost damaged pasture species can have higher concentrations of nonstructural carbohydrates, leading to an increase in the potential for founder and colic, especially for horses diagnosed with EMS, PSSM, laminitis, obesity or Cushings. To reduce the chances of adverse health effects, we recommended horse owners wait one week before turning horses back onto a pasture after the first killing frost.
