🚨 PSA for Horse Owners Buying New Hay 🚨
As many of you begin sourcing hay from new suppliers—especially from out of state—we want to share an important reminder to protect your horses.
We are seeing an increase in hay-related issues coming from other regions, including:
• Toxic weeds (such as hoary alyssum, which can cause limb swelling, fever, and laminitis-like symptoms)
• Blister beetles in alfalfa, which can be life-threatening if ingested
• Mold, dust, and poor fermentation leading to respiratory issues or colic
• Nutritional inconsistencies that can impact performance, weight, and overall health
⚠️ Before feeding new hay:
• Inspect each load closely for weeds, mold, and foreign material
• Smell for musty or sour odors
• Introduce new hay gradually over 7–10 days
• When possible, request a forage analysis
• Know where your hay is coming from and how it was harvested
Even high-quality-looking hay can carry hidden risks—especially when sourced from unfamiliar regions or during challenging growing seasons.
If your horse shows any unusual signs after a hay change (fever, swelling, colic, decreased appetite, or lameness), contact your veterinarian right away.
