Black oil sunflower seeds (BOSS) are a popular, nutritious supplement for horses, known for boosting coat shine, weight, and condition due to their high (40-50%) oil content, omega-6 fatty acids, and vitamin E. They are safe to feed in moderation, generally at 100g-450g per day, without exceeding 800g-1kg per day to avoid upsetting the omega-3 balance.

Key Considerations for Feeding BOSS to Horse
What to Feed: Use whole, raw black oil sunflower seeds, commonly sold for wild birds, rather than striped sunflower seeds (which have tougher hulls).
Benefits: High in fat for energy, enhances coat, hoof quality, and provides magnesium. Nutritional Limitations: Low in the essential amino acid lysine; they should be used as a supplement, not a main protein source. Feeding Rates: Safe amounts are typically 100–450g per day, with a maximum of 800 kg Precautions: They are high in omega-6 fatty acids, so they may need to be balanced with omega-3 supplements (like flaxseed).
