Do I really need a hay analysis?
Short answer
Yes! Hay is the foundation of most equine diets. Without testing, supplementation is guesswork. A hay analysis details protein, energy, mineral levels, and non-structural carbohydrates (NSC), which are an especially important consideration for metabolic horses.
Real-Life Example
If a horse gains weight easily and seems metabolically sensitive, one may assume that low-starch feed and supplements to support metabolic tendencies are needed. Not knowing the hay’s NSC or mineral profile could lead to over-supplementing, missing a deficiency, or feeding higher sugar than realized!
It Depends
A hay analysis is truly necessary, but especially important if:
• Your horse has EMS, IR, or PPID
• You’re managing laminitis risk
• Your horse is a hard keeper or easy keeper
• You’re adding multiple supplements
• You want to balance minerals precisely
When to Seek Guidance
Work with a veterinarian or equine nutritionist to interpret results, or if your horse shows:
• Unexplained weight gain or loss
• Poor hoof quality
• Behavioral changes (increased lethargic states or discomfort)
• Recurrent metabolic concerns
