Testing for Nutrient ContentBy Kentucky Equine Research Staff · January 14, 2015
When Kentucky Equine Research is involved in studies that require testing for nutrient content, samples of feed, urine, and feces are taken each day. Feed and fecal samples are then chemically analyzed for dry matter, crude protein, acid detergent fiber, neutral detergent fiber, lignin, fat, starch, water-soluble carbohydrates, gross energy, ash, and minerals. Urine samples are analyzed for crude protein and minerals. The minerals of interest are calcium, phosphorus, potassium, sodium, magnesium, chloride, iron, zinc, copper, manganese, and molybdenum.
