*Feeding IMPACT® PRO SENIOR with forage: Good quality hay or pasture may be fed along with IMPACT® PRO SENIOR. Make sure your horse is free of dental problems and can effectively chew and utilize the forage. Reduce the amount of IMPACT® PRO SENIOR by 1 lb for every 1.5 to 2 lbs of hay consumed by your horse.

Do not feed less than 0.7 lbs per 100 lbs of body weight of IMPACT® PRO SENIOR per day to meet minimum daily requirements of protein, vitamins and minerals. Feeding recommendations are based on average daily requirements for horses of different body weights. Actual feeding rates required to adequately maintain good condition of individual horses will be affected by individual metabolism and progression rate of aging processes. Therefore, feeding rates may need to be gradually adjusted in some horses according to body condition.
Store in a dry, well-ventilated area protected from rodents and insects. Do not feed moldy or insect infested feed to animals as it may cause illness, performance loss or death. USE ONLY AS DIRECTED.
