This product is designed to be top-dressed on your horse's regular feed ration and/or fed as a snack within one hour prior to engaging in a potentially stressful event such as exercising, traveling, confinement, etc.
The feeding rate for both the top-dress and the snack is 20 grams per 100 to 125 lbs. body weight. For example, a 1,000 to 1,250 lb. horse would receive 200 grams of the supplement per feeding. This feeding rate is equivalent to 1.25 cups (10 ounces with a dry-good measuring cup). See chart for specific recommendations.
Typical feeding rate is 3 to 4 times per day -- top-dressed with each meal and a snack 30 to 60 minutes prior to a stressful event. Do not feed more than 6 times per day at the recommended rates for your horse's weight.
Meals of ULTIUM® Gastric Care Horse Formula or RACE READY® GT Race Horse Formula include OUTLAST® Gastric Support Supplement, so each meal will count as one OUTLAST® supplement top-dress/snack. Changes in feeding should be made gradually.
For best results, feed OUTLAST® supplement along with an appropriate PURINA® Horse Feed for your horse's lifestyle, fed at recommended rates. Provide adequate forage (minimum of 1.2% of body weight) in the overall diet to maintain normal digestive function in the horse.
Amounts of OUTLAST® Supplement to Feed Per Top-dress at Meals and/or Snacks:
Horse Body Weight (lbs.) | Supplement (grams by weight) | Number of Cups* per Meal or Snack |
---|---|---|
500 to 750 | 100 | 0.75 |
750 to 1,000 | 150 | 1.00 |
1,250 to 1,500 | 250 | 1.50 |
1,500 to 1,750 | 300 | 1.75 |

*Standard 8-ounce kitchen measuring cups when measured by volume.
Caution: 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
