Feeding Directions


From birth to one year, the average weanling will increase in body weight six to seven times, building bone and muscle at an extremely rapid rate. To support this growth, young horses have increased vitamin, mineral, protein and energy needs. A lack or imbalance of proper nutrients will not support optimal growth or development. That’s why it is so important to give your weanling proper nutritional support from the start.

Hay and pasture: Controlling your weanling’s roughage intake is critical in its growing years. Hay and pasture vary considerably and can be inconsistent in digestibility and nutrient value. Of particular concern is potential deficit, excess or imbalance of minerals and vitamins.

Winter feeding: In the winter, the amount of feed may need to be increased by 10-15% to offset the increased calorie requirements of maintaining body condition.

A 6 lb meal of Equine Junior® Horse Feed supplies a full serving of Outlast® Supplement.


Purina® Equine Junior® horse feed is designed to be fed as a complete feed because it’s formulated with high-quality roughage. If necessary, you may also feed with good-quality hay or pasture – up to a maximum of 5 lbs per day – to relieve boredom. When fed with hay, reduce about 1.0 lb of feed for each 1.5-2.0 lbs of hay offered. For best results, do not feed more than 1.0 lb of hay per 100 lbs of your horse’s body weight per day when feeding Purina® Equine Junior® horse feed.

Do not feed less than 0.6 lbs per 100 lbs body weight of Purina® Equine Junior® horse feed per day to meet minimum daily requirements of protein, vitamins and minerals.


Follow label directions: feeding added selenium at levels in excess of 0.3 ppm in the total diet is prohibited.

Wash hands after feeding/handling animals.

Not for human consumption. Wash feed/water containers regularly


1. Feeding rates will vary with size, age, temperament, health status, forage quality, climate and activity level. Feed at regular times, at least twice daily. Do not feed more than 0.8 lbs/100 lbs of body weight per meal when fed without forage or more than 0.5 lbs/100 lbs of body weight per meal when fed with forage . Do not feed free-choice. Prevent rapid eating by the horse of any feedstuff.

2. Reduce and/or delay feeding a horse which is hot, excited or showing pain, has fever or diarrhea. Consult your veterinarian if any problems arise.

3. Any feed changes should be made gradually over a period of 7 to 10 days. Changes in the rate of feeding should not exceed 1.0 lb per day for each horse.

4. Provide fresh, clean water at all times. Provide your horse with access to salt. Consult with your veterinarian regularly and maintain a routine dental, parasite control and health care program for your horse.
