Feeding instructions:
Feed at regular times. Do NOT feed over 5.0 lbs of Omolene #300 Horse Feed in one serving. Divide total daily feeding into at least two servings with three daily servings preferred. Be sure to weigh your feed using a scale. Feed horse in a natural position from troughs placed at normal head height or lower. Do NOT feed free-choice (all the horse wants). Reduce and/or delay feeding a horse that is hot, excited or showing pain, fever or diarrhea. Consult your veterinarian if any problems arise. Prevent rapid eating. Always feed a minimum of 1.0 to 1.2 lbs of body weight of good quality, clean hay or pasture. Inadequate amounts or poor quality hay may lead to colic and other digestive disturbances. Have plenty of fresh, clean water available at all times, except immediately after intense physical activity. Provide your horse with access to salt. Maintain a regular deworming program, have the horse's teeth examined annually and consult your veterinarian on a regular basis. After observing the horse for a period of time, the amount fed may be increased or decreased by 10% to obtain the desired body condition and weight. More specific recommendations may also be obtained from a Purina Horse Feed sales representative. Please consult the tag sewn onto this bag for complete feeding recommendations.

Will this product help an older horse gain weight 

Asked by: Old age
Thanks for choosing Purina. It does depend on the ability your older horse has to chew and digest hay. Omolene 300 is formulated to meet the needs of the young, growing foal and lactating horse. Your better choice will be the Equine Senior which can replace some, or all, hay if necessary. Feel free to give us a call if you would like to discuss in more detail. We can be reached at 1-800-227-8941.

How much would you feel a miniature horse foal?

Asked by: Little Legends
For a mare in foal, we would suggest to feed the Omolene 200 or 300 at a rate of 0.3 lbs. per each 100 lb. in body weight during the first 250 days. In the last trimester you will feed 0.5 lbs. for each 100 lbs. in body weight per day. While in lactation, the average is 1.1 lbs. for each 100 lbs. in body weight per day. You will want to monitor body condition and let that be your best guide in how much to increase the amounts. Give us a call if you have any additional questions at 1-800-227-8941.
