Purina's Omolene Horse Feeds deliver consistent, superior quality that helps keep your horse looking great. That's because no other feed company spends the time and effort researching feeds like Purina, where new products or improvements to existing feeds are only brought to market when they have repeatedly proven themselves to deliver what you expect. When you feed Purina's Omolene Horse Feed you will have the peace of mind that comes from the trust in and reputations of the Purina and the Omolene brands, which are backed by industry leading research and over 100 years of equine nutrition.

  • Fortified with Milk Components - including amino acids and polysaccharides as found in mares milk for optimal muscle growth and bone development in foals

  • Natural Whole Grains - a natural source of antioxidants, phytochemicals and fiber for lower feeding rates and designed to address digestive upset

Rated 4 out of 5 by from Nice Clean Feed But To Much Molasses I like the feed it's clean and my shetland colt loves it. But I don't like all the molasses, and high sugar/starch. So I'll be switching my colt to something else.

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.

when will omolene 200 and 300 be in tractor supply that contain the product outlast which provides gastric support When looking at the bags of feed they now have in the store it does not show that the feed contains outlast

Asked by: horsered
Thanks for choosing Purina. The product went into circulation the first week of September in most areas. As the older product is used up, you will begin seeing the new reformulated Omolene bags hit the market place. It all depends on the TSC store warehousing and how much they have stocked. Once you see the look of the new bag, you will know you have the Outlast in the product.

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.
