Hi Penny,

I think that feeding Glanzen would be an excellent choice since you would be providing flaxseed meal, along with the vitamins and minerals it offers. I would recommend the Glanzen-SE since it has selenium, since you plan on eliminating the other selenium product. Glanzen SE does not have a bad odor.

I'm not sure why you want to feed Quiessence in her case. I generally recommend it for horses who are prone toward laminitis (insulin resistant due to overweight) or horses who are high strung and need more magnesium in their diet. It will not protect against laminitis due to feeding large amounts of oats.

The reason large amounts of oats (starch) can lead to laminitis is because of the amount that does not get digested and ends up in the hind gut for the bacterial flora to ferment.

Rice bran is a good choice -- make sure it is a product that contains added calcium, such as Natural Glo by ADM Alliance.

But, oat hay is not very nutritious and feeding large amounts of oats will not only endanger her health, but will not give you the weight gain you're after.

If you can add alfalfa pellets to her diet, this will be helpful. And, flaxseed meal (from the Glanzen), along with rice bran, will be your best bet. Do no feed more than 3 lbs of oats each day. It's a good idea to weigh your feed to know exactly how much you're feeding -- scoop sizes are unreliable.

I would also suggest that you give her Ration Plus to help her gain weight. This is a very effective way to boost the health of her digestive system so she gets more calories from her forage.

I hope this is helpful. Oh -- one other very important thing -- make sure her teeth are healthy. Teeth problems are a major cause of weight loss.

All the best,
