Adding oil to your horses' diet

We receive calls through our nutritional helpline every day from people asking a multitude of questions on how to keep their horse looking, feeling and performing the best. This month, we have had a lot of enquiries about how to feed oils to their horse - hear what our Nutritional Advisor, Cosette Darby has to say

Id like to give my ex racehorse oil in his feed. He is 17hh weighs 600 kgs. He appears to be down in weight and not alot of energy. I have canola oil purchased from the supermarket. Is this fine to give him. How much do I start him out on. Is it true this can give him diarrhea at first?
Thankyou from Trish

Linseed oil is better than other oils as it has more good omega 3 fat
Vegetable oils are very high in omega 6 fat which is not good for horses, or humans.
