I bought this to create a bit of interest for my ‘fatty’ horse who has minimal hard feed but was throwing it about as it was mainly boring chaff. He now eats every scrap and licks the bowl. It smells great and I feed it to all of my horses for the added vits and minerals. They all look very well and all enjoy their feeds.

Excellent tonic to add to any feed for condition.

Oakley has suffered with outbreaks of hives since I bought him a year ago. One thing we noticed was they came up as a stress reaction. Brewers yeast was suggested so I tried as a last attempt before referring to vet for tests. 3months on and now no hives =happy owner!
