Alfa A Oil to 2 of the horses which goes with their Spillers Slow Release cubes and my yearling just gets a tiny handful of Happy Hoof with his balancer. Their feeds are always fed well damped down as well.
The reason i feed Alfa A Oil is for weight gain for my TB.
I can't get it any cheaper than £14.10 as we only have 3 feedstores in the area so i suppose they can charge what they want & all 3 are priced the same.
