Add a handful or two of Thunderbrook Healthy Herbal Chaff or Muesli to provide texture and aid chewing. Dampen before feeding. If feeding at the maximum amount, split between two feeds per day.
Feed alongside ad lib forage. Provide plenty of fresh water and access to a salt lick as Base Mix does not contain added salt (average horse at maintenance requires approx. 20g per day). Always introduce a new feed slowly. Add just one pinch of Base Mix to your horse’s first feed and work up gradually over four or five days to the full amount (see below).
