Feeding directions:

Weight management program - feeding Purina® Equine Adult® Horse Feed at a reduced rate can help horses which are obese.  Begin by cutting the recommended feeding rate by 10%. Continue to adjust the rate until you reach the desired weight for your horse, then return to the feeding rates that are recommended for your horse's weight and activity level.

Miniature horse/ponies - Purina® Equine Adult® Horse Feed is an ideal feed for
miniature horses and ponies at maintenance and light work activity

Winter feeding - depending on your geographic location, the amount
of feed may be increased by about 10-15% to offset body heat losses.

equine adult.  The amount of equine adult can be reduced about
one pound for each 2 pounds of hay fed.
