Horse Feeding Calculator

Calculate the correct amount of feed your horse needs based on your horse’s lifestyle and body weight.

  • Select a lifestyle and weight of horse. (Note: Weights will change based on the lifestyle selected).   
  • If little or no quality hay/pasture is available, choose from one of the complete feeds in the upper row.
  • When feeding hay, refer to daily hay requirement in the gray window, and choose from the concentrate feeds in the lower row.
lbs/day of Purina® Complete Feeds without Hay*
    lbs/day of Purina® Concentrate Feeds
      If feeding more than the suggested amount of hay or horse is grazing unlimited pasture, reduce the recommended amount of concentrate feed.

      Start with the amounts given for the weight and lifestyle of the horse.  After observing the horse for a period of time, the amount fed may be increased or decreased by 10% to obtain the desired body condition and weight.

      Feeding rates recommended for concentrate feeds are based on feeding with good quality grass hay. If using good quality alfalfa hay, reduce the amount of Purina feed recommended by 1/2 to 1 lb/day.  

      Make feed changes gradually over 7-10 days. Clean, fresh water and salt should be available at all times.

      * When feeding hay along with a complete feed, reduce amount of feed by approximately 1 lb of feed for every 2-3 lbs of hay offered. If feeding less than 0.6 lbs per 100 lbs body weight daily, then supplement ration with Enrich Plus or Free Balance 12:12 mineral.

      ** Refer to gray window for lbs/day of hay to be offered with recommended amount of feed. If feeding more than the suggested amount of hay, reduce the amount of concentrate by approximately 1 lb feed for every 2 lbs of hay above recommendation.
