High in digestible energy and will add calories to the diet without extra bulk.

  • McCauley's All-Natural Rice Bran Oil is excellent for improving the body condition of horses, especially those that are unable or unwilling to consume more feed.
  • One gallon of rice bran oil is equivalent to the oil content of approximately 36 lbs. of rice bran.

Natural antioxidants, notably various forms of vitamin E and gamma-oryzanols, are present in significant levels.

  • The antioxidant property of vitamin E helps to maintain cell membrane structure, red blood cell stability and capillary blood vessel integrity. Furthermore, the more active the cell (e.g., muscle cells), the greater the risk of tissue damage if vitamin E is limited. Consequently, vitamin E helps prevent muscle damage, inflammation and "tying-up" in horses. Another important function of vitamin E is its role in maximizing the immune function.

Besides having an antioxidative function, gamma-oryzanol is listed in The Merck Index (12th ed., 1996) as an anti-ulcerative. Therefore, McCauley's All-Natural Rice Bran Oil may also reduce the incidence or severity of gastric ulcers.

McCauley's All-Natural Rice Bran Oil contains approximately 2% gamma-oryzanol. Therefore, 2.5 fluid oz. (2.28 oz. by weight) will contain 1,290 milligrams of gamma-oryzanol, which is higher than the daily dose of most equine "bodybuilding" supplements.

Safe alternative for horses refusing to consume other vegetable oils.

Provides the benefits without most of the disadvantages of rice bran.

  • Less bulky
  • More palatable than rice bran
  • McCauley's® All-Natural Rice Bran Oil produces no digestive disturbances, while rice bran can occasionally cause digestive upset in horses.
  • Avoids imbalances of other nutrients. Rice bran oil contains negligible amounts of calcium and phosphorus. Rice bran, on the other hand, can contain either a high level of phosphorus and little calcium or high phosphorus and very high calcium depending on the manufacturer. The amounts of phosphorus and calcium in rice bran have the potential to significantly alter the calcium/phosphorus balance in the total diet.

Safe for hyperkalemic periodic paralysis disease (HYPP) horses, McCauley's All-Natural Rice Bran Oil contains very little potassium. Therefore, it provides an excellent source of additional calories to HYPP horse diets. Some feedstuffs commonly fed for extra calories, such as rice bran and whole soybeans, also contain high levels of potassium and would not be recommended for HYPP horses.


Directions for Use

McCauley's All Natural Rice Bran Oil should be top-dressed or mixed with feed. As a rule of good feeding practices, Rice Bran Oil should be introduced gradually. The amounts are for an average size riding horse (1,200 lb. body weight). The actual amount should be adjusted according to the body weight of the horse.

For skin & coat condition: Feed 2–4 oz. per day.

For weight gain: Feed 4–8 oz. per day. (as with any oil, feeding too much may result in loose stools.)

To ensure freshness, we recommend McCauley's All Natural Rice Bran Oil be consumed within 60 days after opening.

SHAKE WELL BEFORE USING: some of the natural components, such as lecithins and gamma oryzanol have a tendency to settle. Shaking will easily remix all of the components.

Cautions and Warnings

Shake well before using.
