Feeding Directions

Provide free choice as a supplement to pasture cattle at the rate of one block for each 15 to 25 head. Cattle normally consume approximately 0.5 to 0.75 pounds per head daily. Consumption may vary depending on climate, grazing conditions, condition of livestock and/or availability of other feeds. In situations where climate and/or other factors result in consumption less than 0.5 pounds per head daily, intake of supplement can be increased by providing additional blocks per pasture.

Provide access to fresh water and free-choice salt at all times.

Higher Protein & Magnesium Supplements

For a higher protein The Feed in a Drum® supplement, consider Range 25.*
*Range 25 contains 25% crude protein (not more than 8% as non-protein nitrogen).

For a supplement with added magnesium and no added protein, consider The Feed in a Drum® MinLic®.

The Program

High-Mag Natural 15 w/Enzymes contains a minimum of 3% magnesium and is recommended during periods of magnesium deficiency, such as early spring growth of cool season grasses or rapid pasture growth following heavy rains. These pastures are typically low in magnesium and may result in grass tetany.


Rumen bacteria produce enzymes that digest fiber. These supplements provide additional enzymes to help aid in fiber digestion. Increased fiber digestion means cattle get more energy from the forages they consume.

A low feeding rate of 0.5 to 1 lb per head daily can significantly minimize your feeding costs on a cost per head per day basis.
