Feeding Directions

Provide free choice as a supplement to pasture cattle, and horses at the rate of one block for each 15 to 25 head and to sheep or goats at a rate of one block for each 25 to 35 head. Place in pasture near areas frequented by livestock, such as watering locations, shade or loafing areas. Cattle typically consume 0.5 to 1.0 pound per head daily. Sheep normally consume approximately 3 to 4 ounces per head per day. Mature horses will typically consume 1 to 3 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 expected, intake of supplement can be increased by providing additional blocks per pasture.

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