Feeding Guidelines

CrystalBlox 30-15 supplement is designed for self-feeding to all classes of beef cattle fed low to moderate quality forages. Self-fed consumption will depend on size of animals fed, as well as quality, source and availability of other feeds, and the number of supplement containers provided.

This unique block form combines the controlled intake of a low-moisture block with the higher nutrient delivery of a compressed block. Feed at the rate of one container for every 10-40 head, with a minimum of two (2) containers in each lot or pasture to ensure proper accessibility. Mature cattle typically consume between 0.75 and 1.50 pounds per head per day, based on a 1,200 lb. animal.


NOTE: CrystalBlox Brand Supplements deliver a continuous supply of nutrients and are designed as a supplement to the animal’s diet. When quantity or quality of other feedstuff is limited, supplemental nutrients in addition to those provided by CrystalBlox Brand Supplements may be required. In situations where additional nutrients are needed, contact your feed representative for specific recommendations.

WARNING: This product, which contains added copper, should not be fed to sheep or any species that have a low tolerance to supplemental copper.

CAUTION: USE ONLY AS DIRECTED.  FOR RUMINANTS ONLY.  Consumption of selenium should not exceed 3 mg per head daily.
