Product Description

EnergiLass Cattle Mineral 8 AFC is a mineral and vitamin supplement designed to be fed to beef calves and cattle consuming high quality pasture, hay or forage during the horn fly season.

Features & Benefits

High energy

Molasses and added fat results in a very high level of sugar and energy. This high sugar level and the licking action needed for consumption increase saliva production. This, in turn, may improve the rumen environment which would improve forage digestion.

Highly palatable

The high level of molasses solids and fat make for a highly palatable product. The licking action along with saliva produced softens the top 1/4 inch of the block allowing limited consumption. When this thin layer is consumed the animals must wait for the next layer of the block to soften before they can consume additional product.

Trace minerals and vitamins

Formulated to provide trace minerals and vitamins to help support optimal animal health and performance.

Altosid Fly Control

Horn flies cost the cattle industry billions each year in lost milk production, lost calf gains, and lost cow performance. An integrated fly control program, including Altosid, can keep horn fly populations at bay.
