EnergiLass Rumen Booster is a supplement for stressed cattle in the feedlot or on pasture; for cows before and during the breeding season.

EnergiLass Rumen Booster is formulated for preconditioning, stressed, shipped-in feeder cattle, or cattle in sick pens on tall types of rations. Rumen Booster can also be offered to cows and heifers during the breeding season, to dairy calves at weaning and stressed dairy cows. 

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 could 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. 

Continuous Protein Delivery 

As pastures mature, forage quality can decline. Supplementing with protein allows the rumen to better digest mature forages. 

Thiamine and B Vitamins

Thiamine and B Vitamins are known to stimulate intake of cattle under stress.

 Added Salt

 Salt encourages supplement and water intake, both important in stressed calves. Also helps maintain electrolyte balance.

 Complexed trace minerals

 Complexed trace minerals to improve trace mineral availability and utilization.

 Trace minerals and vitamins 

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