25 lb. blockSafe-Guard (fenbendazole) En-Pro-Al Molasses Deworming Supplement Block (Medicated) is designed for deworming pastured cattle by feeding these medicated blocks for three days only as the sole source of salt.

For the removal and control of:

  • Lungworms
  • Stomach worms (adults and fourth stage larvae)
  • Brown stomach worm
  • Intestinal worms (adults and fourth stage larvae)
  • Hookworm
  • Thread-necked intestinal worm
  • Small intestinal worms
  • Bankrupt worm

Adequate forage must be available at all times to cattle receiving supplemental block feeding.

It is essential to establish full cattle adaptation to supplemental block feeding prior to treating cattle with Safe-Guard En-Pro-AL Molasses Deworming Block (Medicated). Cattle behavior and per capita consumption must be established by feeding non-medicated En-Pro-AL Blocks prior to medicated block treatment. Adaption to block feed intake for medicated treatment may take 12 to 19 days prior exposure to unmedicated feed blocks depending on consumption rates and environmental conditions. When cattle block consumption of 0.1 pound (1.6 oz) per 100 pounds of body weight (or 1.0 lb. for mature cattle) per day is attained for several days on the nonmedicated En-Pro-AL Block, the three day medicated treatment with Safe-Guard En-Pro-AL Molasses Deworming Supplement Blocks (Medicated) may begin.


1.67mg fenbendazole per kg body weight per day for three days. Total dose for the three day period of 5mg fenbendazole per kg of body weight (2.27mg fenbendazole per pound).

Under conditions of continued exposure to parasites, retreatment may be needed after six to eight weeks.
