Product Application

MinLic® IGR supplement is specially formulated to enrich the diet  with essential minerals and sufficient (S)-Methoprene insect growth regulator to prevent the emergence of adult horn flies from manure of treated cattle without the added cost of supplemental protein. This unique supplement is second  to none when compared to other low moisture blocks. This block is the product of a state-of-the art patented process that provides a unique 24-hour feeding system. MinLic® IGR is an exceptionally dense block that will give you the most for your money.

Here’s how:

  • MinLic® IGR supplement is fortified with Altosid® which offers the most effective and convenient way to control horn flies in beef and dairy cattle.
  • Economical: A low feeding rate means lower feeding costs (on a per head per day basis).
  • High Mineral Fortification: This supplement is mineral and vitamin fortified which means that additional minerals do not need to be added to the diet, resulting in significant cost savings.
  • Weather Resistant: The patented, “continuous flow” system creates a low-moisture, exceptionally dense block that maintains its integrity even in hot, humid weather or precipitation.
  • Minimal Labor: The Feed In A Drum supplements are easy to feed. Simply place the block in areas of easy access to cattle.
  • Returnable Steel Tubs are self contained supplement feeders that are environmentally friendly and eliminate the expense of additional feeding equipment.

Effective Fly Control

MinLic® IGR supplement already helps improve forage utilization and reproductive performance by providing cattle the essential nutrients they need. Now MinLic® IGR will help keep horn fly populations under control too. As an insect growth regulator, Altosid  passes through cattle and into the manure. This is where the breaking of the fly cycle begins. Female flies can lay eggs in fresh manure. Within a week or so the eggs develop into larvae, then pupae and then adult flies.  The active ingredient in Altosid, Methoprene, ultimately prevents fly eggs from completing this cycle, keeping adult flies from emerging.

Kansas State University research completed in 2005 shows that feeding The  Feed In A Drum IGR supplements fortified with Altosid to cattle significantly decreases the survival rate of horn flies to the adult stage.

Magnesium Added

MinLic® IGR offers the benefit of added magnesium in a highly palatable supplement that cattle will readily consume. This supplement contains a minimum of 2% magnesium. Magnesium is needed for activation of enzymes, nerve transmission, skeletal tissue, bone formation and milk production.

Feeding Directions

When used as directed, MinLic® IGR will provide sufficient (S)-Methoprene insect growth regulator to prevent the emergence of adult horn flies from manure of treated cattle. Existing adult horn flies will not be affected. Start feeding before horn flies appear and continue use until cold weather marks the end of the horn fly season. Allow free choice to cattle. Cattle should consume an average of 0.4 ounces of MinLic® IGR per 100 lbs. of animal body weight per day, which is equivalent to 4 ounces per day for 1,000 pound animal.

  1. Assure cattle are not starved for nutrients prior to feeding MinLic® IGR.
  2. Offer cattle 1 block MinLic® IGR for every 15 – 25 head of cattle.
  3. Remove all other self-limiting nutritional supplements.
  4. Locate MinLic® IGR where cattle congregate (watering, loafing, shade areas).
  5. Replenish MinLic® IGR on a regular basis as needed.
  6. If intake of MinLic® IGR is below 0.4 ounces per 100 lbs. animal body weight per day, increase the number of feeding locations and/or change location(s) to areas more frequented by cattle.
  7. If intake of MinLic® IGR is above 0.4 ounces per animal body weight per day, reduce the number of feeding locations and/or change location(s) to areas less frequented by cattle.
  8. Introduction of this product after adult horn fly infestation is established will require treatment of cattle with adulticides if elimination of the adult fly populations is desired.

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