NE-22 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 fortified, eliminating the need for additional free-choice minerals, resulting in significant cost savings.

Weather Resistant: The patented, “continuous flow” system creates a quality, low-moisture, exceptionally dense block that maintains its integrity even in hot, humid weather or precipitation.

Minimal Labor: SmartLic® NE-22 IGR is easy to feed. Simply place the blocks in areas of easy access to the cattle.

Environmentally-Friendly Packaging: Returnable steel barrels are economical and environmentally friendly and eliminate the expense of additional feeding equipment. Ask us about other available packaging options and packaging size options.

When used as directed, NE-22 IGR will provide sufficient (S)-Methoprene insect growth regulator to prevent adult horn flies emerge from the 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 0.8 ounces of NE-22 IGR per 100 lbs of animal body weight per day, which is equivalent to 8 ounces per day for a 1,000-pound animal. Provide access to fresh water and free-choice salt at all times.
