Feeding Instructions

CAUTION: USE AS DIRECTED. Consumption of selenium should not exceed 3 mg per head daily.

This pesticide product is to be used as a cattle feed-through pesticide for the control of horn flies. All feed ingredients listed on this product label must adhere to the specifications and limits (if applicable) ascribed by the Food and Drug Administration (FDA) for cattle feed use when mixed with this pesticide product. This product contains ethoxyquin, a preservative. The amount of ethoxyquin may vary according to the individual manufacturer’s formulation and will not exceed the 150 ppm maximum limit established for ethoxyquin by FDA, per 21 CFR 573.380.

WARNING: This product, which contains added copper, should not be fed to sheep or any species with a low tolerance to supplemental copper.

Introductory Period: Following a 7 to 10 day acclimation period, average consumption should be 1 to 2 pounds per head per day for mature cattle with unrestricted forage supplies. Position the blocks 50 to 75 feet from loafing, feeding and watering areas. Some re-positioning of blocks may be necessary as cattle become acclimated to the presence of the blocks. Move blocks closer to increase consumption; further away to decrease consumption. If over consumption occurs for more than two weeks and re-positioning of blocks does not correct the situation, remove blocks and evaluate the overall feeding program. DO NOT ALLOW STARVED ANIMALS FREE ACCESS TO THIS BLOCK.

Feed this product to cattle only. When used as directed, Sweetlix EnProAl 16% with Altosid® 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 34 mg of (s)-methoprene per 100 lbs of cattle body weight per month to achieve horn fly control. This is equivalent to an average of 1.6 ounces of this product per 100 lbs of cattle body weight per day, which is equivalent to 1 pound (16 ounces) per day for a 1000-lb. cow.
To open: Remove protective cover.

  1. Assure cattle are not starved for nutrients prior to feeding Sweetlix EnProAl 16% with Altosid®.
  2. This product contains added copper. Do not feed to cattle in close proximity to sheep or other species that have a low tolerance to supplemental copper.

  4. Offer cattle one Sweetlix EnProAl 16% with Altosid® for every 15 to 25 head of cattle.
  5. Locate Sweetlix EnProAl 16% with Altosid® where cattle congregate (watering, loafing, shade areas).
  6. Replenish Sweetlix EnProAl 16% with Altosid® on a regular basis as needed.
  7. If intake of Sweetlix EnProAl 16% with Altosid® is below 1.6 oz. per 100 lbs. cattle body weight per day, increase the number of feeding locations and/or change locations to areas more frequented by cattle.
  8. If intake of Sweetlix EnProAl 16% with Altosid® is above 1.6 oz. per 100 lbs. cattle body weight per day, reduce the number of feeding locations and/or change locations to areas less frequented by cattle.
  9. Introduction of this product after adult horn fly infestation is established will require treatment of cattle with adulticides if elimination of the adult fly population is desired.
