Feeding Recommendations: 

  1. Feed 1 block per 5 head of cattle or horses. This allows all animals equal access to blocks. Feed blocks at the rate of 0.5 oz. per 100 lb. of bodyweight per day. This intake will supply 0.07 g of larvicide per 100 lb. of bodyweight per day (2.1 grams per 100 lbs. bodyweight per month). 
  2. Place blocks where animals congregate. Locate blocks throughout pasture, placing them near water and loafing areas. Maintain adequate distance between blocks (10 ft. minimum). 
  3. Do not allow animals to run out of blocks. When a block is half-consumed, provide a new block near it. Place very small pieces in troughs or feed pans.
  4. Animals will consume approximately 5 oz. per head daily. When animals consume the block at the recommended rate, it will supply 3 mg of selenium. 
  5. Blocks can be fed to animals in confinement. Exact location of blocks to obtain desired consumption will vary between confinement feeding programs. 
  6. Feed as the only FREE CHOICE source of salt, and other minerals and vitamins.
  7. SWEETLIX®Rabon® Molasses Pressed Block  prevents the development of fecal flies in the manure of treated cattle and horses, but it is not effective against existing adult flies. It may be necessary to use other control measures to reduce the population of existing adult flies. Supplemental fly control measures may be needed in and around buildings to control adult house flies and stable flies which breed not only in animal manure but also in other decaying matter on the premises. In order to achieve optimum fly control,  SWEETLIX®Rabon® Molasses Pressed Block  should be used in conjunction with other good management and sanitation practices. Start feeding  SWEETLIX®Rabon® Molasses Pressed Block  early in the spring before flies begin to appear and continue feeding throughout the summer and into the fall.  SWEETLIX®Rabon® Molasses Pressed Block  may be fed to cattle up to slaughter. 
  8. Follow feeding directions. Consumption of selenium should not exceed 3 mg per head daily.
