Sweetlix® Rabon® Block

Tag: 13406165
Form: Pellet
Weight: 50 lbs.

Sweetlix® Rabon® Block is a mineral block designed to aid in the control of fecal flies in the manure of treated cattle and horses. It also prevents the development of face flies, horn flies, house flies, and stable flies in the manure of treated cattle and the development of house flies and stable flies in the manure of treated horses.

Feed one block per five head of cattle or horses. This allows all animals equal access to blocks. Feed blocks at a rate of 0.5 oz. per 100 lb. of body weight. This intake will supply 0.07 grams of larvicide per 100 pounds of body weight per day (2.1 grams per 100 lbs. body weight per month).


Place blocks where animals congregate. Locate blocks throughout pasture, placing them near water and loafing areas. Maintain adequate distance between blocks (10 ft. minimum).


Do not allow animals to run out of blocks. When a block is half-consumed, place a new block near it. Place very small pieces in troughs or feed pans.


Cattle or horses should consume about 5 oz. per head daily. When animals consume the block at the recommended rate, it will supply 3 mg. of supplemental selenium.

Blocks can be fed to animals in confinement. The exact location of blocks to obtain desired consumption will vary between confinement feeding programs.


Feed as the only free choice source of salt, other minerals and vitamins.

Sweetlix® Rabon® Molasses Pressed Block prevents the development of fecal flies in the manure of treated cattle and horses but 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 can breed not only in animal manure but 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. Sweetlix® Rabon Molasses Pressed Blocks should not be used in horses in conjunction with other cholinesterase inhibiting compounds. Owners of debilitated, aged, breeding, pregnant or nursing horses should consult a veterinarian before use.

Follow feeding directions. Consumption of selenium should not exceed 3 mg per head per day.
