Feeding Directions

It is a violation of Federal law to use this product in a manner inconsistent with its labeling. 1. Feed 1 block per 5 head of cattle or horses to allow all animals equal access. Feed blocks at the rate of 0.88 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. Animals will consume about 8.8 oz. per head daily based on a 1000- lb animal. 4. Blocks can be fed to animals in confinement. Exact locations of blocks to obtain desired consumption will vary between confinement feeding programs.
5. Feed as the only FREE CHOICE source of salt, other minerals and vitamins.  VMS® EnProAl® Fly Control Block with Rabon® prevents the development of fecal flies in the manure of treated cattle and horses, but it is not effective against existing adult flies.
6. 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 also in other decaying matter on the premises. In order to achieve optimum fly control, use in conjunction with other good management and sanitation practices.
7. Start feeding VMS® EnProAl® Fly Control Block with Rabon® early in the spring before flies begin to appear and continue feeding throughout the summer and into the fall. This block may be fed to cattle up to slaughter.
8. Follow feeding directions. Consumption of selenium should not exceed 3 mg per head daily.
