Death loss caused by acute bloat can be significant, even sub-acute cases of frothy bloat are costly to cattle producers.  Frothy bloat (also known as pasture or legume bloat) is most often associated with ruminants grazing lush, immature, legume pastures (alfalfa or clover) or cereal grain pastures (wheat, oats or rye).  Additionally, ruminants inconsistently consuming dry alfalfa hay and/or aggressive consumption of small particle sized grains may also be susceptible.

Gas in frothy bloat becomes trapped in foam, preventing the animal from eructating (belching) excess gas.  Therefore, it is necessary to introduce an antifoaming agent into the rumen.  Poloxalene (Bloat Guard®) is the only FDA-approved medicant approved for prevention of frothy bloat in cattle. Bloat Guard®reduces the surface tension in the walls of the bubbles so that they can combine with other bubbles and burst, thus releasing the gas.



1. To be fed at the rate of 0.8 oz. of block per 100 lb. of body weight per day. Example: 8 oz. (0.5 lb.) of block for a 1000 lb. animal daily.

2. For adequate protection it is essential that each animal consume the total recommended dosage of SWEETLIX®Bloat Guard®Block Daily.

3. Omit all salt from feed. Do not feed free choice sources of salt or mineral containing salt in any form. These blocks are an adequate source of salt.

4. Begin feeding blocks continuously. Feed blocks and full feed dry non-legume hay at least 48 hours prior to legume (alfalfa, clover) consumption. Repeat when block consumption is interrupted to maintain control.

5. Provide at least 1 block for each 5 head of cattle; add 1 additional block when each block has been half-consumed.

6. The location of the block is extremely important for adequate consumption. Place blocks where cattle congregate (watering, grazing and loafing areas) in order to limit the distance an animal must travel to have ready access to a block.

7. Controlled grazing practices (Strip Grazing) are recommended in order to limit the distance an animal must travel to have ready access to a block.

8. In some instances, it may be necessary to confine cattle in a dry lot with additional SWEETLIX® Bloat Guard® Blocks for a period each day.

Prevention of legume (alfalfa, clover) and wheat pasture bloat when fed continuously during exposure to bloat-producing conditions. 


USE AS DIRECTED.Consumption of selenium should not exceed 3 mg per head daily.  Access to, and intake of blocks may be limited during or directly after heavy rain or dew, and after frost or change of pasture.  Variation in cattle routine may change their feeding and watering habits.  Relocate blocks immediately as necessary.  Special caution should be taken.  Water high in salt and alkaline soils limit consumption and performance.
