Effective frothy bloat prevention in a convenient block

Frothy bloat — also known as pasture or legume bloat — is the entrapment of the normal gasses of fermentation in a stable foam within the rumen. Left untreated, these gasses compress the heart and lungs and can result in death. In severe cases, death can occur in as little as half an hour from the onset of symptoms. Frothy bloat is most often associated with grazing lush, immature legume pastures (alfalfa or clover) or cereal grain pastures (wheat, oats or rye).



What is Bloat Guard®?

Bloat Guard is the only FDA-approved medicant approved for the 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, thereby releasing the gas.

Will Bloat Guard protect against different types of bloat?

No! Bloat Guard is only effective in the prevention of frothy bloat. Bloat Guard will not treat grain bloat (also known as feedlot bloat), which caused by the overeating of grain, or free gas bloat caused by a physical obstruction.

Is Bloat Guard safe?

Bloat Guard is safe for all classes of cattle, including pregnant and lactating cows and calves. There is no slaughter withdrawal for Bloat Guard. Bloat Guard is also safe for other species grazing with cattle, including horses.

How to use these blocks

Remove all other free-choice sources of salt or minerals, including white, yellow, blue or red salt blocks, as well as any loose granular salt or mineral supplements. Other sources of salt can inhibit consumption of ULTRALYX® Bloat Guard® Pressed Blocks and, thus, result in the animals not receiving enough Bloat Guard, leaving cattle susceptible to bloat. Provide AT LEAST one block per every five cattle. This allows each animal to have equal access to the blocks. Once Bloat Guard passes out of the rumen, the animal is not protected; therefore, it is vital that all cattle consume Bloat Guard on a daily basis.

Where to use these blocks

Locate blocks throughout the pasture, placing them near watering, feeding and loafing areas or other areas where animals congregate. Do not force animals to travel or search for blocks. Allow for at least 10 feet between blocks to ensure that there is equal access to each block.

When to use these blocks

Because frothy bloat can literally kill overnight, it is best to stock up on ULTRALYX Bloat Guard Pressed Blocks before lush pasture conditions develop.
