Inert Ingredient:

Bloat Guard Caution

Certain components of animal feeds, including medicated premixes, possess properties that may be a potential health hazard or a source of personal discomfort to certain individuals who are exposed to them. Human exposure should, therefore, be minimized by observing the general industry standards for occupational health and safety.

Precautions such as the following should be considered: dust masks or respirators and protective clothing should be worn; dust arresting equipment and adequate ventilation should be utilized; personal hygiene should be observed; wash before eating or leaving a work site; be alert for signs of allergic reactions-seek prompt medical treatment if such reactions are suspected.

Directions For Use

The dose of Bloat Guard is proportional to body weight and also depends upon the severity of the bloat-producing conditions. The dose of 1 g of poloxalene per 100 lb of body weight is recommended for cattle under moderate bloat-producing conditions. For cattle under severe bloat-producing conditions, the dose should be doubled (2 g of poloxalene per 100 lb of body weight).

Use the enclosed measure which is equal to 1/4 of a standard measuring cup and holds approximately 2/3 oz of Bloat Guard by weight. Each 2/3 oz by weight contains 10 g of poloxalene (the active drug ingredient).

Bloat Guard is to be consumed daily. Bloat Guard should be sprinkled on individual rations of ground feed, starting 2 or 3 days before animals are exposed to bloat-producing conditions.

Repeat the feeding of Bloat Guard when animals are exposed to bloat-producing conditions for more than 12 hours from the last feeding of Bloat Guard, but do not exceed the higher dose level in any 24-hour period.

If your animals do not accept Bloat Guard readily, stir the recommended amount into their feed. After animals become accustomed to the change in diet, sprinkle Bloat Guard on top of the feed.

Bloat Guard Caution

It is essential that each animal consumes the total recommended dose of Bloat Guard daily for adequate protection.
