Indications

MU-SE (selenium, vitamin E) is recommended for the prevention and treatment of STD syndrome in weanling calves and breeding beef cattle. Clinical signs are: stiffness and lameness; chronic, persistent diarrhea; unthriftiness; abortions and/or weak premature calves.

Disease

• Selenium-tocopherol deficiency (White muscle disease)

Features And Benefits

• Approved for both weanling calves and breeding beef cows
• Specially formulated selenium/vitamin E combination
• Assured quantity of selenium (5mg/mL) and vitamin E (50mg/mL)

Administration

Inject subcutaneously or intramuscularly. Weanling calves: 1 mL per 200 pounds of body weight. Breeding beef cows: 1 mL per 200 pounds of body weight during the middle third of pregnancy, and 30 days before calving.

Caution: Selenium is toxic if administered in excess. A fixed dose schedule is therefore important (read package insert for each selenium-tocopherol product carefully before using).

Storage

Store between 2° and 30°C (36° and 86°F). Protect from freezing.

Precautions

Selenium-Tocopherol Deficiency (STD) syndrome produces a variety and complexity of symptoms often interfering with a proper diagnosis. Even in selenium deficient areas there are other disease conditions which produce similar clinical signs. It is imperative that all these conditions be carefully considered prior to treatment of STD syndrome. Serum selenium levels, elevated SGOT, and creatine levels may serve as aids in arriving at a diagnosis of STD, when associated with other indices.

Important: Use only the selenium-tocopherol product recommended for each species. Each formulation is designed for the species indicated to produce the maximum efficacy and safety.
