ShutOut®

Active Ingredient
BISMUTH SUBNITRATE 650 mg/g.

Description and Pack Sizes:
Bismuth subnitrate 2.6g in an oily base in a 4 gram syringe. Available in tubs of 144 syringes.

Indications
For the prevention of mastitis during the non-lactating (dry) period: 

• In lactating heifers (first calvers) and cows with somatic cell counts (SCC) of less than 120,000 and 150,000 respectively.
• In cows and heifers with a higher somatic cell count (SCC) immediately following treatment with appropriate antibiotic dry cow therapy. 

SHUTOUT is also indicated for the prevention of peri-calving mastitis in maiden heifers.

Dosage
Infuse the entire contents of one SHUTOUT syringe to form a seal.  After infusion do not massage or squeeze the teat, as this may dislodge the seal.
Lactating heifers and cows with SCC below 120,000 and 150,000 respectively:
Immediately after the last milking at drying off, prior to treatment with SHUTOUT, the udder should be stripped. The recommended method is to disinfect and treat one teat at a time. Clean teat thoroughly with a teat wipe (or cotton wool ball) moistened in 70% methylated spirits (30% water) until no longer visibly dirty.  Teats should be allowed to dry prior to insertion. Carefully infuse the entire contents of one syringe to form a seal. Repeat the process on the other three teats and finish by teat spraying all teats. After infusion do not massage or squeeze the teat, as this may dislodge the seal.

Teats should be allowed to dry prior to insertion.  Insert appropriate antibiotic dry cow therapy CEPRAVIN DRY COW (A003322) or CEFASAFE (A007158) and massage into the quarter as per the respective product label. Re-disinfect the teat. Carefully infuse the entire contents of one SHUTOUT syringe to form a seal. Repeat the process on the other three teats and finish by teat spraying all teats. After infusion do not massage or squeeze the teat, as this may dislodge the seal.
