Special Formula 17900-Forte Suspension Indications

For the treatment of acute and chronic bovine mastitis caused by susceptible strains of staphylococci, streptococci, coliforms or pseudomonads.

DOSAGE: Infuse (1) syringe (10 mL) per quarter. Repeat once after a 24 hour period if necessary.

ADMINISTRATION: Milk out udder completely. Wash udder and teats thoroughly, dry, then clean each teat end well with an enclosed alcohol swab (new one for each teat). Warm PLASTET™ disposable syringe to body temperature and shake well. Choose the desired insertion length (full or partial) and insert tip into teat canal; push plunger to dispense entire contents of the PLASTET disposable syringe and massage the quarter to distribute the medication into the milk cistern. Using a suitable teat dip, dip all teats following treatment. Do not milk for at least six hours after instillation; thereafter the animal should be milked at regular intervals and the milk discarded. Discard empty PLASTET.

Directions for the FLEXI-TUBE® System: The FLEXI-TUBE is designed to provide the choice of either insertion of the full cannula, as has traditionally been practiced, or insertion of no more than 4 mm of the cannula, as recommended by the U.S. National Mastitis Council.

a) Full Insertion: Remove the white end cap by pulling straight up as shown. Gently insert the full cannula into the teat canal; carefully infuse the product.

b) Partial Insertion: Remove both the white end cap and the red cannula by pushing sideways as shown. Gently insert the exposed white tip into the teat canal; carefully infuse the product.


Store between 15 and 25°C.
