Administration: A­fter last milking at dry-off or prior to the first lactation in replacement dairy heifers, thoroughly clean and disinfect teat ends with alcohol swabs provided and leave to air dry. Do not use water with or without disinfectant. If a dry cow antibiotic has been infused, teat should be re-swabbed with alcohol swab provided prior to infusion. A clean, disinfected, and dry teat is essential. Infuse teats in the opposite order to cleansing. Insert tip of a new syringe into teat canal. To minimize product from entering the udder, squeeze the top of teat canal at the base of the udder. Gently depress plunger until teat canal is full. Remove and discard syringe. Treat remaining teats in a similar fashion, using a new syringe for each teat. Do not massage teats or udder following infusion of LOCKOUT.
Removal: Do not remove LOCKOUT by the action of a milking machine. The blue color aids in identifying the product at the time of removal to reduce the potential for accumulation in milking equipment. Thoroughly hand-strip every teat, 10 to 12 strips per teat before milking. Dispose of any unused product or sealant stripped from an animal in accordance with federal, state, and local requirements. Bucket milk fresh cows for a minimum of three milkings per normal post-calving procedure.
Withdrawal Information: For use in dry dairy cows and replacement dairy heifers only. If accidentally administered to a lactating cow, the product can be stripped out by hand. If LOCKOUT is administered following an antibiotic infusion, the withdrawal periods for meat and milk for the antibiotic must be observed. LOCKOUT has a zero-day milk and meat withdrawal when used alone.
