1 syringe per quarter immediately after final milking.
At the final milking of a lactation, milk the cow normally. Clean and disinfect the teats using rubbing alcohol or iodophores, or other suitable disinfectant. Infuse the contents of one syringe into each quarter by applying gentle and continuous pressure until all the suspension is expressed and leave without milking. Wear clean rubber gloves when applying. After infusion, dip each teat in an approved disinfectant teat dip.
