Lockout® (bismuth subnitrate)
Teat sealant aiding in the prevention of new intramammary infections
Lasting teat protection.
When left up to nature, a dry cow’s natural keratin plugs may not form in time – or at all – to protect them from infection. That’s why LOCKOUT teat sealant simulates these plugs at dry off, creating an antibiotic-free barrier between the udder and bacteria in the environment.
When using this teat sealant for mastitis-preventive care, we recommend following a herd approach to mastitis control. LOCKOUT teat sealant is compatible with conventional dry cow management practices and is safe for use on non-lactating dairy cows and replacement dairy heifers. It requires no milk or pre-slaughter withdrawal. If intramammary antibiotics are administered while using LOCKOUT, please follow recommended withdrawal times.
Blue paste makes it easy to distinguish LOCKOUT from milk at first milking. In addition, the teat sealant offers:
- A compact syringe that holds the same amount of product in a smaller tube. Not to mention a larger thumbpad for easier administration.
- A simple pull-off cap. No need to twist or turn the top – it pulls straight off.
- A short, half-inch plunger that makes it easy to administer a full four-gram dose of sealant into each teat.
LOCKOUT teat sealant is available in single-dose syringes, containing 4 grams of a sterile, non-antibiotic blue paste composed of 60 percent bismuth subnitrate in a mineral oil vehicle. Each syringe is sufficient for one teat.
One pail of LOCKOUT contains 144 syringes for the treatment of 36 animals.
