Merck Animal Health this week launched a new teat sealant product called ShutOut. Designed for use prior to drying cows off, the product is intended to aid in the prevention of intramammary infections.
“Given the environmental and physiological changes they experience at dry-off, cows are at an elevated risk for developing mastitis,” Brian Miller, D.V.M., ruminant technical services veterinarian, Merck Animal Health said in a press release. “Pathogen risk is greater, partly due to variability in keratin plug formation, a cow’s natural defense against new intramammary infections during the dry period.”
The need for teat sealants during dry-off is well documented. The National Mastitis Council’s (NMC) Recommended Mastitis Control Program recommends using a teat sealant when dry cows are exposed to high levels of environmental pathogens.
ShutOut is a sterile, antibiotic-free barrier designed for ease of use to meet the needs of today’s dairy operations, the release said adding a short plunger stroke, dual-tip option and an easy-to-break cap, means producers can efficiently treat their cows at dry-off.
“Producers can rest easy knowing when ShutOut is administered, it’ll effectively seal the cow’s teats,” Miller said. “ShutOut provides a trusted, physical barrier to prevent environmental organisms from entering the udder.”
Each syringe of ShutOut consists of 4.0 grams of a sterile, antibiotic-free, intramammary paste containing 2.6 grams of bismuth subnitrate, Merck said.
Like all teat sealants, the material must be stripped from quarters following freshening and before first milking, said Miller.The label calls for stripping each quarter 10 to 12 times before the unit is attached.
