MADISON, N.J. — Producers and veterinarians vaccinating with the Pfizer Animal Health Escherichia coli
) mastitis vaccine as part of a comprehensive dry cow management approach will now call it by a new name: Enviracor J-5. Previously known as E. Coli
Bacterin – J5 Strain and Upjohn J-5 Bacterin, the pioneer E. coli
mastitis vaccine remains the same trusted and efficacious product to help lessen severity of E. coli
"The E. coli mastitis vaccine from Pfizer Animal Health has always given producers the control to help manage coliform mastitis," says Bradley Mills, senior veterinarian, Pfizer Animal Health Cattle Technical Services. "Enviracor J-5 continues to provide the same efficacy and level of confidence you’ve trusted for years but with a new name and package."
Enviracor J-5 includes the original E. coli J-5 strain that helps boost immunity and protect against clinical signs associated with E. coli mastitis. Enviracor J-5 is now available in 100 mL and 250 mL vials.
In conjunction with the name change, Pfizer Animal Health also conducted a new study in which pregnant cows were vaccinated with Enviracor J-5 according to label directions and compared with negative controls following an E. coli challenge.
The study found:
- Enviracor J-5 vaccinates experienced a 41% (2½ days) shorter duration of E. coli mastitis, translating to more salable milk, when compared with control cows.
- Vaccinates experienced a 50% reduction in E. coli environmental shedding, helping control the spread of this environmental pathogen.
Mills advises producers to work with their veterinarian to set up a comprehensive dry cow program that treats subclinical mastitis infections with Spectramast DC (ceftiofur hydrochloride) Sterile Suspension, keeps out new infections with an internal teat sealant such as ORBESEAL and vaccinates against E. coli mastitis with Enviracor J-5.
"When incorporated into dry cow care, research shows Enviracor J-5 can provide up to an additional $57 profit per cow per lactation, making an estimated $5 investment in a three-dose Enviracor J-5 vaccination protocol well worth it," Mills adds. "Investing in a complete management approach equips cows with a triple-strength defense against environmental pathogens, preparing them for better milk quality and higher returns in the next lactation."
Mills also urges producers to work with their herd veterinarian to establish best practices for proper nutrition, hygiene, cow comfort, record keeping and culturing to enhance management efforts.
