Pfizer Animal Health's Escherichia coli (E. coli) mastitis vaccine now has a new name: ENVIRACOR J-5.

The vaccine was previously known as ESCHERICHIA COLI BACTERIN – J5 STRAIN and UPJOHN J-5 BACTERIN.

The vaccine is designed to help producers control coliform mastitis, as part of a comprehensive dry cow management approach. It includes the original E. coli J-5 strain that that is designed to help boost immunity and protect against clinical signs associated with E. coli mastitis.

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% (2 ½ 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.
  • Work with your herd veterinarian to establish best practices for proper nutrition, hygiene, cow comfort, record-keeping and culturing to enhance management efforts.

For more information about ENVIRACOR J-5 and a complete dry cow program, talk with your veterinarian or Pfizer Animal Health representative. Also, visit www.milkqualityfocus.com/drycow to learn from producers who do the best for their cows with complete dry cow care that includes ENVIRACOR J-5.
