Producers and veterinarians vaccinating with the Pfizer Animal Health Escherichia coli (E. 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 ESCHERICHIA COLI BACTERIN – J5 STRAIN and UPJOHN J-5 BACTERIN, the E. coli mastitis vaccine remains the same product, which is purported to lessen the severity of E. coli mastitis.

“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,” says Bradley Mills, senior veterinarian, Pfizer Animal Health cattle technical services.

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 percent (2 ½ days) shorter duration of E. coli mastitis when compared with control cows.
  • Vaccinates experienced a 50 percent reduction in E. coli environmental shedding, helping control the spread of this environmental pathogen.

“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.

Mills 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. PD
