Is it really necessary to give a third shot of UPJOHN J-5 BACTERIN (Escherichia Coli Bacterin J-5 Strain) after freshening?
If you ignore giving the third shot of UPJOHN J-5 BACTERIN at freshening, you are putting your fresh cows at more risk of exposure to coliform mastitis early in lactation. One shot of UPJOHN J-5 BACTERIN at dry-off provides 10 percent protection against coliform mastitis. A second shot 30 days later gives 30 to 40 percent protection. Adding the third recommended shot after freshening provides 60 to 80 percent protection against coliform mastitis – twice the efficacy of competing products. This increased efficacy means that the three-shot regimen pays off, even when as few as one percent of quarters in a herd are infected. An economic analysis by University of California-Davis shows that you can gain $32 to $57 net profit per cow per lactation by using UPJOHN J-5 BACTERIN according to recommendations.
