J-Vac (Killed E. Coli) is a highly effective and reliable vaccination for healthy cows and heifers, offering crucial protection against detrimental effects caused by Escherichia coli (E. coli) and Salmonella typhimurium infections. This unique core antigen vaccine is approved with a dual claim, making it the go-to choice for preventing mastitis caused by E. coli, as well as helping prevent the effects of endotoxemia.

One of the standout features of J-Vac is its powerful formula, containing the J-5 mutant E. coli Bacterin-Toxoid. This potent combination ensures optimal prevention against E. coli infections and salmonellosis, safeguarding the health and well-being of your livestock.

With J-Vac, there is no need for milk withholding, providing you with convenience and peace of mind. Additionally, this vaccine offers a 21-day slaughter withdrawal period, ensuring consumer safety and compliance.

What sets J-Vac apart is its versatility and suitability for use in pregnant and lactating dairy cows. It is a safe and reliable choice for protecting the health of both the cows and their offspring.

Administering J-Vac is a breeze. Prior to use, simply shake the vaccine well. For mastitis prevention, administer a single 2 mL dose intramuscularly or subcutaneously either at 7 months of gestation or at the time of dry off. For optimal effectiveness, revaccination should occur 1 to 3 weeks before calving, and yearly thereafter.

To prevent the effects of endotoxemia, whole herd vaccination can be performed at any time. Administer a 2 mL dose as the initial vaccination, followed by a second 2 mL dose 2 to 4 weeks later. It is crucial to revaccinate annually for continued protection.

For calves under 6 months of age, it is recommended to revaccinate after reaching 6 months of age to ensure sustained immunity.
