Pro-Bac 4 with Reveal ATS Cattle Vaccine vaccine line was developed specifically for stocker and feeder cattle and offers the most complete protection against five of the most common BRD-causing bacteria:

  • Mannheimia haemolytica Type A1 (MhA1)
  • Mannheimia haemolytica Type A6 (MhA6)
  • Pasteurella multocida (Pm)
  • Histophilus somni / Haemophilus somnus (Hs)
  • Salmonella typhimurium (St)

Key Features:


    Our antigens are grown in specific conditions to maximize expression of all virulence factors, which optimizes post-injection antigen presentation in order to elicit a stronger immune response to better protect your cattle against the bacterial challenges they may face later on whether that is on the ranch or in the feedlot.


    Available in both 50-dose and 100-dose bottles, PRO-BAC vaccines come ready-to-use requiring no chute-side mixing and are administered in a BQA-friendly 2.0 mL subcutaneous (SQ) dose in the side of the neck.


    Choose the right antigen combination to plug into your current vaccination protocol to fill the gaps other vaccines aren't covering to set your calves up to perform on the ranch and in the feedlot.


    Our unique manufacturing process and proprietary adjuvant system (Reveal ATS™) results in vaccines that provide a high level of protection against the costliest BRD-causing bacteria without the harsh side effects often associated with the vaccination of mid- to high-risk cattle.


This product has been shown to be effective for the vaccination of healthy cattle three months of age or older against Mannheimia Haemolytica Type A-1, Mannheimia Haemolytica Type A-6 Pasteurella Multocida Type A-3. Duration of immunity has not been determined. For more information regarding efficacy and safety data, see product
