Optimal pre-vacccination for BRD and feedlot induction

Pre-vaccination is the mew standard for modern beef production.

In contemporary Australian beef feedlot systems, pre-vaccination against bovine respiratory disease (BRD) before cattle even set foot in the yard is considered no longer optional, it’s vital for success.

BRD continues to be the leading cause of health and financial loss in feedlot cattle, driving up treatment costs, reducing average daily gain (ADG), and putting welfare and carcass value at risk. 1

Science-backed gains

Australian studies show pre-vaccinated, yard-weaned cattle have significantly reduced BRD rates, faster adaptation, higher ADG, and lower pulls and mortality than those merely managed at induction.

It has been estimated producers using optimal pre-feedlot strategies, including respiratory vaccination, could add millions of dollars in value to the beef sector annually. 1,2

Pre-vaccination is especially critical because most BRD morbidity strikes in the first month on feed, precisely when immune responses are weakest and management transitions are most disruptive. 1

Vaccinating before induction at the feedlot ensures that the cattle are protected during all critical stress periods, from on farm mustering, transport and induction, mixing, location and climatic changes which accumulate to become the highest-risk window for BRD.

Gold Standard: Rhinogard IBR and Bovi-Shield MH-One

Dual protection matters because BRD is a complex syndrome, not a single disease, but a cascade triggered by stress, viral infection (commonly IBR), and bacterial pathogens (especially Mannheimia haemolytica ).

Optimising pre-vaccination means targeting both the viral and bacterial elements, giving animals broad protection before they’re exposed to feedlot stressors.

Combining Rhinogard and Bovi-Shield MH-One is the highest standard:

  • Rhinogard IBR: Delivers rapid, local, and systemic immunity against Infectious Bovine Rhinotracheitis, with protection developing as quickly as 3-4 days after a simple intranasal dose3. Rhinogard IBR stops IBR disease at the site of infection. Field trials have demonstrated that cattle vaccinated with Rhinogard at induction had improved average daily weight gain and feed conversion efficiency.3
  • Bovi-Shield MH-One: Brings robust immunity against Mannheimia haemolytica (MH) validated in challenge studies with demonstrated protection against Australian strains of MH. Protection is achieved within just 7 days and lasts for at least 120 days - covering the critical induction and early feeding periods where BRD occur. Bovi-Shield MH-One is formulated to provides protection against both the MH bacteria and the potent leukotoxin it produces.

Both are single-dose vaccines, making logistics easier and ensuring maximum compliance, even in large, commercial operations. Flexible with both 10 dose and 50 dose packs which minimises wastage.

Making BRD prevention easier and profitable:

  • Single-day program: Both vaccines can be given during a single yarding, reducing time and handling costs.
  • No missed protection window: Both deliver immunity on-farm - when it counts, before stress and disease risk peak.
  • No needles (Rhinogard): Intranasal administration is stress-free, safe for all ages of cattle, and works even where maternal antibodies are present.
  • Unique technology: Amphigen adjuvant in Bovishield MH-One and both products having freeze-dried antigens and validated for Australian cattle and pathogens.
  • Now available in ONE convenient combination pack
  • Healthier, faster-adapting cattle: Fewer sick pulls, higher ADG, better feed conversion providing lower costs and higher profits.

Conclusion: The competitive edge is pre-vaccination – with the right tools

As Australian beef production evolves, the best-managed, most sought-after feeder cattle will be fully prepared before feedlot entry.

Pre-vaccination using Rhinogard and Bovi-Shield MH-One together offers field-proven rapid protection, single dose technology, and practical advantages.

Combined with yard-weaning that translate directly into financial performance, animal welfare, and supplier reputation.

Pre-vaccination is not only good medicine – it’s good business.

For the highest performing Australian feedlot cattle and the best reputation in the beef supply chain – pre-vaccination, done right, with Rhinogard and Bovi-Shield MH-One, is the clear solution.
