# What happened
# Who is doing what JBS introduced a pre-entry vaccination requirement in its NSW feedlots and has expanded the practice. Five years after first mandating vaccination in its three NSW yards, JBS now reports 100 percent of Angus cattle in all five of its Queensland and New South Wales yards are pre-vaccinated using Coopers Bovilis MH+IBR. Other large operators accept vaccinations using Zoetis Bovishield as well as Coopers Bovilis MH.
# Measured industry outcomes MLA's Feedlot R&D Program Manager, Dr Tony Batterham, presented industry-level results: while the number of cattle on feed has grown by about 50 percent over the last decade, BRD mortality has fallen by roughly 50 percent. That means mortality has declined even as throughput increased.
Dr Batterham attributed the change to improved immune responses driven by vaccination and the value of vaccinating all susceptible cattle in a yard. When vaccination is structural — built into entry requirements — he said the results are more consistent. If pens contain a mixture of vaccinated and unvaccinated animals, the benefits are less certain.
# Operational effects on feedlot teams Speakers stressed practical benefits beyond mortality statistics. Fewer BRD cases means pen riders pull and treat fewer animals, reducing labour pressure and allowing staff to focus on other health issues or management tasks. JBS's livestock leadership and Gundamain both reported that fewer cattle present with respiratory signs, which eases strain on infrastructure and teams and reduces the number of chronic animals that leave the feedlot underperforming or as rejects.
# What worked in practice
- Mandated pre-entry vaccination: JBS' policy has driven near-universal coverage for certain breeds in its yards.
- Revaccination in-yard: Gundamain's day-13 revaccination protocol addressed gaps where incoming cattle were not pre-vaccinated and suited their high-mix intake.
- Accepted vaccine products: both Coopers Bovilis MH+IBR and Zoetis Bovishield were in use across operators.
# Practical takeaway for producers and lotfeeders If the goal is to reduce BRD-related deaths and chronic cases, make vaccination policy consistent across the cohort of susceptible cattle in a pen or yard. Where pre-vaccination at source is not universal, plan a reliable in-yard revaccination or recheck schedule. Consistent coverage aligns immune responses across pens, which appears linked to the reduced morbidity and mortality reported at BeefEx 2026.
