Abstract: Analysis of acidified feed components containing African swine fever virus

Mitigation of African swine fever (ASF) virus in contaminated feed materials would assist control activities. Various finely-ground pig feed ingredients (5 cereals, 4 plant proteins, 2 animal proteins, 1 oil, 1 compound) were sprayed and mixed thoroughly with a buffered formic acid formulation (0, 1 or 2% vol/vol) to produce a consistent and durable level of formate (1% or 2%) with consistent acidification of cereal ingredients to less than pH 4. No such acidification was noted in other ingredients. Selected representative feed ingredients were further mixed with infectious ASF virus (106 TCID50) or media alone and incubated for 0, 6, 12, 24, 48, 72 or 168 h. The residual ASF virus at each timepoint was quantified using qPCR and a cell culture based TCID50 assay to determine survivability. Maize, rice bran and compound feed (with or without formate) all reduced infectious ASF virus to levels below the detection threshold of the cell culture assay (101.3 TCID50/mL). A consistent reduction in ASF virus DNA levels was observed by qPCR assay when maize containing ASF virus was mixed with 1% or 2% buffered formic acid.

Video: CEOs of the Industry: Dr. Jay Miller, The Maschhoffs

CEOs of the Industry, we sit down with Dr. Jay Miller, CEO of The Maschhoffs, to explore his remarkable journey from veterinary consultant to executive leader at one of America’s largest family-owned pork production companies.

Dr. Miller shares how his outside-in perspective shaped his leadership approach, what it was like transitioning from advisor to CEO, and how he’s balancing the company’s proud multigenerational legacy with the need for transformation and innovation.

We dig into tough topics like navigating company contraction, reshaping culture for performance, and the critical role veterinary expertise plays at the executive level. Dr. Miller opens up about building a sustainable, modern pork business—not just environmentally, but operationally and culturally—and what it takes to attract and develop the next generation of talent in agriculture.

Looking ahead, he shares his five-year vision for The Maschhoffs and gives us a personal peek in the Fast Five round, where he reveals leadership insights, the best advice he’s received, and the three words that define The Maschhoffs in 2025.
