Daryl Olsen and AMVC grew from a local veterinary practice into a large swine-production business by responding to what changing farms needed. As consolidation left fewer, larger and more specialized producer clients, the Audubon Veterinary Clinic expanded beyond traditional veterinary work into contract management services. Olsen described the resulting model as providing independent producers with system-level health, production and nutrition support while letting them remain independent.
From a South Dakota livestock farm to an Iowa veterinary clinic
Olsen grew up on a livestock farm in South Dakota, earned his undergraduate degree from South Dakota State University and received his veterinary degree from Iowa State University’s College of Veterinary Medicine in 1982. He joined the Audubon Veterinary Clinic after graduating. Iowa State’s 2015 alumni profile later described the business pressure reshaping practices like Audubon’s: during the 1990s, consolidation reduced the number of traditional local producer clients, while the farms that remained grew larger and more specialized. The clinic adapted by expanding into services its clients were asking for. (Iowa State alumni profile)
An earlier encounter helped shape Olsen’s view of the veterinarian-client relationship. In a 2017 profile by Betsy Freese, Olsen recalled that in 1987 a farmer asked the young veterinarian for advice about saving his farm. Olsen said the experience showed him how much trust clients placed in veterinarians—and the responsibility that came with it. (Successful Farming profile, hosted by AMVC)
How the clinic moved into swine management
The sources give two dates for AMVC’s entry into management services. AMVC’s company history says management began in 1993 with a two-barn finishing site for 2,000 pigs. Freese’s 2017 profile says AMVC Management Services started in 1994, after clients asked Olsen whether the practice would oversee a sow unit under contract production. The dates may mark an initial site and a later formal service or company start, but the accounts do not explicitly reconcile them. (AMVC history; 2017 profile)

The shift was a response to producer needs, not simply a decision to become larger. Olsen described AMVC’s approach as providing health, production and nutrition oversight to independent producers, while allowing them to retain their independence. In the 2017 profile, he stressed that the relationship depended on transparency: explaining what the company could and could not do, and building trust over time. He also described arrangements that could let producers put their labor, equipment and land to work, including land for manure. These were Olsen’s account of the model; they do not establish that every producer arrangement was identical.
Growth measured in farms, sows and states
AMVC’s reported scale has grown since the 2017 profile, but the figures come from different dates and should not be treated as directly interchangeable rankings or audited counts.
| Source and date | Reported scale | What the figure means |
|---|---|---|
| Successful Farming profile, 2017 | 117,500 sows in seven states | The profile described sows owned or managed by AMVC. It also reported a plan to add 12,500 sows in 2018; that was a forecast, not confirmation that the addition occurred. |
| AMVC award announcement, 2022 | 23 veterinarians, 750 employees, operations in 15 states | A dated company snapshot, not current headcount or footprint. |
| AMVC About Us page, accessed October 8, 2026 | 161,500 sows across 45 farms in 11 states | AMVC’s current company-reported figures. The page calls AMVC the eighth-largest U.S. pork producer; that ranking is the company’s own description, not independently verified here. |
The 2015 Iowa State alumni profile had described AMVC as the 10th-largest U.S. pork production system. That is a historical ranking from that profile, not a current comparison. The company’s 2017 story also reported 320,000 tons of feed produced annually at that time, another historical measure of the business rather than a current figure.

Why the business was about more than adding capacity
Olsen cautioned in the 2017 profile against expanding before profitability, people and processes were in place. The story also described investment in leadership development and employee retention. His line, “Pigs are the easy part, people are what drive the business,” captured the emphasis on the workforce behind production. The profile’s point was that growth required operating capacity and capable people, not just more sows.
Rank #3
In a separate 2020 AMVC article, Olsen used the phrase “We’re just not making mistakes fast enough” to encourage veterinarians to consider new or improved practices. In context, it was a call to learn and adapt, not a claim that mistakes themselves were the goal. (AMVC article, 2020)

AMVC reported on March 3, 2022, that Olsen received the American Association of Swine Veterinarians’ Meritorious Service Award. The company described itself in that announcement as a diversified veterinary practice and swine production company operating in 15 states, with 23 veterinarians and 750 employees. Those figures belong to the 2022 announcement, not to a current staffing or operating snapshot. (AMVC award announcement)
