Description
Leigh Rosengren and co-authors present a veterinary economics study, published in 2025, on controlling a slow cattle plague called Johne's disease. The chronic gut infection quietly drains herd profit, and testing then culling carriers is the standard advice, though its payoff in beef herds was murky. The team simulated a three hundred cow western Canadian herd with an agent based model and a budget model over ten years.
Seven testing strategies, varying test type, pooled or single sampling, and testing rhythm, all cut disease spread versus doing nothing, and six made money. Yearly single animal PCR testing balanced disease control and profit best, while testing twice a year controlled most but cost more. Doing nothing let the disease grow and bled money.
