An economic simulation was carried out over 183 milk-producing countries to estimate the global impacts of 12 dairy cattle diseases and health conditions: mastitis (subclinical clinical), lameness, paratuberculosis (Johne's disease), displaced abomasum, dystocia, metritis, milk fever, ovarian cysts, retained placenta, ketosis clinical). Estimates disease on yield, fertility, culling were collected from literature, standardized, meta-analyzed using a variety methods ranging simple averaging random-effects models, adjusted for comorbidities prevent overestimation. These comorbidity-adjusted then combined with set country-level lactational incidence and/or prevalence estimates, herd characteristics, price estimates within series Monte Carlo simulations that estimated valued losses due these diseases. It total annual are USD 65 billion (B). Subclinical ketosis, clinical mastitis, subclinical costliest modeled, resulting in mean approximately 18B, 13B, 9B, respectively. Estimated paratuberculosis, placenta be 0.2B, 0.6B, 6B, 5B, 4B, 3B, Without adjustment comorbidities, when statistical associations between disregarded, aggregate would have been overestimated by 45%. Although greatest India (USD 12B), USA 8B), China 5B), depending measure used (losses as percent GDP, per capita, gross revenue), relative burden across varied markedly.
