    Economic Impact of Abortions in Dairy Cow Herds
    (2025) Palma, Osvaldo; Plà-Aragonès, Lluís M.; Mac Cawley Vergara, Alejandro Francisco; Albornoz Sanhueza Victor Manuel
    In this study, we address the economic impact of abortions in dairy cow herds using a cow replacement model. We employ a Markov decision model to optimize replacement decisions, considering two types of abortions that affect cow production and reproduction. Our goal was to find the best strategy to maximize the economic benefits of the herd. We found that the greatest benefit is realized when cows that are not pregnant are culled at six months of lactation, resulting in a benefit of USD 178.77 per cow per month. This model helps veterinarians and farmers make informed decisions regarding the replacement of aborted cows, thus improving efficiency and profitability in the long run. The results of this study are valuable because they help farmers manage dairy herds better, reduce costs, and increase their profits.
