abstract = "Objective: Physiological Imbalance is a pre-clinical disease state in dairy cows that cannot be directly observed but is assumed to precede subclinical and clinical diseases in the beginning of lactation in dairy cows.

The objective of this study was to estimate the costs and benefits associated with an indicator-based intervention against Physiological Imbalance with different indicator accuracies, herd prevalences and prices.Materials and methods: We used a mechanistic, dynamic, and stochastic dairy herd model that simulates the production and state changes of dairy cows (SimHerd) to estimate the negative effects associated with the diseases that were mediated through Physiological Imbalance and developed an effect chart to quantify the cost and benefits associated with the outcome of the FT-MIR results and based on those a deterministic cost-benefit analysis.
