Economics of Dairy Farm: Simulation Study

Abstract

The aim of this paper is to estimate economic consequences of an LDA (Left displaced abomasum) treated cow. After a surgery to correct this displacement, cows had a lower average milk yield, lower reproduction characteristics, and consequently a lower number of lactation cycles, less calves, longer period between calving, compared to other cows. We will use breeding simulation with the help of a constructed function to describe the price aspects. Knowledge of analysis of diary milk-yield production, probability of survival, and ability to reproduce will be used. The Arena software will be used for the simulation. The main goal is to estimate the lifelong profit of an individual cow from a group of healthy cows and an individual cow from a group with LDA disease.
