In this study, the relationship between milk production and the factors used in milk production have been analyzed and the cost of milk production has been calculated. The data used for this study has been acquired from 94 dairy cattle breeder enterprises by the face to face survey method. It has been determined that the forage and concentrated feed costs compose 57% of the total production costs and 71% of the variable costs. It has been also determined that the dairy cattle breeding production division of the costs belong to 20.99% of productive stock value (PSA), 76.31% of milk production and 2.7% of manure production and 1 kg milk cost has been calculated as 0.29$. Additionally, according to the path analysis, it has been found out that the 61.49% variation resulting from the milk production can be explained with the changes resulting in the use of forage and concentrated feed. Through the path analysis, the direct and indirect effects of the feed materials used on the milk production have been analyzed. As a result, it has been found that silage maize (20%) and barley(14%) have the biggest effect on the milk yield.
