Abstract

The aim of the study is to optimize the feed balance of dairy cows. For this purpose, an optimization
model based on linear programming is applied. In order to establish the most balanced nutrition of the
cows on the farm, the production structure is optimized. A case from a farm operating in the Sofia
region is presented. The optimization model has been successfully adapted to the management of an
agricultural enterprise, with the criteria for optimal gross margin and profit. The solution of the task
optimizes the feed balance of the dairy cows and optimizes the production structure of the farm.
