Development of breeding objectives for dairy cattle: Determination of economic value

The purpose of this article was to review the development of breeding objective in dairy cattle and the derivation of economic values. Breeding objective is described by a profit function that takes genetic values as input and produces profit as outcome. This profit may be a bio-economic model of the farm. The modeling methods to derive economic weights can be divided into simulation and profit functions. Cumulative discounted expressions should be multiplied by the economic value to give the discounted economic value. Key words: Dairy cattle, breeding objective, economic value
