Abstract

The main purpose of this study is to estimate the relative emphasis on production and reproductive traits in dairy herds of Pars Livestock Company. This study was conducted using a bioeconomic model and by determining the economic value or genetic growth rate of production and reproductive traits and determining the relative importance of each of these traits in breeding programs of dairy cattle breeding system of Pars Livestock Company in Ardabil province. The first step in the development of breeding goals is to determine the economic coefficients for the traits that are considered as breeding goals. The economic value of a trait indicates the contribution of the genetic growth of a trait in improving the economic efficiency of the production system. In order to study the effects of change in input values on the model response, sensitivity test was used. Also, for comparing different attributes, the relative emphasis of each attribute was calculated. The annual profit of each productive cattle in this research was reported to be 195529076 Rials. Attributes can be divided into several categories in terms of the type of effects on revenues and expenses.
