Ghorbani A., . and Mirmahdavi S. A., . and Shadparvar A., . (2004) Study on the economic weights of production traits in Iranian dairy cattle. [Proceedings Paper]
Abstract
A deterministic model were used to determine the economic weights of milk production fat percentage protein percentage and herd life based on the Iranian milk pricing system. Data from 3 dairy herds were used for model fitting and simulation. Using base conditions the economic weights of milk production fat percentage protein percentage and herd life were 745 581.5 and 790.5 460105 492630 and 161877 424857 905336 and 488234 and 506.7 -16.2 and 571.5 respectively in the three herds. Milk production fat percentage protein percentage and herd life are most sensitive to changes in average milk production milk base price and herd life. However the ration of forage to concentrate intake had the least effect on economic weights. Changes in the production factors caused differences in economic weights of traits.
