Abstract

Economic values for production, reproduction, growth and functional traits in crossbred and Holstein cow production systems in Guilan province were estimated using a total of 16 herds consisting in average 12 and 30 cow, respectively, and a bio-economic model. Economic values were calculated in two production systems for 12 traits, classifying into four categories of production, reproduction, growth and survival. Economic value of each trait was estimated as the amount of change in the annual profit of production system by one unit increase in mean of the considered trait while the means of other traits were hold unchanged. Economic values, relative to the economic value for productive lifetime, for milk yield, fat yield, protein yield, age at first calving, calving interval, pre-weaning daily gain, post-weaning daily gain, birth weight, mature live weight, pre-weaning survival rate and post-weaning survival rate were, respectively 3.7, 0.003, -0.01, -7.26, -32.6, -4.35, -23.4, -46.55, -0.78, 4.26 and 68.68 for crossbred production system, and were 0.92, 0.001, -0.002, -6.72, -20.64, -1.10, -6.10, -11.82, 0.21, 30.49 and 25.29, for Holstein production system. The results showed, although the importance of some traits in two production systems were different, which was a reflection of overall difference in two production systems, the breeding objective of two population should be very close together, considering high similarity of economic values of traits.
