Abstract: [Objectives] To make targeted breeding of new type of Shuxuan beef cattle, study and determine the breeding target traits of new type of Shuxuan beef cattle. [Methods] The difference method was used to calculate the marginal benefit of each target trait, and the economic weight of the corresponding breeding target trait was obtained. [Results] The marginal benefits of weaning weight, fattening daily gain, 18-month weight, carcass quality, dressing percentage, pure meat percentage, age at first calving, calving interval and stay group time were 35.86, 13.76, 13.05, 421.96, 375.55, 22.58, -4.45, -27.53, and 1 555.24, respectively. The relative economic weight ratio of growth traits, carcass traits, and reproductive traits was close to 4:1:5. Through marginal benefit analysis, the economic benefits obtained by improving carcass quality, dressing percentage and stay group time were significantly higher than other traits. [Conclusions] It is expected to provide a theoretic basis for establishing the target trait selection indicators for the new type of Shuxuan beef cattle.
