畜牧 Currently, the economic weights for traits included in the EBI are on a per lactation basis. In order, to avoid further changes in economic weightings in the EBI it is proposed to continue the definition of the EBI on a per lactation basis. This is why the CDE reported by Berry et al. (2005) are scaled down by the CDE of annual cow traits under complete market failure (i.e., 1.58) The proposed economic weights and relative emphases on traits included in the proposed EBI under two scenarios of zero market failure or complete market failure are summarised in Table 1 and 2, respectively.
