Description
| - The influence of the following three factors on the relation of standardised and discounted economic weights (SDEW) for reproduction and production traits was investigated: (i) the position of breeds in the crossing system, (ii) the use of breed-sex groups for mating in different tiers and (iii) the level of the management input parameters. The SDEW for each trait was calculated as the product of the marginal economic value, the genetic standard deviation and the number of discounted expressions. The rons. The ratio of SDEW for reproduction traits to SDEW for production traits was from 3:1 to 3.7:1 which is about twice the value of the corresponding ratio of undiscounted standardized economic weights (1.7:1). In each breed-sex group, there were significant differences in the SDEWR (up to 24%) dependent on the use of this group for mating in different tiers within a given crossing system or in different crossing systems. Changes in the management parameters had only a minor impact on the SDEWR.
