Economic values in cattle breeding. II. Influences of production circumstances in situations with output limitations

Abstract

This study discusses sensitivity of economic values of milk and beef production traits in cattle breeding to imposition of limitations at the farm level and to production circumstances in situations with limitations. Economic values are calculated in situations without limitations, with milk output limitations, with roughage input limitations and with simple product output limitations. The imposition of milk output limitations results in a decrease in economic value of carrier (milk without fat and protein). The imposition of roughage input limitations mainly causes a decrease in economic values of beef production traits relative to the economic values of milk production traits. Simple product output limitations strongly influence relative economic values of production traits. In situations with limitations, economic values are sensitive to product and production-factor prices, milk production level and level of mature weight.
