Economic Evaluation of Breeding Objectives for Milk and Beef Production in Temperate Zones

چکیده
Intensive milk and beef production is COIlIIlPn to the European agricultural due to a high density of population. Milk and beef traits are involved in breeding objectives of dual-purpose cattle. Various dual-purpose cattle populations cover a wide range of economic ting of milk and beef. The optimal weights of milk and beef characters on the marginal change in profit, and the time and nUIlber of .. " genetic inprovement of the traits. OVerproduction prevails in the and especially in the EEC sub markets of beef, milk and grain. The equilibrimn IOOdel of Linear Progranuning can be used to reliably evaluate the economic weights of dairy and beef traits. In the work from ADELHELM et al. (1972), HENZE et al. (1980) and ZEDDIES four sets of economic weights are derived for milk and beef traits, based distinct economic situations in the FoRoG.. Then the influence of the economic weighting on the breeding objective, and the genetic ill'l:lrOVF!l1lF!I'1It-and beef is detronstrated on the breeding plan of a German dual-purpose population.

Milk and Beef Production in Temperate Climates
Milk production in the temperate climates accounts for 66% of the world milk output. In North America only about 20% of beef originates from dairy herds, while in Europe beef production is a by-product of dairying. Several studies showed small genetic correlations between milk and beef traits, thus suggesting the possibility of simultaneous selection for both .characteristics. European breeding...
