Development and use of a simulated cattle population for teaching animal breeding. 3. Results with regard to practical cattle breeding



Development and use of a simulated cattle population for teaching animal breeding. 3. Results with regard to practical cattle breeding



Z. Tierzucht. ZuchtBiol, 87: 42-55



Analysis of simulated data on a dairy population gave the following results. Changes in genetic herd means over 2 yr were influenced 66.8% by the selection of bulls in the population, 13.3% by selection of bulls for individual herds and 4.6% by selection of dams within herds. Where breeding values were estimated from performance measured as deviations from herd or population averages, genetic progress tended to distort results by increasing the corresponding means.
