Crossbreeding parameters for carcass traits of broiler rabbits
The carcass traits of broiler rabbits HYPLUS were analyzed. The weight least squares means were used for estimating crossbreeding effects. The model of Dickerson was used to estimate of additive effect, heterosis and recombination loss. Hete...

Selection of the terminal sire and dam breeds of sheep and its impact in commercial crossbreeding
Four variants of selection programme in combination with crossbreeding system of sheep were simulated. Crossbreeding is more efficient then purebreeding. Selection goal (and selection indices) depends on position of the breed in

Analysis of gene action in growth traits of Hereford x Czech Pied cattle
Means and standard errors of pre- and postweaning growth traits of Hereford and Czech Pied cattle and their crossbreds F1, B1, B11 and B111 were used for the estimation of of the crossbreeding parameters : - mean, direct and materna...

Crossbreeding of farm animals with aplication to beef cattle
The starting models for crossbreeding are genetic and population models, which describe the genetic structure of pure- and crossbred populations. Genetic effects were divided into population and heterosis effects with regard to the direct, m...

Principles of beef cattle breeding
The main ways of genetic improving of beef cattle performance traits were analysed. The genetic variability within breeds (breeding value estimation, selection and crossbreeding) only a marginal attention was paid. The genetic variability be...
