Genetic evaluation for three-way crossbreeding [PDF]
Genetics Selection Evolution, 2015 Commercial pig producers generally use a terminal crossbreeding system with three breeds. Many pig breeding organisations have started to use genomic selection for which genetic evaluation is often done by applying single-step methods for which the pedigree-based additive genetic relationship matrix is replaced by a combined relationship matrix based ...

, 2020 In pig and poultry breeding programs, animals from genetically distinct purebred breeding lines are mated to produce crossbred animals, which provide food products to consumers. Although the aim of such breeding programs is to improve the performance of the crossbreds, selection takes place in the purebred lines, and is usually based on purebred ...

Estimates of crossbreeding parameters in a multibreed beef cattle crossbreeding project
South African Journal of Animal Science, 2000 Data from purebred and crossbred cattle, consisting of the Afrikaner (A), Simmentaler (S) and Hereford (H) breeds managed in a relatively intensive but high stocking rate environment, were analysed to estimate breed direct effects, individual heterotic effects, breed maternal and maternal heterotic effects for birth weight (BW) and weaning weight (WW).

Non-additive Effects in Genomic Selection
Frontiers in Genetics, 2018 In the last decade, genomic selection has become a standard in the genetic evaluation of livestock populations. However, most procedures for the implementation of genomic selection only consider the additive effects associated with SNP (Single Nucleotide
