Genetic evaluation for three-way crossbreeding [PDF]

open access: yesGenetics 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 ...

Influence of inbreeding and crossbreeding on the in vitro embryo development during normal and heat stress condition [PDF]

open access: yesمجله بیوتکنولوژی کشاورزی, 2012
Inbreeding and Heat stress have negative effects on reproductive performance of dairy cattle. Two suggested strategies to overcome to these factors are to use crossbreeding and crossbreeding with thermo tolerant genotype, respectively.

Genetics of crossbreeding

open access: yes, 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 ...
