Theoretical aspects of crossbreeding [PDF]
Genetics Selection Evolution, 1971 SUMMARY Methods of utilising breeds and bleed crosses in animal production are discussed, taking account of both genetical and economic aspects. The theoretical principles for breed and breed cross comparison are analysed, but most emphasis is given to methods of improvement of existing crosses.

Characterization of Autozygosity in Pigs in Three-Way Crossbreeding
Frontiers in Genetics, 2021 Crossbreeding in livestock can be used to increase genetic diversity. The resulting increase in variability is related to the heterozygosity of the crossbred animal. The evolution of diversity during crossbreeding can be assessed using genomic data.

Smallholder experiences with dairy cattle crossbreeding in the tropics: from introduction to impact
Animal, 2015 Crossbreeding of indigenous tropical and improved western dairy cattle breeds as tool to improve dairy cattle performance on smallholder farms has been widely advocated, criticised and yet applied. The government of Ethiopia supported this technology for

Economics of Swine Crossbreeding Systems [PDF]
Journal of Agricultural and Applied Economics, 1979 Crossbreeding in commercial hog operations is widely practiced and has increased substantially in recent years. Perhaps the most important positive feature of crossbreeding is heterosis, i.e., the performance of crossbred progeny is superior to the average performance of the parents.

Crossbreeding in Random Forest
CoRR, 2021 Ensemble learning methods are designed to benefit from multiple learning algorithms for better predictive performance. The tradeoff of this improved performance is slower speed and larger size of ensemble learning systems compared to single learning systems.

Breed of origin of alleles and genomic predictions for crossbred dairy cows
Genetics Selection Evolution, 2021 Background In dairy cattle, genomic selection has been implemented successfully for purebred populations, but, to date, genomic estimated breeding values (GEBV) for crossbred cows are rarely available, although they are valuable for rotational ...
