Characteristics of smallholders’ goat production systems and effect of Boer crossbreeding on body measurements of goats in Burundi

open access: yes, 2020
As part of a national action plan to manage animal genetic resources in Burundi, we characterized smallholders’ goat production systems and assessed the effect of Boer crossbreeding on animal body measures.

Dynamics of the biodiversity of black and white cattle influenced by cross-breeding

open access: yesВавиловский журнал генетики и селекции, 2015
The inter-breed crossing (crossbreeding) permits one to introduce new alleles, extend genetic diversity, and achieve desired phenotypic characteristics of initial breeds. On the other hand, crossbreeding may cause a decrease in genetic differentiation of

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 ...

Crossbreeding East African Highland Bananas: Lessons Learnt Relevant to the Botany of the Crop After 21 Years of Genetic Enhancement

open access: yesFrontiers in Plant Science, 2019
East African highland bananas (EAHB) were regarded as sterile. Their screening for female fertility with “Calcutta 4” as male parent revealed that 37 EAHB were fertile.

Different beef breed sires used for crossbreeding with Swedish dairy cows - effects on calving performance and carcass traits

open access: yes, 2020
Improved potential for weight gain and carcass classification traits in calves aimed at slaughter from dairy herds would increase the calves’ economic value, and enable an increased beef production.

Effect of crossbreeding on egg quality, incubation, and hatching activities of the pure and reciprocal cross between the Sasso and Wassache chickens.

open access: yesPoultry Science
Understanding the effect of crossbreeding on egg quality and incubation is essential for the selection of superior genetic combinations in breeding programs. This study evaluated the effect of crossbreeding on egg quality and incubation activities of the

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.
