Spatial modelling improves genomic evaluation in Tanzanian smallholder admixed dairy cattle
BACKGROUND: Smallholder dairy production systems in low-and middle-income countries are characterised by large phenotypic variance due to diverse environmental effects, …
Article scientifique
Investigating the footprint of post-domestication dispersal on the diversity of modern European, African and Asian goats
Abstract Background Goats were domesticated in the Fertile Crescent about 10,000 years before present (YBP) and subsequently spread across Eurasia …
Article scientifique
Natural clines and human management impact the genetic structure of Algerian honey bee populations
BACKGROUND: The Algerian honey bee population is composed of two described subspecies A. m. intermissa and A. m. sahariensis, of …
Article scientifique
Optimization of alternative breeding schemes for the genetic improvement of common Tigray highland sheep in northern Ethiopia
BACKGROUND: Genetic improvement is one of the major means to enhance the productivity of livestock, and well-designed animal genetic improvement …
Article scientifique
Two approaches to account for genotype-by-environment interactions for production traits and age at first calving in South African Holstein cattle
BACKGROUND: If not accounted for, genotype x environment (G×E) interactions can decrease the accuracy of genetic evaluations and the efficiency …
Article scientifique
How have sheep breeds differentiated from each other in Morocco? Genetic structure and geographical distribution patterns
BACKGROUND: Based on the relatively homogeneous origin of the sheep breeds in Morocco that originate mainly from Iberia, it is …

Diversity of endogenous avian leukosis virus subgroup E (ALVE) insertions in indigenous chickens
BACKGROUND: Avian leukosis virus subgroup E (ALVE) insertions are endogenous retroviruses (ERV) that are restricted to the domestic chicken and …
Article scientifique
Genetic parameters for body weight and different definitions of residual feed intake in broiler chickens
BACKGROUND: The objectives of this study were to (1) simultaneously estimate genetic parameters for BW, feed intake (FI), and body …

Genome-wide association scan for heterotic quantitative trait loci in multi-breed and crossbred beef cattle
BACKGROUND: Heterosis has been suggested to be caused by dominance effects. We performed a joint genome-wide association analysis (GWAS) using …
Article scientifique
Misidentification of runs of homozygosity islands in cattle caused by interference with copy number variation or large intermarker distances
BACKGROUND: Runs of homozygosity (ROH) islands are stretches of homozygous sequence in the genome of a large proportion of individuals …
Article scientifique
Eigen decomposition expedites longitudinal genome-wide association studies for milk production traits in Chinese Holstein
BACKGROUND: Pseudo-phenotypes, such as 305-day yields, estimated breeding values or deregressed proofs, are usually used as response variables for genome-wide …

Accuracies of univariate and multivariate genomic prediction models in African cassava
BACKGROUND: Genomic selection (GS) promises to accelerate genetic gain in plant breeding programs especially for crop species such as cassava …
Article scientifique
Genetic parameters and expected responses to selection for components of feed efficiency in a Duroc pig line
BACKGROUND: Improving feed efficiency ([Formula: see text]) is a key factor for any pig breeding company. Although this can be …
Article scientifique
Interaction of direct and social genetic effects with feeding regime in growing rabbits
BACKGROUND: Most rabbit production farms apply feed restriction at fattening because of its protective effect against digestive diseases that affect …
Article scientifique
Analysis of the genetic variation in mitochondrial DNA, Y-chromosome sequences, and MC1R sheds light on the ancestry of Nigerian indigenous pigs
BACKGROUND: The history of pig populations in Africa remains controversial due to insufficient evidence from archaeological and genetic data. Previously, …
