Genetic distinctness of African, Asian and South American local chickens.
The genetic variability of various local chicken populations derived from Bolivia, India, Nigeria and Tanzania was evaluated with 22 microsatellites and showed high levels of heterozygosity with the lowest value of 45% for the population named Aseel from India and the highest value of 67% for Arusha from Tanzania.

A genome scan reveals QTL for growth, fatness, leanness and meat quality in a Duroc-Pietrain resource population.
A genome-wide QTL scan for production traits in a line cross between Duroc and Pietrain breeds of pigs, which included 585 F(2) progeny produced from 31 full-sib families genotyped with 106 informative microsatellites, found forty QTL exhibited additive inheritance whereas 31 QTL showed (over-) dominance effects.

QTL for microstructural and biophysical muscle properties and body composition in pigs
Microstructural properties of pig muscle and meat quality are governed by genetic variation at many loci distributed throughout the genome and QTL analysis under both, the line-cross and half-sib model, allows detecting QTL in case of fixation or segregation of the QTL alleles among the founder populations and thus provides comprehensive insight into the genetic variation of the traits under investigation.

Trait correlated expression combined with expression QTL analysis reveals biological pathways and candidate genes affecting water holding capacity of muscle
The complex relationships between biological processes taking place in live skeletal muscle and meat quality are driven by the energy reserves and their utilisation in the muscle and on the other hand by the muscle structure itself and calcium signalling. Expand
Relationship between myosin heavy chain isoform expression and muscling in several diverse pig breeds.
The study demonstrates that My HC IIb fibers are the most prominent in pigs having large LM area and implies that MyHC IIb is the determining fiber contributing to the differentiation of large and small loin eye muscle area in the pig. Expand
Identification of genes differentially expressed during prenatal development of skeletal muscle in two pig breeds differing in muscularity
BackgroundPostnatal muscle growth is largely depending on the number and size of muscle fibers. The number of myofibers and to a large extent their metabolic and contractile properties, which alsoExpand
Molecular genetic analysis of porcine mannose‐binding lectin genes, MBL1 and MBL2, and their association with complement activity
The study promotes the porcine MBL genes as functional and positional candidate gene for complement activity and identifies a quantitative trait locus for C3c serum level close to the position of the MBL gene. Expand
Bovine NALP5, NALP8, and NALP9 Genes: Assignment to a QTL Region and the Expression in Adult Tissues, Oocytes, and Preimplantation Embryos
Assignment to a QTL region for reproductive traits and preferential expression of NALP9, NalP8, and NALp5 in oocyte, germinal lineage, and gonad cells may suggest their functional relevance to reproduction and possible contribution to phenotypic variation. Expand
QTL for the heritable inverted teat defect in pigs
The results confirm the previously proposed polygenic inheritance of the inverted teat defect and, for the first time, point to genomic regions harboring relevant genes. Expand
The effect of nitric oxide inhibition and temporal expression patterns of the mRNA and protein products of nitric oxide synthase genes during in vitro development of bovine pre-implantation embryos.
Data provide the first evidence for the role of NO production and the presence of mRNA and protein products of NOS isoforms during bovine embryogenesis. Expand
