Exploiting within‐breed variability in the autochthonous Reggiana breed identified several candidate genes affecting pigmentation‐related traits, stature and udder defects in cattle

2 monthes ago   |   By Animal Genetics

Summary
Autochthonous cattle breeds constitute important reservoirs of genetic diversity. Reggiana is an Italian local cattle breed reared in the north of Italy for the production of a mono-breed Parmigiano-Reggiano cheese. Reggiana cattle usually have a classical solid red coat colour and pale muzzle. As part of the strategies designed for the sustainable conservation of this genetic resource, we investigated at the genome-wise level the within-breed detected variability of three pigmentation-related traits (intensity of red coat colour, based on three classes - light/diluted, normal and...

A further survey of the quantitative trait loci affecting swine body size and carcass traits in five related pig populations

2 monthes ago   |   By Animal Genetics

Summary
Breeding for good meat quality performance while maintaining large body size and desirable carcass traits has been the major challenge for modern swine selective breeding. To address this goal, in the present work we studied five related populations produced by two commercial breeds and two Chinese breeds. A single-trait GWAS performed on 20 body size and carcass traits using a self-developed China Chip-1 porcine SNP50K BeadChip identified 11 genome-wide significant QTL on nine chromosomes and 22 suggestive QTL on 15 chromosomes. For the 11 genome-wide significant QTL, eight were...
