• Identification of new genes and quantitative trait locis associated with growth curve parameters in F2 chicken population using genome‐wide association study

    Summary
    The markers which are correlated with the growth curve parameters help in understanding the characteristics of individual growth during the rearing of livestock. This study aimed to identify a set of biomarkers through a GWAS for growth curve parameters in crossbred chickens using the Illumnia 60K chicken SNP Beadchip. Growth data were collected from a total of 301 birds from cross of a broiler line and native chickens. Using the Gompertz-Laird model, two growth curve parameters, the instantaneous growth rate per day and the coefficient of relative growth or maturing index , were...

  • A genome‐wide association study for the number of teats in European rabbits identifies several candidate genes affecting this trait

    10 days ago - By Animal Genetics

    Summary
    In the European rabbit , a polytocous livestock species, the number of teats indirectly impacts the doe reproduction efficiency and, in turn, the sustainable production of rabbit meat. In this study, we carried out a genome‐wide association study for the total number of teats in 247 Italian White does included in the Italian White rabbit breed selection program, by applying a selective genotyping approach. Does had either 8 or 10 teats. All rabbits were genotyped with the Affymetrix Axiom OrcunSNP Array. Genomic data from the two extreme groups of rabbits were also analysed with...
