Genetic association between different criteria to define sexual precocious heifers with growth, carcass, reproductive and feed efficiency indicator traits in Nellore cattle using genomic information
AbstractThe aim of this study was to estimate genetic parameters for different precocious calving criteria and their relationship with reproductive, growth, carcass and feed efficiency in Nellore cattle using the single ‐step genomic BLUP. The reproductive traits used were probability of precocious calving (PPC) at 24 (PPC24), 26 (PPC26), 28 (PPC28) and 30 (PPC30) months of age, stayability (STAY) and scrotal circumference at 455 days of age (SC455). Growth traits such as weights at 240 (W240) and 455 (W455) day s of age and adult weight (AW) were used. Rib eye area (REA), subcutaneous fat thickness (SFT), rump fat thic...

Bias in heritability estimates from genomic restricted maximum likelihood methods under different genotyping strategies
AbstractWe investigated the effects of different strategies for genotyping populations on variance components and heritabilities estimated with an animal model under restricted maximum likelihood (REML), genomic REML (GREML), and single ‐step GREML (ssGREML). A population with 10 generations was simulated. Animals from the last one, two or three generations were genotyped with 45,116 SNP evenly distributed on 27 chromosomes. Animals to be genotyped were chosen randomly or based on EBV. Each scenario was replicated five times. A s ingle trait was simulated with three heritability levels (low, moderate, high). Phenotypes w...

Unravelling the genetic loci for growth and carcass traits in Chinese Bamaxiang pigs based on a 1.4 million SNP array
In this study, we performed genomewide association studies (GWAS) on 43 growth and carcass traits in 315 purebred Bamaxiang pigs based on a 1.4 million SNP array. We observed considerable phenotypic variability in the growth and carcass traits in the Bamaxiang pigs. The corresponding SNP based heritability varied greatly across the 43 traits and ranged from 9.0% to 88%. Through a conditional GWAS, we identified 53 significant associations for 35 traits atp value threshold of 10−6. Among which, 26 associations on chromosome 3, 7, 14 and X passed a genomewide significance threshold of 5  × 10−8. The most remarkable l...

Joint breeding value evaluation for fertility in Finnish and Norwegian blue foxes
AbstractWe developed a multiple ‐trait animal model for blue fox fertility evaluation and estimated genetic parameters simultaneously for seven traits: first three litter sizes (LS), pregnancy rate (PREG), whelping success (WHELP), grading size (gSI) and fur quality (gQU). Grading size and quality were included into the new mult iple‐trait model as correlated traits. Litter size of the first parity had the highest unfavourable genetic correlations with gSI (−0.57) and gQU (−0.56). Thus, selection for higher gSI and gQU slows down the genetic gain in fertility traits. WHELP had moderate to fairly high negative genet...
