Using egg production longitudinal recording to study the genetic background of resilience in purebred and crossbred laying hens
There is growing interest in using genetic selection to obtain more resilient farm animals (i.e. that are minimally affected by disturbances or rapidly recover from them). The aims of this study were to: (i) e... (Source: Genetics Selection Evolution)

Using mid-infrared spectroscopy to increase GWAS power to detect QTL associated with blood urea nitrogen
Blood urea nitrogen (BUN) is an indicator trait for urinary nitrogen excretion. Measuring BUN level requires a blood sample, which limits the number of records that can be obtained. Alternatively, BUN can be p... (Source: Genetics Selection Evolution)

Predictive performances of animal models using different multibreed relationship matrices in systems with rotational crossbreeding
In livestock breeding, selection for some traits can be improved with direct selection for crossbred performance. However, genetic analyses with phenotypes from crossbred animals require methods for multibreed... (Source: Genetics Selection Evolution)

Divergent selection for natural antibodies in poultry in the presence of a major gene
Natural antibodies (NAb) are antibodies that are present in a healthy individual without requiring previous exposure to an exogenous antigen. Selection for high NAb levels might contribute to improved general ... (Source: Genetics Selection Evolution)

Effect of genotyping strategies on the sustained benefit of single-step genomic BLUP over multiple generations
Single-step genomic best linear unbiased prediction (ssGBLUP) allows the inclusion of information from genotyped and ungenotyped individuals in a single analysis. This avoids the need to genotype all candidate... (Source: Genetics Selection Evolution)

Screening for phenotypic outliers identifies an unusually low concentration of a β-lactoglobulin B protein isoform in bovine milk caused by a synonymous SNP
Milk samples from 10,641 dairy cattle were screened by a mass spectrometry method for extreme concentrations of the A or B isoforms of the whey protein, β-lactoglobulin (BLG), to identify causative genetic var... (Source: Genetics Selection Evolution)

Development of resilience indicator traits based on daily step count data for dairy cattle breeding
Resilient animals are minimally affected by disturbances, such as diseases and heat stress, and quickly recover. Daily activity data can potentially indicate resilience, because resilient animals likely keep v... (Source: Genetics Selection Evolution)
