Setegn Worku Alemu,Timothy P Bilton,Patricia L Johnson et al.
Setegn Worku Alemu et al.
Background: Methane emissions from ruminant livestock pose a significant challenge to mitigating climate change. Genomic selection offers a promising approach to reduce methane emissions, but prediction accuracy remains l...
Positive selection on rare variants of IGF1R and BRD4 underlying the cold adaptation of wild boar [0.03%]
IGF1R和BRD4罕见变异的正向选择与野猪寒冷适应性进化相关研究
Jianhai Chen,Ivan Jakovlić,Mikhail Sablin et al.
Jianhai Chen et al.
Background: Domestic piglets often die of hypothermia, whereas Eurasian wild boar (Sus scrofa) thrives from tropical lowlands to subarctic forests. The thermoregulation of wild boar offers a natural experiment to uncover ...
The impact of deregressed foreign breeding values on national beef cattle single-step genomic evaluation [0.03%]
国外育种值去回归对全国肉牛单步基因组评估影响的研究
Damilola Adekale,Zengting Liu,Ross Evans et al.
Damilola Adekale et al.
Background: In recent years, genetic evaluations in cattle breeding have shifted from purely national evaluations to multinational evaluations considering relatives from other countries. Integrating international estimate...
Genetic parameters and potential of reducing tail and ear damage in pigs through breeding [0.03%]
猪遗传参数及通过育种减少尾咬伤和耳咬伤的潜力
Bernadett Hegedűs,Natália Galoro Leite,J Elizabeth Bolhuis et al.
Bernadett Hegedűs et al.
Background: Ear and tail biting are behaviours in pigs that cause both welfare problems and financial losses. Data collection of behaviour is difficult at the large scale needed for breeding. The damage inflicted on victi...
Estimating the genetic parameters of resilience toward known and unknown disturbances in sheep using wool fibre diameter and body weight variability [0.03%]
基于纤维直径和体重表型变异估计羊群对已知和未知逆境胁迫的适应性遗传参数
Erin G Smith,Samuel F Walkom,Dominic L Waters et al.
Erin G Smith et al.
Background: General resilience in animals can be quantified by analysing the variability in longitudinal data. However, it is unclear whether resilience indicators derived from different longitudinal data series can predi...
Accurate determination of breed origin of alleles in a simulated smallholder crossbred dairy cattle population [0.03%]
在一个模拟的小型奶牛养殖杂交群体中精确确定等位基因的品种来源
Berihu Welderufael,Isidore Houaga,R Chris Gaynor et al.
Berihu Welderufael et al.
Background: Accurate assignment of breed origin of alleles (BOA) at a heterozygote locus may help to introduce a resilient or adaptive haplotype in crossbreeding. In this study, we developed and tested a method to assign ...
Bivariate GWAS performed on rabbits divergently selected for intramuscular fat content reveals pleiotropic genomic regions and genes related to meat and carcass quality traits [0.03%]
