全球杜洛克猪亚种群和其他猪品种的基因组多样性及群体结构分析
Hui Wen,Harvey D Blackburn,Henrique A Mulim et al.
Hui Wen et al.
Background: Duroc is one of the most popular terminal sire pig breeds worldwide due to its greater growth rate, meat quality, feed efficiency, and carcass characteristics compared to other breeds. Despite the breed's popu...
Normalized cumulative gain as an alternative evaluation measure for genomic selection models [0.03%]
用于基因组选择模型的评估测度的改进方法
Felix Heinrich,Thomas M Lange,Faisal Ramzan et al.
Felix Heinrich et al.
Background: Genomic selection relies on a variety of statistical and machine learning methods to predict phenotypes from genomic data. Since no single method consistently outperforms others across datasets, evaluating and...

从虹彩凤鳚养殖中推导出育种目标和预期选择反应以减少环境影响
Simon Pouil,Joël Aubin,Florence Phocas
Simon Pouil
Background: With growing societal concerns about the sustainability of food production systems, there is increasing interest in considering not only economic gains but also environmental issues in breeding programs of far...
Comparison between repeatability, reproductive stage stratified repeatability, and relative risk models for prediction of breeding values for functional survival in rotationally crossbred sows [0.03%]
关于功能存活轮回杂交母猪育种值预测的重复性、繁殖阶段分层重复性和相对风险模型比较研究
Bjarke G Poulsen,Daniela Lourenco,Tage Ostersen et al.
Bjarke G Poulsen et al.
Background: The aim of this study was to compare different statistical models for predicting breeding values for sow survival with right-censored phenotypes from rotationally crossbred and commercial sows. We tested two h...
Genetics of digital phenotypes of keel bone in layer chickens and correlations with keel bone fractures and deviations [0.03%]
关于蛋鸡喙骨数字表型的遗传学以及与喙骨骨折和偏移的相关性研究
Moh Sallam,Lina Göransson,Anne Larsen et al.
Moh Sallam et al.
Background: Poultry is a global industry with laying hens that are genetically optimized for high egg yield. Keel bone fractures can affect up to 80% of laying hens, posing welfare and production problems. Therefore, gene...
Interfacing mechanistic and breeding scheme simulation to predict selection response on lactation efficiency in dairy cows under different nutritional environments [0.03%]
结合机制模拟和育种方案模拟预测不同营养条件对乳牛泌乳效率选择进展的影响
A Bouquet,M Slagboom,J R Thomasen et al.
A Bouquet et al.
Background: Predicting selection response for lactation efficiency in dairy cows is challenging, as the expression of this complex trait depends on dynamic interactions between the ability of cows to acquire nutrients and...
Integrative analysis of genome and transcriptome reveals a novel regulator for pork intramuscular fat content [0.03%]
基因组和转录组的整合分析发现一个新的调控因子影响猪肉肌内脂肪含量
Xueyan Zhao,Jingxuan Li,Wanli Jia et al.
Xueyan Zhao et al.
Background: Pork is a primary source of animal protein worldwide, and intramuscular fat (IMF) content is a key determinant of meat quality and consumer preference. To identify genetic regulators of IMF content, we leverag...
Unraveling the role of bacteria with heritable versus non-heritable relative abundance in the gut on boar semen quality [0.03%]
可遗传和不可遗传的大肠菌群在公猪精子品质中的作用研究
Liangliang Guo,Xiaoqi Pei,Jiajian Tan et al.
Liangliang Guo et al.
Background: The relative abundance of some bacteria in the gut of pigs is heritable, suggesting that host genetics may recursively influence boar semen quality by affecting the composition and function of gut microbiota. ...
