Genetic analysis of pathogen-specific intramammary infections in dairy cows
Saranya G. Narayana,Saranya G. Narayana,Flavio S Schenkel,Filippo Miglior,T.C.S. Chud,E.A. Abdalla,S. Ali Naqvi,F. Malchiodi,Herman W. Barkema +8 more
TL;DR: Assessment of genetic variation of overall and pathogen-specific IMI in nonclinical primiparous and multiparous cows using bacterial culture indicated that long-term direct genetic selection for pathogen
Evidence of post-natal transmission of Neospora caninum in Dutch dairy herds
TL;DR: Findings strongly indicate a post-natal infection of the animals in the high seroprevalence age-groups, probably due to a point source exposure to N. caninum.
Integrated Comparative Transcriptome and circRNA-lncRNA-miRNA-mRNA ceRNA Regulatory Network Analyses Identify Molecular Mechanisms Associated with Intramuscular Fat Content in Beef Cattle
Vahid Dehghanian Reyhan,Farzad Ghafouri,Mostafa Sadeghi,S. R. Miraei-Ashtiani,John P. Kastelic,Herman W. Barkema,Masoud Shirali +6 more
TL;DR: This study identified the primary metabolic-signaling pathways associated with IMF and fat metabolism, including calcium, cGMP-PKG, thyroid hormone, oxytocin signaling, and other metabolic pathways, which could inform marker-assisted selection and identify regulatory molecular mechanismsassociated with IMF in beef cattle.
Integrated transcriptome and regulatory network analyses identify candidate genes and pathways modulating ewe fertility
Vahid Dehghanian Reyhan,Mostafa Sadeghi,S. R. Miraei-Ashtiani,Farzad Ghafouri,John P. Kastelic,Herman W. Barkema +5 more
TL;DR: In this paper , the authors explored the genetic basis of ewe fertility by combining RNA-Seq data analyses of ovarian tissues from high and low fertility ewes with published transcriptome studies.
