Characterisation of the immunomodulatory properties of spermatozoa from high and low field fertility bulls

Donnellan, Eimear (University of Limerick, 2021)

Despite passing all microscopy based quality control (QC) assessments at artificial insemination (AI) centres, bulls with apparently normal semen quality yield unacceptably low pregnancy rates. Based on a statistical ...
Comprehensive functional analysis reveals that acrosome integrity and viability are key variables distinguishing artificial insemination bulls of varying fertility

Bernecic, Naomi C.; Donnellan, Eimear; O'Callaghan, Elena; Kupisiewicz, Kasia; O'Meara, Ciara M.; Weldon, Kaitlyn; Lonergan, Patrick; Kenny, David A.; Fair, Seán (Elsevier, 2021)
