Evidence suggests that excessive non-esterified fatty acid (NEFA) production during postpartum negative energy balance (NEB) increases the risk of uterine infection. The aims of our study were to investigate associations between circulating NEFAs and uterine gene expression in postpartum dairy cows with NEB using microarray and bioinformatics techniques. Mild NEB (n=6) and severe NEB (n=6) in 12 cows were produced using different milking and...

Introduction: Infection with non-cytopathic BVDV (ncpBVDV) is associated with uterine disease and infertility in dairy cows although the underlying mechanisms are poorly understood. This project investigated the influence of ncpBVDV on innate immunity of the bovine endometrium.Materials and methods: Primary bovine endometrial cells from each of six cows were divided into four groups (Control; LPS; BVDV; BVDV LPS). Cells were infected with ncpBVDV for 4 d...
