ISBN: 978-84-615-0062-8http://hdl.handle.net/10532/2019Pregnancy and peripartum period are characterised by transient changes in the maternal immune system, noticeable at the peripheral level. The aim of the study was to determinate the effect of placental retention and metritis on peripheral white blood cells in 91 pregnant dairy cows from day 200 of pregnancy to 30 postpartum. Blood samples were automatically analysed with HemaVet® Multispecies Haematology system and total and differential leukocyte counts were recorded. Data was statistically analysed using GLM repeated measures ANOVA to test the effect of reproductive disorders on peripheral white blood cells. Cows with placental retention had significantly lower leukocyte, neutrophil and lymphocyte counts (P<0.05), and cows with metritis had lower neutrophil and eosinophil counts (P<0.01) than cows not suffering reproductive disorders during the peripartum period. Day of pregnancy and parturition also affected peripheral lymphocyte and monocyte counts (P<0.01).
