In their analysis of 768 Dutch dairy cows using 153 microsatellite markers, Coppieters et al. [11] documented that FEC was associated with the QTL between 22.96 and 25.23 Mb on BTA19 and concluded that the gene located in this region, ITGAE, was involved in the immune response to parasitic diseases. The gene discussed is ITGAE; the disease is parasitic infectious disease.
