BLAD Bovine Leukocyte Adhesion Deficiency (BLF = Not carrier, BLC = Single carrier, BLS = Double carrier) BLAD is an autosomal Read more (BLF = Not carrier, BLC = Single carrier, BLS = Double carrier) BLAD is an autosomal recessively inherited defect in the Holstein population. It is characterized by recurrent bacterial infections, delayed wound healing and stunted growth. Calves with BLAD are more susceptible to infections and their lifespan varies, many die shortly after birth. Osborndale Ivanhoe (US 1189870) has been identified as the key ancestor of the disorder. Several widely used sires after Osborndale, eg. Penstate Ivanhoe Star (US 1441440) and Carlin-M Ivanhoe Bell (US 1667366) are carriers of BLAD. https://omia.org/OMIA000595/9913/ BLF Free
