With the purpose of diagnosing the presence of possible causes of reproductive losses, 4 groups of breeding females were surveyed and formed after the mated period ended in 5 beef cow-calf ranches (BCR) of Salta province. The groups in each BCR were: PC, pregnant cows (n=15), PH, pregnant heifers (n=15), NPC, no pregnant cows (n=10) and NPH, no pregnant heifers (n=10). At pregnancy diagnosis, body condition (BC) was recorded and females were sampled for diagnosis of brucellosis, bovine viral diarrhea virus (BVD), bovine herpesvirus 1, infectious bovine rhinotracheitis (IBR), neosporosis and leptospirosis. Blood Se values and serum Cu, Zn, Mg, Ca and thyroxine (T4) were determined. In the 5 BCRs, a greater (p
