    This study was conducted to evaluate the effect of calcium propionate administrations on serum ßhydroxybutyrate (BHBA) concentration and subclinical ketosis occurrence in dairy cows. Twenty four multiparous Holstein cows were sorted by parity, body condition score and dry matter intake in close-up period, average milk production of previous lactation and season of calving and assigned to one of the three groups. Each group consisted of eight cows. The cows in group 1 (G1) received two drenches at calving and 24h after calving. The cows in group 2 (G2) received three drenches at calving, 24h after calving and 7 days after calving. The cows in group 3 (G3) were the control (no drench). Each drench contained 0.68kg of calcium propionate. There were no statistical differences for serum BHBA concentrations at all times among groups (P>0.05), except for the difference at calving between G1 and G3 (P<0.05). Two drenches of calcium propionate tended to decrease serum BHBA concentration and the incidence of subclinical ketosis during first 4 weeks of lactation.
