The aim of this study was to evaluate hematological and blood biochemical changes, in association with urinalysis and physical examination of dairy cows in puerperium as well as to verify the efficiency of protocols capable of monitoring the onset of metabolic and infectious diseases. The study was conducted using 22 Holstein cows, 11 primiparous and 11 multiparous, aged from two until seven years, belonging to the dairy herd of the Teaching, Research and Extension in Dairy Cattle Unit - UEPE/GL, of the Department of Animal Science of the Federal University of Viçosa. A total of 154 blood and urine samples were analyzed. The research consisted of clinical monitoring along with laboratory analysis (blood count, blood biochemistry and urinalysis). The following methodology was established in order to measure clinical variables along with blood and urine samples: fifteen days before calving (T-15), immediately after calving (T0), two days (T2), five days (T5), ten days (T10), fifteen days (T15) and thirty days after calving (T30). During physical examination a gradual loss of body condition score and postpartum infections were verified; leukocytosis with neutrophilia and lymphocytosis immediately after calving were also observed through blood count; blood biochemistry showed elevated levels of urea, hyperphosphatemia and hypochloremia during the transition period; urinalysis showed low values of urine pH shortly before calving. These results confirmed the efficiency of clinical and laboratory monitoring in the diagnosis of metabolic diseases in dairy cows during the puerperium period and the monitoring protocol used was accurate.
