Haematological and biochemical analyses of blood as well as bacteriological investigations of uterine lumen and milk were performed for 38 dairy cows in the first and fourth week after parturition. Clinical examination demonstrated that general health of all cows was satisfactory, but laboratory analysis showed serious deviance from the norm. Cows with pathological performance of uterine involution had higher body temperature and total white blood cell count than the cows with physiological performance of uterine involution (p is less than 0.05). In all investigated cows, the content of total protein, albumin, Ca, P and Mg in blood serum was lower than the norm (p is less than 0.01), but the level of LDH was elevated (p is less than 0.01). Bacteriological contamination of uterus was observed in 44.4% of cows in the first week after parturition, but in the fourth week – in 31.4% of cows. No microflora in the cow's milk was detected in 11.1% of cows in the first week after parturition, but in the fourth week – in 31.5% of cows. A positive correlation was found among anaerobic microflora of uterine lumen and milk (r=0.31, p is less than 0.05). Microbiological examination showed no significant differences among cows with physiological and pathological uterine involution. The research suggests that biochemical analysis of blood can be used to evaluate cow's metabolic processes and provision of nutrients but not as a prognostic parameter for post-parturition pathologies. Deficiency of Ca, P, Mg and protein seems to be one of reasons why the cow's organism is not capable of eliminating microbial contamination from the reproductive system in the post-parturition period.
