    The aim of study was to evaluate the influence of using EMTM probiotics in dairy cattle feeding on production and reproductive performance and birth weight of calves. The present investigation was undertaken at a large commercial farm in West Pomerania province in 2010. 211 cows were chosen to determine the effect of EMTM probiotics on studied parameters. These cows were divided into two groups: Control Group (A) and Treatment Group (B). Group B were fed during first month of the experiment 150 ml/day/animal probiotics and in next months 75 ml/day/animal. In current work we analyzed chosen reproductive parameters (age at first calving and intercalving period) and milk performance in standard lactation. It has been noticed that cows in Group B in 1st lactation characterized higher milk yield, FCM, fat and protein yield [kg] and fat content (P ≤ 0.01) compared to Group A. In addition, during comparing both groups it was found that cows in Group B in 3rd lactation received the highest milk yield, FCM, fat and protein yield [kg]. Considering protein yield the result was significant (P ≤ 0.05). On the other hand, no significant differences were found for using EMTM probiotics on reproductive parameters and calves’ birth weight [kg].
