The analysis of the reproductive status of the cows indicated a high percentage of infertility (an average of 41.7%), which was unfavorable to the future reproduction process. The average percentages for recently inseminated cows were 22.5% and for the recently calved - 16.5%, while the percentage of pregnant cows (19.2%) was extremely unsatisfactory. The presented data showed deviations from the accepted standard indices, of a satisfactory fertility and productivity. The indices, characterizing the relative part of dystocia (16%), retention of the placenta (about 18.7%) and endometritis (about 30%), were all unsatisfactory when taking into consideration the standards set for an optimal reproduction process.
