The research took place on a farm in North-Eastern Romania with Holstein Friesian cows aged between 3 and 9 years. Bacteriological investigations were carried out throughout the year 2023, on a total of 35 cows, including 25 multiparous cows and 10 primiparous cows, 23 cows had eutocic parturitions and 12 cows had dystocic parturitions, during the first 3 weeks postpartum. In the case of dystocic parturition, biological samples yielded isolates including 9.3% strains classified as , 8.1% strains of , 4.1% strains of , and 2.3% strains of . Other bacterial types were identified in lesser proportions. In the case of eutocic parturition, was most frequently isolated: 18.6% of the isolated bacterial strains, followed by 5.8% spp., 4.6% spp., 4.6% species, 3.5% spp., and spp., and 2.3% spp. It is noted that on the 7th day of puerperium, the mean value of colony-forming units per milliliter (CFU/mL) was 74 × 10 CFU/mL in normal calving cows compared to 29 × 10 CFU/mL in cows with dystocia. The total number of recorded germs increases significantly during the first 14 days postpartum in all cases, higher levels being shown in cows with dystocic calving. For statistical analysis, the independent t-test ( < 0.05) was made by using the SPSS 16 software. The object of the research is the bacteriological load in Holstein Friesian cows depending on the type of eutocic parturition/dystocia.
这项研究在罗马尼亚东北部的一个农场进行，研究对象是3至9岁的荷斯坦奶牛。2023年全年对总共35头奶牛进行了细菌学调查，其中包括25头经产奶牛和10头初产奶牛，在产后的前3周内，23头奶牛顺产，12头奶牛难产。在难产的情况下，生物样本分离出的菌株包括9.3%的 菌株、8.1%的 菌株、4.1%的 菌株和2.3%的 菌株。其他细菌类型的比例较低。在顺产的情况下，最常分离出的是 ：分离出的细菌菌株中有18.6%，其次是5.8%的 属、4.6%的 属、4.6%的 种、3.5%的 属、 属和2.3%的 属。值得注意的是，在产褥期第7天，正常产犊奶牛每毫升菌落形成单位（CFU/mL）的平均值为74×10 CFU/mL，而难产奶牛为29×10 CFU/mL。在所有情况下，产后前14天记录的细菌总数显著增加，难产产犊的奶牛中细菌数量更高。为了进行统计分析，使用SPSS 16软件进行独立t检验（ < 0.05）。该研究的对象是荷斯坦奶牛根据顺产/难产类型的细菌负荷情况。
