Influence of retained fetal membrane treatment on days open and conception rate in dairy cows

The aim of the study was to compare two different treatment of retained fetal membrane and their effect on the insemination index and days open. Research was conducted on 225 cows of Holstein breed aged between 2 to 6 years, selected from ten dairy cow farms in northwestern Croatia. The cows were divided into 3 groups, with 75 cows per group. In group A placenta was manualy extracted following intrauterine application of antibiotic 12-24 hours after calving (Geomycin F®, Veterina, Croatia) and supportive therapy, if necessary. In group B the fetal membrane wasn’t extracted. The treatment consisted of intrauterine soluble oblet application 2-3 times every 48 hours, starting 12-24 hours after calving (Geomycin F®, Veterina, Croatia). The Group C (control) consisted of cows with physiological puerperium, without retained placenta. In our study the length of days open and insemination index differ significantly (P<0.05) between group A (136, 81 ± 6, 19 ; 2, 21) in comparison to the group B (123, 37 ± 6, 09 ; 1, 89) and group C (121, 87 ± 5, 20 ; 1, 78). It could be concluded that treatment of choice for retained fetal membrane in Holstein cows consisted of intrauterine soluble oblet application without manual extraction of fetal membrane. Manual extraction of fetal membrane significantly extended days open and increased insemination index.
