Abstract

At Abu-Soweir and El-Ferdan villages in Ismailia province, this study invloved 32 dystocias, 30 cows with retained placenta compared to 10 cows did normal calving and placental drop. Maternal dystocia accounted for 43.75% of all dystocias compared to 56.25% due to fetal factors. Dystocia was associated with a high significant (P<0.01) decrease in the serum levels of oestradiol -17B and cortisol compared to a higher concentration of progesterone. An association between high significant (P<0.01) decrease in the concentrations of selenium and B carotene and retained placenta was found. Response to treatment revealed that estrumate was successful in relieving 70% of dystocias caused by closed or insufficient cervical dilation. Caesarotomy was also successful in relieving 42.85% of maternal dystocia with a maternal death rate 11.1%.16.7% of fetal dystocia was relieved by hysterotomy compared to 61.1% and 22.2% relieved by correction and fetotomy respectively.
For retained placenta, estrumate injection immediately after the manual removal of the retained placenta 24 hours postpartum proved to be the best regime of therapy. Both dystocia and retained placenta were associated with a marked prolongation in the calving - conception interval
