The endometritis form of uterine infection is considered as a common reproductive disorder deleterious to the reproductive performance of dairy herds. A wide variety of treatments with controversial results have been reported for endometritis, including local or systemic administration of antibiotics or disinfectants as well as hormone application. These treatments have side effects on endometrium, and antibiotic residues are found in milk following intrauterine and systemic antibiotic therapies. The aim of this study is to evaluate the possible effects of the mixed essential oil of Satureja bachtiarica Bunge, Artemisia Aucheri Boiss and Syzygium aromaticum (L.) Merr. & L.M.Perry on treatment of clinical endometritis in dairy cattle. One hundred and twenty cows with clinical endometritis were selected and randomly assigned to one of the following three groups: the HM group received mixed herbal essential oils, the OX group received 2.5 g oxytetracycline HCl, and the EX group received 1 g of ceftiofur sodium, all by intrauterine injection. The cleaning and first service conception rate was significantly higher in HM group than the EX, whereas the mean open days were lower in HM than the EX group. The number of service per conception was also significantly lower in HM group than OX and EX groups. In general, reproductive performance after herbal treatment was quite comparable to chemical antibiotic therapy and even better in some other reproductive indices. The mixed essential oils treatment represents an effective potential alternative to postpartum therapy for cows with clinical endometritis.

The appropriate effects of supplementation with minerals and vitamins on reproductive performance have been well studied before. The object of this study was to determine the effect of prepartum supplementation with vitamin E and selenium on milk yield and reproductive performances in dairy cows. In this study, 247 Holstein dairy cows were selected during prepartum transitional period and divided randomly into two groups. A group: a single injection of vitamin E + selenium at Day 250 of gestation and B group: two injection of vitamin E + selenium at days 250 and 270 of gestation. Indices of reproductive performance, milk yield and milk somatic cell count were compared between two groups. There was no significant difference in reproductive indices in B group compared to A group. Milk yield in different month of after calving and somatic cell count did not show any significant difference between groups. In summary, the results of this study showed that use of extra supplementation with vitamin E and selenium in prepartum period did not significantly affect reproductive parameters, milk yield and the somatic cell count.

The objective of the present study was to evaluate e the reproductive performance following the treatment protocols for ovarian follicular cysts according to the status of endometritis in dairy cows.. A total of 94 dairy cows with ovarian follicular cysts with considering the condition of endometritis were randomly divided into three treatment groups: Group 1: Control group did not receive any treatment, Group 2 that received 200 µg Gonaderoline plus 500 µg Cloprostenol and Group 3 that received the same hormone therapy plus aspiration of ovarian follicular cysts. The response to treatment of ovarian follicular cyst, reproductive performance of cows with, without endometritis and total cows was statistically analyzed using the SPSS software. A higher percentage (68.9%) of cows with ovarian cysts had endometritis. The percentage of cows that respond to treatment of ovarian follicular cyst was significantly higher in cows of with endometritis and total cows in hormonal applications plus cyst aspiration group (87.5% and 82.6%, respectively) compared to control (42.9% P= 0.02 and 46.2%, P= 0.02 respectively) and only hormonal applications (52.5% P= 0.01 and 59.6%, P= 0.04 respectively) groups, but no statistically significant differences were found in reproductive performance among the treatment groups. According to our results, the presence of endometritis at the same time as ovarian cysts has no significant negative effect on the treatment of ovarian follicular cysts in cow and the treatment of cyst with treatment of follicular cysts with hormonal applications plus cyst aspiration method can be used successfully in different endometritis conditions.
