دراسة مقارنة لبعض العلاجات الموضعية لالتهاب بطانة الرحم في الأبقار

الملخص EN

The present study was conducted on 57 local breed cows suffering from various degrees of endometritis.

The clinical examination included visual examination of vagina supported by uterine palpation per rectum; the laboratory examination included the bacterial isolation from the uterine swabs and histopathological examination of the uterine biopsies.

Animals were randomly divided in to three groups of 15 cows each and 12 cows were considered as a control group received no treatment and observed for three consecutive estrous cycles.

The first group was treated with a mixture of oxytetracycline (4 g) and tylosin (2 g), second group was treated with cephquenome sulfate 0.5 g, and the third group was treated with lugol's solution (30 ml) 2 %.

These treatments were applied as a single intrauterine infusion and the clinical recovery was evaluated at the next estrous cycle by considering the absence of abnormal vagina discharge as an indicator of clinical recovery.

Cows that showed clinical cure were inseminated artificially and the pregnancy diagnosis was preformed at least 75 days after insemination by rectal palpation.

Retained placenta was the most important predisposing factor of endometritis 50.8 %, results of the bacterial examination demonstrated that E.

coli was the most prevalence bacteria (27.4 %).

Histopathological examination of uterine biopsy showed a high incidence ratio of chronic endometritis (42.1 %).

Results of the treatment showed a higher response and conception rate in the second group (using of cephquenome) 73.3 % and 63.3 %, respectively, followed by first group (using mixture of oxytetracycline and tylosin) 60 % and 55.5 %, respectively, then the third group (using of lugol's solution) 40 % and 50 %, respectively.

The lowest cure and conception rates were observed in the control group 25 % and 33.3 %, respectively.

This study pointed out a positive relationship between the nature of the vaginal discharge and each of the bacteriological and histopathological examination and revealed the importance of the early treatment of endometritis especially using of cephquenome sulfate.
