Comparative and pathological studies on the reproductive tract of Algerian ewes and goats [electronic resource].

Includes references.

This study was planned to investigate the common pathological lesions in the ovary, the oviduct, the uterus and the cervix, (vagina was excluded) in apparently healthy adult slaughtered ewes and goats. The genital organs of six hundred thirty nine ewes and goats from Algerian breeds at different ages from six months to three years old were collected from Tiaret abattoirs. From 486 genital tracts of ewes, there were pathological changes in 126(25.92%) cases and 50(10.30 %) cases were gravid. In the ovary: The incidence of hypopplasia was 3.91%, paraovarian cyst 3.50 %, ovarian adhesions 1.86 %, and ovarian abcess, granulosa cell tumor were respectively 0.20%; In the oviduct: cyst of oviduct 0.83%, and salpingitis 0.41%. In the uterus: endometritis 2.26%, pigmentation of the uterine mucosa and fetal mummification were respectively 0.62%. In the cervix: tortuous cervix 10.50%, hypoplasia of cervical rings was 0.20%. From 153 genital tracts of goats, there were pathological changes in 37 (24.18%) cases and 24 (15.68%) cases were gravid. In the ovary: The incidence of paraovarian cyst was 5.22%, ovarian hypoplasia 4.60 % ovarian adhesions 1.96 %, the follicular cyst, the cystic ovarian degeneration and the ovarian abcess were respectively 0.65 %. In the uterus: endometritis 0.65%, fetal mummification 0.65 %. In the cervix: tortuous cervix 5.89%, hypoplasia and hypertrophy of cervical rings were respectively 1.96%), 1.30%. Tortuous cervix, ovarian hypoplasia were the most lesions observed in the genital organs of ewes. In goats, indeed of tortuous cervix, paraovarian cyst was the most lesion observed. The narrow nature of cervix in ewes more than in goats makes vaginal insemination difficult outside of estrous period. ovarian hypoplasia was detected in ewes more than in goats, it can be a factor of infertility when it is bilateral. Inflammatory changes in the uterus were also seen in ewes more than in goats. These pathological disorders are factors of infertility and cause a big damage and irreversible alterations in the endometrium if they are not early diagnose and adequately treat.
