A study of the genital organs of the female dromedary (Camelus dromedarius)

Abstract

Summary. Camels (416 pregnant, 118 non-involuted post partum and 730 nonpregnant) were examined post mortem. Large follicles (>10 mm), small follicles (5\p=n-\10mm) and non-functional ovaries were observed in 144 (20\m=.\7%), 127 (18\m=.\3%) and 424 (61\m=.\0%)respectively out of 695 normal non-pregnant organs. Season did not exert any significant influence on the frequency of these groups. Recently formed and regressing CL after sterile mating were occasionally seen. Corpora albicantia (3\p=n-\15mm) were the most frequent structures observed in non-pregnant organs of parous camels as well as in pregnant tracts, together with the CL of pregnancy: 17% of ovaries contained more than one luteal structure. Pregnancy was easily recognized as early as 40\p=n-\45 days of gestation because of the marked swelling of the left uterine horn in which 99\m=.\52%of the pregnancies were located.

Slaughterhouse survey of culled female camels (Camelus dromedarius) in southeast Algeria: Fetal wastage and pregnancy characteristics

“…The frequency of unilateral and bilateral ovulations observed in the present study was in agreement with the report by El-Wishy (1988) in which the CLs were unilateral in 93.3% of dams. In our study, the CL distribution was equal between the left and right ovaries, similar to the report of El-Wishy (1988) and Tibary and Anouassi (1997).…”

“…In female camels, successful pregnancy following ovulation from the left ovary is more common (Ali 2010). Consistent with other studies (Shalash, 1965;Musa and Abusineina, 1976;El-Wishy, 1988;TibaryandAnouassi, 1997), pregnancy was located in the left uterine horn in 99.5% of cases in the present study.…”

“…was significantly higher in females compared to males (p = 0.027) ( Table 2). This can be explained by the immunosuppression of females which may occur during pregnancy and lactation periods [41], which could last up to two years [44].…”

“…and is always the site of implantation (4), and they also share the same diffuse, non-invasive epitheliochorial placenta (18,20). In contrast, however, New World Camelids are small, cloven-hoofed, and have a dense, fine wool coat which enables them to survive at the low temperatures of the deserts of the high Andes, whereas Old World Camelids are large, slow, have a single footpad and cope ideally with extreme temperatures and harsh food availability of the low-lying deserts of Arabia and Africa.…”
