RESUMEN
Bilateral ovariectomy was performed in three parous, non-pregnant camels. Intrauterine and intraabdominal pressure changes were recorded using balloon-tipped catheters. Uterine contractions were induced and maintained in the ovariectomized camels by daily intramuscular injections of 5 mg oestradiol benzoate throughout the experimental period. The frequency of uterine contractions varied from 6 to 9 per minute, whereas the amplitude varied from 2 to 3 kPa in all the animals. Inducing hypocalcaemia to a level of 0.5 mmol/L by Na2EDTA reduced the amplitude of the contractions to below 1 kPa (p < 0.001). The frequency of the contractions was not affected.

During oestrous cycles of the camel, spontaneous uterine contractions were correlated significantly with plasma oestradiol-17 beta concentration. Ovariectomy in the camel resulted in a decreased plasma concentration of oestradiol-17 beta (< 15 pg ml-1) and progesterone (< 0.1 ng ml-1) and caused complete cessation of uterine activity. Daily administration of oestradiol benzoate (5 mg, intramuscularly) increased the plasma concentration of oestradiol-17 beta (> 45 pg ml-1) and increased the frequency and amplitude of uterine activity. Coadministration of progesterone (100 mg, intramuscularly) increased the plasma concentration of progesterone (> 4 ng ml-1) and increased the frequency but not amplitude of uterine activity. It is suggested that uterine activity in the camel is correlated with the circulating levels of oestradiol-17 beta and progesterone.

Ectopic mammary tissue was described in ten goats belonging to the Nubian and Syrian breeds. This consisted of multiple cavitations containing white milky fluid, which greatly resembled milk in colour, odour and composition. Histologically, the tissue was composed of alveoli lined by cuboidal epithelium and contained pinkish staining secretion. Surgical removal of the tissue was achieved without complications.

Two hundred eighteen genital tracts of slaughtered female camels were collected and examined. Infundibular cysts were observed in 35 tracts (16%); these were either unilateral (22 cases) or bilateral (13 cases) all containing fluids of different consistencies. The morphological and histological structures of the cysts were recorded. The bacteriological investigation and physicochemical analysis of cyst contents were carried out. Aeromonas hydrophila was isolated from 68.5% of cases. Rectal palpation and ultrasound technique were compared for the diagnosis of the cysts antemortem.

A bilateral scrotal hysterocele is described in a male pseudohermaphrodite goat. The surgically removed tests were devoid of spermatogenic cells. Serum androgens showed normal levels before surgery but dropped following removal of the gonads.

A functioning udder is described in a 7-year-old Nubian male goat. The defect was not observed in any of his several off-spring. His semen had few dead sperm and his serum testosterone level was low. The udder was removed surgically. Histologically, the udder showed dense connective tissue lobules composed of acinar or tubulo-acinar structures and the teat orifice had no muscle sphincter.

Oestrous cycles were followed by blood progesterone titration and the occurrence of pregnancy was observed after mating in three groups of mature female Nubian goats. Two groups of 4 and 3 goats each were experimentally infected by an in utero injection of either a Staphylococcus aureus or a Mycoplasma capricolum strain of caprine origin. A third group of 4 goats served as a control. Both bacterial infections persisted in all experimental animals, except one, for at least 70 days. As a result, there is a shortening of the first two cycles and progesterone concentration was lower than in the controls. Only one inoculated goat became pregnant after the third oestrus. It is suggested that bacterial inflammation of the uterus may thus modify the oestrous cycle through the prostaglandin pathway.
