An intramuscular injection of 5 mg dinoprost caused a discharge of uterine fluid (cloudburst) in 49 cases of hydrometra in goats during the breeding seasons of 1988, 1989 and 1990. A spontaneous oestrus after the cloudburst was allowed to occur in 20 of the goats; in nine (45 per cent) of them a hydrometra recurred, three conceived at the first oestrus and eight returned to oestrus. Oestrus was induced in 29 other cases by means of a second intramuscular administration of 5 mg dinoprost, 12 days after the cloudburst. In this group a hydrometra recurred in only one goat, 14 goats (48 per cent) conceived at the first oestrus and 14 returned to oestrus. Of the animals in which a pseudopregnancy occurred once or more during the same breeding season, 85 per cent became pregnant, compared with 97 per cent of unaffected older goats. The mean number of kids of the goats that became pregnant and kidded after treatment for hydrometra was 2.0 compared with 2.3 for unaffected animals. The results indicate that a single administration of prostaglandin is not a satisfactory therapy for a hydrometra, but that reproductive performance improves when a second injection is given 12 days after the cloudburst.

Hydrometra or pseudopregnancy is characterised by the accumulation of aseptic fluid within the uterus and a persistent corpus luteum. In goats the diagnosis can be easily made by ultrasound. The incidence of hydrometra was investigated in three herds of dairy goats, in two of them during one oestrous season and in the other over three years. The incidence varied between 3.0 per cent and 20.8 per cent with a mean incidence of 9.0 per cent. The incidence in older goats was significantly higher than in yearlings, and the chance of a hydrometra increased with the age of the goats. The finding, during one year, that a pseudopregnancy occurred more often after an induced ovulation, was not repeated in another year.

Previous experiments with bromocriptine suggested that prolactin plays a role in the aetiology of pseudopregnancy in goats. Serum prolactin concentration was measured in a herd of white Dutch dairy (Saanen) goats when hydrometra (a typical characteristic of pseudopregnancy) was diagnosed by ultrasound, during the spontaneous development of pseudopregnancy, and in normally reproducing goats during the breeding season. In the normally reproducing does the prolactin concentration decreased at the beginning of the breeding season. In 12 of 14 pseudopregnant goats the prolactin concentration was within the range observed in the normally reproducing goats on the day that hydrometra was diagnosed. In two goats the prolactin concentration was low during the first few weeks of pseudopregnancy and in a third it fluctuated. There was no correlation found between the concentration of prolactin and the development or the presence of a persistent corpus luteum. These results suggest that prolactin does not play a crucial role in the aetiology of pseudopregnancy in the goat.

Abnormalities of the reproductive tract of female sheep were studied by examining 9970 reproductive tracts from cull ewes and 23,536 tracts from nulliparous sheep (prime lambs) over a period of 12 months in abattoirs in south-west England. Overall, 3.37 per cent of the tracts were pregnant (8.11 per cent of cull ewes, and 1.36 per cent of nulliparous sheep), with a peak incidence between September and December. A total of 655 ewes (6.57 per cent) and 459 nulliparous sheep (1.95 per cent) had acquired abnormalities of the reproductive tract. Within these totals, abnormalities of the ovaries accounted for 3.51 per cent (for the ewes) and 10.68 per cent (for the nulliparous sheep) of all the abnormalities, and abnormalities of the ovarian bursa and uterine tube accounted for 42.1 per cent (for the ewes) and 5.23 per cent (for the nulliparous sheep). In addition, uterine lesions (hydrometra and metritis) accounted for 9.92 per cent (for the ewes) and 13.51 per cent (for the nulliparous sheep); lesions of the cervix and vagina (total of 1.44 per cent) and Cysticercus tenuicollis cysts associated with the reproductive tract (total of 3.05 per cent) were less common. Among the ewes the most common ovarian lesions were ovulation tags, and follicular cysts were the most common in nulliparous animals. Lesions such as bursitis, parametritis and abscesses of the reproductive tract were much more common in cull ewes than in nulliparous sheep, probably having arisen from peripartum infections. Hydrosalpinx and hydrometra, in which the intraluminal fluid was clear, were present at relatively high incidence in nulliparous animals, but not in cull ewes. The proportion of tracts containing macerated fetal remnants (2.14 per cent of all abnormalities in cull ewes) was lower than expected. It was considered that the functional significance of many of the lesions, such as ovulation tags and C tenuicollis cysts, was likely to be low, although in some cases of the latter calcification of the cyst had occluded the uterine tubes. Other lesions, notably hydrosalpinx, bursitis and metritis were likely to have made the affected animals sterile. The acquired abnormalities were therefore more significant in terms of individual animal infertility than as a major cause of infertility in flocks.
