SUMMARY An abattoir survey of 850 female genital organs of imported camels was conducted at the Kano abattoir between October 1987 and April 1988 . An incidence of 4 .49% of disorders was recorded, including follicular cystic degeneration (0 .12%), ovarian haemorrhagic cysts (0 .47%), pyometra (0 .35%), early embryonic mortality (0 .12%), endometrial haemorrhages (0 .47%), fetal maceration (0 .12%), abscess (0 .24%), vulvar tick infestation (1 .77%) and cervical hypoplasia (0 .12%) .

INTRODUCTION Disease factors and management are the most important causes of infertility in camels (Shalash, 1965) and may take the form of specific diseases affecting reproductive organs, or non-specific diseases that affect reproduction by reducing the efficiency of the animal as a whole (Shalash, 1980) . There is an increased requirement for camel meat as a source of animal protein in Nigeria . At the Kano abattoir alone, 19 762 and 16 999 camels were slaughtered in 1986 and 1987 respectively (Ribadu, 1988) . The majority of the camels slaughtered at this abattoir were imported into Nigeria from neighbouring Niger and Chad Republics . There is a dearth of information on reproductive disorders of camels in Nigeria, hence the undertaking of this study .

MATERIALS AND METHODS Female genital tracts of 850 camels were collected from the Kano abattoir between October 1987 and April 1988 and examined for abnormalities . The composition of the population as studied was not known . *Present address : Department of Veterinary Clinical Science, University of Liverpool, Leahurst, Neston, South Wirral L64 7TE, UK

FEMALE GENITAL DISORDERS IN CAMELS

All tracts were incised from the vagina to the oviduct and the lumen examined . Where a tract was found to be abnormal, the lesion was recorded . The ovaries were also examined for gross abnormality . Pus from three cases of pyometra was inoculated on blood and MacConkey agar plates and incubated aerobically and anaerobically at 37 ° C for 48 h . Identification of the organism was made by conventional methods (Cowan, 1974) .

RESULTS The types and incidence of gross pathological conditions of the female genitalia are summarized in Table I . Gross abnormalities were recorded from 38 of 850 reproductive organs examined .

The fluid of the ovarian follicular cysts ranging from 17 to 22 .5 ml were slightly yellow to amber coloured . In the cases of pyometra the uteri were distended with thick creamy pus, from which Actinomyces pyogenes was isolated . The ticks observed at the vulva were identified as Hyalomma dromedarii .

DISCUSSION The overall incidence of genital abnormalities (4 .49%) is quite low compared with the results obtained in Egypt by Shalash (1965) and Nawito et al. (1967) who recorded an incidence of 19 .46% and 16 .72% respectively . El-Wishy (1988), however, recorded an incidence of 2 .77% from 1264 genital organs of camels in Egypt .

The isolation of A . pyogenes from all three pyometra cases is consistent with the observation by Hegazy et al. (1979) . Vulva tick infestation (1 .77%) was the most frequent abnormality recorded in this investigation .
