Thirty-six West African Dwarf (WAD) goats were used to assess the effects of an experimental Trypanosoma congolense infection on their reproductive system. Estrous cycles were synchronised and when confirmed pregnant (n = 31), the does were randomly allocated into control and trypanosome-infected groups. After infection, the animals were carefully observed till parturition. Trypanosome infectio...

Hematological and biochemical parameters were determined in 82 West African Dwarf goats with foreign body rumen impaction (FBR) and 40 normal WAD goats without foreign body rumen impaction (WFBR) in order to evaluate their influence on the etio-pathogenesis of rumen impaction. The mean PCV (26.22%), RBC (9.03 X 106/µL), Hb (8.38g/dl) and MCHC (32.20g/dl) were significantly lower in FBR than in ...

This study was carried out to evaluate testicular ultrasound as a breeding soundness examination (BSE) and biometric tool for West African dwarf (WAD) buck goats. Twelve bucks of proven breeding capability were selected for this purpose. Scrotal circumferences of these animals were measured using a flexible tape. Testicular ultrasound was carried out on the transverse and longitudinal planes on...

A 17-year-old male captive West African dwarf crocodile (Osteolaemus tetraspis subsp. tetraspis) died 1 month after fighting with a penmate. Abrasions were present on the head and mandible. Necropsy revealed a vegetative valvular lesion of the left atrioventricular valve, miliary foci of necrosis in the endocardium and myocardium, multiple duodenal and rectal ulcers, and serous atrophy of body ...

OBJECTIVE To investigate correlates of resistance to GI nematode infection in Nigerian West African dwarf (WAD) sheep. METHODS Thirty three sheep were randomly assigned to two groups, A (n=27) which were used for experimental infections, and B (n=6) which served as uninfected control. Each infected animal received weekly escalating infections with infective larvae (60%Haemonchus contortus (H....

Ovarian activity was studied by laparotomy of 9 adult nulliparous goats in which oestrus was synchronized. Ovulation occurred in animals operated on 20-48 h from the onset of sexual receptivity. There was a mean ovulation rate of 1.57 ova per doe and the right and left ovaries had similar follicular activity in relation to sizes of follicles and ovulations.

Forty-eight West African Dwarf sheep and goats (twenty-four of each) with liveweights ranging from 8 to 15 kg were allotted in groups of eight to six diets containing 0%, 15%, 30%, 45%, 60% and 75% brewers’ dried grains (BDG) fed ad libitum together with 0.5 kg/head/ day fresh forage. After twenty-five weeks, all the animals were slaughtered and the carcass evaluated. Brewers, dried grains did ...

Available information on the mechanisms responsible for some reproductive lesions observed in experimental trypanosomiasis has not been fully elucidated. This work was undertaken to further study the histopathologic effects of Trypanosoma brucei infection on hypothalamus, adenohypophysis, ovary, uterus, placenta of the West African dwarf (WAD) doe and liver of aborted foetuses. Sixteen does (10...
