Item Eimeriosis in dairy cattle farms in Morogoro municipality of Tanzania(Elsevier Science B.V., 1996-10) Muhairwa, A.P; Chibunda, R.T; Kambarage, D.M; Mtambo, M.M.A; Kusiluka, L.J.M; Kazwala, R.RCoccidial oocysts were detected in 35% of 445 cattle in four medium-scale and 20 small-scale dairy farms in Morogoro municipality, Tanzania. The highest prevalence (56%) was observed in animals aged between 5 and 18 months, whereas lower prevalences were observed in calves (29%) aged between 12 days and 4 months and adults (30%). No coccidial oocysts were detected in calves less than 12 days old. The oocyst output was high in calves, followed by weaners; adults had the lowest oocyst output. The number of oocysts per gram of faeces was significantly higher (P < 0.001) in diarrhoeic animals than in non-diarrhoeic animals, and more so in young calves. Eimeria species infecting the animals included Eimeria bovis (68%) and Eimeria zuemii (57%), Eimeria ellipsoidalis (25%), Eimeria cylindrica (23%), Eimeria aubumensis (22%), Eimeria alabamensis (12%) and Eimeria subspherica (5%). Mixed infections involving two or three species were common. Our findings indicate that eimeriosis is common in cattle in Morogoro municipality. Published by Elsevier Science B.V.Item Using free and open source software for e-Learning system (FOSES) in Tanzania(2006-02) Lwoga, Tandi Edda; Sanga, Camillius; Kazwala, R.R; Mganilwa, Z.MThe implementation of e-Learning software in Tanzania’s universities as well as other developing countries is still very low even though there are plenty Free and Open Source Software (FOSS) that can cater for this purpose. Among ten universities, only the University of Dar Es Salaam (UDSM) has managed to implement the e-Learning software in Tanzania by using WEBCT and Blackboard are e-Learning proprietary software. This study therefore discusses how the Tanzania Universities can establish and implement the e-learning technology with a case study of the Sokoine University of Agriculture. Specifically, this study describes the early evaluation steps that were observed during the adoption of the e-learning platform at SUA. The extensive literature review, experience gained from other universities, and the analysis of the available open source e-learning software were used for the selection and further improvement of the e-learning platform at SUA. Challenges that are delaying the implementation of e-learning platform at SUA are also discussed, and recommendations are given upon them. It is anticipated that the findings of the study will be used by all stakeholders in planning cost-effective and efficient ICTs implementations for general improvement of education sector from national level up to district level.
