Item Comparison of production performance and tolerance to helminthosis of toggenburg and Norwegian crossbred goats under smallholder production systems in Tanzania(Taylor & Francis Group, 2015-08) Chenyambuga, S. W; Shija, D. S; Kusiluka, L. J. M; Lekule, F. PThis study was carried out to compare the growth rate, lactation performance and tolerance to gastrointestinal nematode infection of Toggenburg and Norwegian breeds in Kongwa district, Tanzania with a semi-arid environment and Mvomero district with a sub-humid environment. Milk production of does, nematode eggs per gramme of faeces (EPG) and packed cell volume (PCV) were recorded for one year in 57 Toggenburg crosses and 72 Norwegian crosses raised by 107 small-scale farmers in the two districts. Kid body weights and mortality were recorded for 65 kids. Kid birth weights of Norwegian crosses (3.07 ± 0.13 kg) and Toggenburg crosses (2.91 ± 0.14) were not significantly different (P > 0.05). The growth rate of Norwegian crossbred kids from birth to one year (54.26 ± 4.33 g/day) was lower than that of Toggenburg crossbreds (61.50 ± 4.38 g/day). Toggenburg crossbred does produced slightly higher average daily milk yield (0.81 ± 0.08 l/day) compared to Norwegian crossbred does (0.64 ± 0.09 l/day). Norwegian crosses had higher mean EPG (211.78 ± 0.02) and lower PCV (23.93 ± 0.96%) than the Toggenburg crosses (129.51 ± 0.02 EPG and 26.71 ± 0.99% PCV). It is concluded that the Toggenburg crosses are relatively better suited to the smallholder production environments in rural areas of Tanzania compared to the Norwegian crosses.Item Helminthosis in local and cross-bred pigs in the Morogoro region of Tanzania(Elsevier, 1997-01) Muhairwa, A.P; Mtambo, M.M.A; Kambarage, D.M; Elsrony, K; Kusiluka, L. J. MWe investigated the prevalence, burden and types of gastro-intestinal helminths in 424 local and cross-bred pigs kept under different management systems in two climatic zones in the Morogoro region of Tanzania. Coprological examination revealed that 53% of the pigs excreted hehninth eggs in their faeces. The median eggs per gram of faeces (EPG) was 500 (range 100-22000). Local breeds in the Mgeta location with tropical highland climate showed signifi- cantly higher prevalence (P < 0.001) and median EPG values ( P < 0.001) than the cross-bred animals in the semi-arid area. There was no significant difference in the prevalence (P = 0.90) of helminth infection and egg outputs (P = 0.78) in cross-bred pigs raised under the small-scale and semi-mtensive management systems in the semi-arid zone. Piglets showed significantly lower prevalence of helminthosis (P < 0.001) than the weaners, growers and adults in both local and cross-bred animals. Median EPGs of growers and adult animals were significantly higher than those of piglets and weaners (P = 0.006). The prevalences of various hehninth species were Oesophagostomum sp. (40%), Ascaris suum (12%), Strongy loides ransomi (9% ) and Trichuris suis (St% ). 0 1997 Elsevier Science B.V.Item Preliminary investigation on accessibility and ultilisation of water in selected villages in Dodoma rural and Bagamoyo districts, Tanzania(2003-10) Kusiluka, L.
