    We 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.
