In recent years, pig husbandry has gained ground in comparison to production of ruminant animals. In Tanzania more than 90 per cent of the country’s two million pigs are kept by small-scale farmers under both confined and free-roaming management systems as a sole enterprise in urban areas or as a component of a mixed crop-livestock system. Major constraints include poor management due to lack of knowledge by farmers, inadequate nutrition and limited veterinary services which result in heavy disease burdens. At least 10 species of endo-parasites have been identified in Tanzania’s pig stock. Mange mites, ticks, lice and fleas infest a large proportion of pigs. Some five species of trypanosomes are blood parasites mainly in the northern part of the country. Constraints imposed by these parasites must be mitigated in order to improve the productivity of pigs in the country. This paper reviews the national literature on the subject.
