- W1996038070 abstract "In Southern Africa, where 150,000 working donkeys provide an important alternative to mechanisation in resource-poor communities, very little is known about their helminth status, or about the impact of helminths on their work output. The aim of this study was to investigate the helminth status of working donkeys under different management systems. Donkey owners in three different areas (one rural and two semi-rural) of the Moretele 1 district of North-West Province, South Africa, were visited and structured interviews were used to assess the management systems under which the donkeys were kept. Faecal samples were collected from 93 donkeys in the study once a month for 14 months. Faecal samples were analysed for nematode and trematode eggs and cultured to produce third-stage larvae for the identification of the nematode species. Final comparisons between management system subgroups, as well as between areas, age groups and sexes were made. Four management systems were identified. (1) The first system identified consisted of donkeys which were kept in a small yard at all times. They were fed hay but no supplementary food. (2) The second system consisted of donkeys which were allowed to roam freely around the village most of the time and rounded up and held in an enclosure when needed for work. (3) The third system was identical to the second management system except that the donkeys were given supplementary food during winter. (4) The fourth system was only found in the one area where each owner owned 10 ha of land and here the donkeys were allowed to roam freely on the owner's land and brought into enclosures prior to working. Helminth species composition and faecal egg count numbers differed between these four systems. The main difference noted was that donkeys from management system one showed significantly higher numbers of strongyle eggs and higher percentages of some of the strongyle larvae. Management system two had a higher Strongyloides mean egg count and prevalence than the other areas. Parascaris and Gastrodiscus egg counts differed between all four systems. Since the results showed differences in the number and species of helminths in donkeys kept under the four management systems, suggestions are made as to which management system would facilitate reduction of helminth parasites in the animals. Although supplementary feeding in Moretele 1 is fairly rare, it would seem that donkeys which do have access to better food resources have lower egg counts than donkeys on limited grazing." @default.
