Financial losses caused by ovine fasciolosis in the Ethiopian highlands (original) (raw)
Summary
An estimate of the economic loss due to ovine fasciolosis in the Ethiopian highlands was made based on available data on mortality, weight loss, reduced reproductive efficiency and liver condemnation at slaughter. The economic effects of fasciolosis were identified and models for estimating the financial loss presented. Ovine fasciolosis losses were estimated at 48·4 million Ethiopian Birr per year of which 46·5, 48·8 and 4·7% were due to mortality, productivity (weight loss and reproductive wastage) and liver condemnation, respectively. These losses can be reduced substantially by fasciolosis control programmes that may include the use of anthelmintics, grazing management and nutritional supplementation.
Résumé
Une estimation de la perte économique due à la fasciolose ovine dans les Highlands d'Ethiopie a été faite sur la base de données disponibles sur la mortalité, la perte de poids, la réduction de l'efficacité de reproduction et la saisie de foies à l'abattage. Les effects économiques de la fasciolose ont éte identifiés et des modèles pour l'estimation des pertes financières ont été présentés.
Les pertes dues à la fasciolose ovine ont été estimées à 48,4 millions de Birrs éthiopiens par an, dont 46,5, 48,8 et 4,7 p. 100 étaient dus respectivement à la mortalité, la productivité (la perte de poids et la perte de reproduction) et à la saisie de foies.
Les pertes peuvent être réduites de façon substantielle à l'aide de programmes de lutte contre la fasciolose pouvant inclure l'utilisation d'anthelminthiques, la gestion des pâturage et une complémentation alimentaire.
Resumen
Se llevo a cabo un cálculo de las pérdidas economicas causadas por fasciolosis en la tierras altas de Etiopia, basado en información sobre mortalidad, perdidas de peso, reducción de la eficacia reproductora y decomisos de higados en el matadero. Se identificaron los efectos económicos de la enfermedad, presentándose modelos para estimar dichas perdidas económicas. Las pérdidas por fasciolosis ovina fueron estimadas en 48·4 millones de Birr/ano, des los cuales 46·5, 48·8 y 4·7% se debieron a mortalidad, productividad (pérdidas de peso e ineficacia reproductora) y decomiso de hígados, respectivamente. Estas pérdidas pueden reducirse sustancialmente instaurando programas de control con antihelmínticos, manejo de praderas y suplementación nutricional.
