Summary
An experiment was conducted in The Gambia to compare trypanosomosis incidence between zebu and N'Dama cattle. It was considered important to compare the 2 breeds under identical management conditions and the animals were maintained together at 3 locations, traditionally managed and under a range of tsetse challenges. The results show that trypanosomosis incidence was significantly higher in zebu than in N'Dama. Titre of antibody againstTrypanosoma vivax measured by an IFAT showed a significant difference between zebu and N'Dama. Variations in packed cell volume were greater in zebu than in N'Dama.
Résumé
Une expérience a été effectuée en Gambie pour comparer l'incidence de la trypanosomose entre des Zébu et des bovins N'dama. Il a été considéré comme important de comparer les 2 races dans des conditions d'élevage identiques, les animaux étant regroupés ensemble en 3 endroits, en élevage traditionnel et avec une pression glossinaire identique. Les résultats montrent que l'incidence de la trypanosomose a été plus élevée chez les Zébu que chez les N'dama. Le taux d'anticorps antiTrypanosoma vivax, mesuré par l'épreuve indirecte des anticorps fluorescents, a montré une différence significative entre les 2 races. Les variations de l'hématocrite ont été plus grandes chez les Zébu que chez les N'dama.
Resumen
Se llev\(\dot o\) a cabo un experimento en Gambia para comparar la incidencia de tripanosomiasis en ganado cebú y N'Dama. Se consideró importante comparar las 2 razas bajo condiciones similares, en tres lugares diferentes con descargas minimas y máximas de tsetsé. Los resultados mostraron que la incidencia de tripanosomiasis fue significativamente mayor en cebú que en N'Dama. Los titulos de anticuerpos contraTrypanosoma vivax medidos mediante la prueba indirecta de anticuerpos fluorescentes, fueron significantivamente diferentes entre cebú y N'Dama. La variación en el volumen corpuscular celular fue mayor en cebú que en N'Dama.
