Studies on Trypanosome-resistant cattle. II. The effect of Trypanosomiasis on N'dama, Muturu and Zebu cattle

Summary

Two experiments were carried out to compare the ability of N'dama, Muturu and Zebu cattle to withstand infection with African pathogenic trypanosomes transmitted by wild-caughtGlossina morsitans submorsitans.

Observations on parasitaemia, blood values, body weight and clinical condition indicated that the Zebus were more severely affected by the trypanosome infections than either the N'damas or the Muturus, and the Muturus were more severely affected by the disease than the N'damas.

Observations on breeding and growth of the three varieties of cattle reported in a previous communication, and on their resistance to trypanosomiasis in the present reported paper, indicate that the N'dama has more qualities of potential practical value than the Muturu and that the breed could be used to a greater extent in livestock development programmes in tsetse-infested areas of West and Central Africa than it is used at present.

Etudes sur le bétail trypano-résistant. II. Action des trypanosomoses sur le bétail N'Dama, Muturu et Zébu

Résumé

Deux expériences ont été faites pour comparer la possibilité du N'Dama, du Muturu et du Zébu de résister à l'infection par les trypanosomes africains pathogènes transmis par desGlossina morsitans submorsitans sauvages.

Les observations sur las parasitémie, les constantes sanguines, le poids corporel et les signes cliniques ont montré que le Zébu était beaucoup plus sévèrement touché par ces affections que le N'Dama et que le Muturu et que ces derniers étaient beaucoup sensibles à la maladie que le N'Dama.

Il résulte des observations déjà faites sur la reproductions et le poids des veaux de ces trois variétés de bétail rapportées dans une précédente observation ainsi que de leur résistance aux trypanosomoses qui fait l'objet de cette relation, que le N'Dama dispose d'un meilleur potentiel de production que le Muturu et que cette race (N'Dama) pourrait être beaucoup plus utilisée pour le développement intensif de l'élevage dans les régions infestées de l'Afrique Centrale et de l'Ouest qu'elle ne l'est actuellement.

Estudios en bovinos resistentes a la trypanosomiasis II. El efecto de la trypanosomiasis en el ganado N'Dama, Muturu y Cebu

Sumario

Se Ilevaron a cabo dos experimentos para comparar la abilidad del ganado N'dama, Muturu y Cebú para soportar una infección con trypanosomas patogénicos del Africa transmitidos porGlossina morsitans submorsitans atrapadas en el estado silvestre.

Las observaciones sobre parasitemia, valores sanguineos, peso corporal y condicion clínica indicaron que el ganado Cebú fue mas severamente afectado por las infección a trypanosomas que el ganado N'dama o Muturu, y que el ganado Muturu fue mas severamente afectado por la enfermedad que el ganado N'dama.

Las observaciones sobre la reproducción y el crecimiento de las tres variedades de ganado reportades en una communicación previa y sobre sus resistencias a la trypanosomiasis reportadas en la presente comunicación, indican que el ganado N'dama tiene mas cualidades de valor potencial práctico que el ganado Muturu, y que esta raza puede ser usada en mayor escala en programas de desarrollo de ganadería en areas infestadas por moscas tsetse tanto en Africa Central como en Africa Occidental.
