A study was conducted to assess the correlation between criteria of trypanotolerance and production. N'dama post weaner cattle with different weights and from different age groups were studied for weight gain, packed cell volume (PCV) and for the presence of trypanosomes. The analysis approach wa...

The health and performance records of cattle and sheep used were collected over a three-year period, 1984-1986, at four network sites. Three of the sites, Avetonou (Togo), Boundiali (Cote d’Ivoire) and Mushie (Zaire) were chosen because of their high mean trypanosome of the live weight performanc...
