Health and performance of trypanotolerant cattle breeds exposed to quantified trypanosomiasis risk at five sites within the African Trypanotolerant Livestock Network
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...
