Heartwater (cowdriosis) is an infectious disease of domestic ruminants in Africa and the Carribean and is caused by a tick-borne intracellular rickettsial agent, Cowdria ruminantium. There is growing evidence that immunity of cattle to the disease is medicated by T. lymphocytes. Antigens that sti...

Trypanosomiasis is one of the most important diseases in African cattle. About 3 million cattle die every year by this disease. However, about 5 percent of the total African cattle have a natural resistance against trypanosomiasis. In a preliminary study markers linked to trypanotolerance have be...

In view of the low pasture productivity in the Central American humid tropics where cattle rearing is a major land-use activity, it is important to examine the potential of alternate feed sources for ruminant feeding. Erythrina berteroana Uban, locally known as poro, and green banana (Musa AAA) f...
