Forty pregnant F1 crossbred dairy cows (20 Friesian X Boran and 20 Simmental X Boran) were stratified in a 2x2 diet X work factorial experiment (not working-not supplemented, NWNS; not working-supplemented, NWS; working-not supplemented, WNS; and working-supplemented, WS). Working cows pulled sle...

Many semiarid regions of Sub-Saharan Africa (SSA) are experiencing vast increases in human population pressure and urbanization. These augment the demand for agricultural products and have led to the expansion, intensification, and often closer integration of crop and livestock production systems...

For societies that depend on agriculture, the process of meeting current or future welfare demands should not continue without regard to the potential long-term dangers of land resource over-use. With an increasing human and animal population in the Ethiopian highlands development efforts so far ...

Inputs and outputs of traditional Horro cattle farming were monitored during the year 2001 in Boji District, West Wellega, located in the highlands of western Ethiopia. Inputs such as feeding and veterinary care were low. Milk and butter production, calf growth and animal work were also monitored...

African animal trypanosomosis is a parasitic disease that afflicts livestock across much of sub-Saharan Africa. The disease, primarily transmitted by the tsetse fly (Glossina spp.), causes morbidity and mortality in several species of livestock. It is particularly important in southern Burkina Fa...

With a limited number of cash cropping areas, sub-Saharan Africa has the lowest level of mechanization including animal-driven implements and use of tractors. In this paper previous research is reviewed to evaluate the economic and ecological constraints to animal draft cultivation. Results of pa...

Animal traction has been an integral part of most agricultural systems in Ethiopia for thousands of years. There is evidence that cattle were first used for ploughing in the latter part of the third millennium BC (Goe and Astatke, 1989). Today, the traditional cattle economy is directed mainly to...

The design and development of a reversible animal-drawn plough and a ridger is presented. The plough was developed on the basis of laboratory experiments reported earlier to determine optimum parameters for acurved implement. The basic design principles of conventional mouldboard ploughs and an a...
