This paper deals briefly with the potential of cow traction in the Ethiopian highlands farming systems with particular reference to energy requirements and feeding and strategies. Examines cow energy requirements for work, maintainance, milk production, and pregnancy; and effect of draft work on ...

To test the feasibility of the use of dairy cows for draft the International Livestock Research Institute (ILRI) and the Institute of Agricultural Research (IAR) in Ethiopia have studied a herd of F1 Friesien x Boran crossbred cows on-station over three years together with on-farm experiments an...

Crop and livestock subsystems in the Ethiopian highlands interact with each other in many wasy. The livestock subsystem has output, input, asset, and security and investment functions in the farming system. Animal traction and crop residues are the prominent binding elements of the crop and lives...

In Ethiopia, Boran and Arsi indigenous cows have been crossbred with Friesian and, or, Jersey sires in an attempt to increase milk production, especially in the Highlands (Kiwawa et al., 1983; Beyene, 1984). However, significant increase in milk production from crossbred cows have been constraine...

Draught animals are the main integrative links between crop and livestock production systems in the highlands of Ethiopia. The highlands comprise only 40% of the country's total land area but carry 79% of livestock heads and 80% of the human population results in higher pressure on the arable lan...

In Ethiopia, the use of crossbred cows for traction could improve total on-farm production by decreasing the need to maintain draft oxen year-round and a fallower herd to supply replacement oxen, provided that lactation and reproduction are kept at levels comparable to non-working cows. In a stud...

Production performance of cows is an important factor which determines whether cows are adopted for draft power. Working cows could perform at higher levels of efficiency than oxen, but only if nutrient inputs are adequate to meet their greater requirements, and milk production and reproduction a...
