Gebrewold, A.Alemayhu, M.Tegegne, AzageZerbini, E.Larsen, C.[On-farm performance of crossbred cows used as dairy-draught in Holetta area]On-farm performance of crossbred cows used as dairy-draught in Holetta area
Autor: Zerbini, E.

The principal objective of the workshop was to develop a funding proposal to implement transfer of the IAR/ILRI multi-purpose crossbred cows technologies to eastern African smallholders. The workshop proposed a formal means of co-ordinating and linkage and transfer mechanisms needed to ensure the...


Zerbini, E.[Objectives of the expert consultation]Objectives of the expert consultation

Forty pregnant F1 crossbred dairy cows (20 Friesian x Boran and 20 Simmental x Boran) were stratified in a 2 x 2 Diet x Work factorial experiment (not working, not supplemented; not working, supplemented; working, not supplemented; and working, supplemented). Working cows pulled sledges 100 days/...


Gemeda, T.Zerbini, E.Gebre-Wold, A.Demissie, D.[Effect of work and diet on body weight change, body condition and lactation performance of F1 crossbred cows used for draught]Effect of work and diet on body weight change, body condition and lactation performance of F1 crossbred cows used for draught
Autor: Zerbini, E.

This paper attempts to highlight the major components of an established regional research consortium in South Asia, the operational difficulties, and proposed improvements needed in implementing this regional research. The components and the lessons learned from this mode of research will be very...


Zerbini, E.[Existing and proposed ecoregional research in South Asia]Existing and proposed ecoregional research in South Asia

Twelve non-milking, non-cycling F1 crossbred dairy cows (Friesian x Boran and Simmental x Boran) in low body weight and body condition were stratified to 2 diets according to parity, body weight, body condition score and calving intervals to estimate time necessary to resume reproductive activity...


Zerbini, E.Gebre-Wold, A.Gemeda, T.Demissie, D.[Effect of supplementation of depleted, non-milking, non-cycling F1 crossbred cows on time of repletion and resumption of reproductive activity]Effect of supplementation of depleted, non-milking, non-cycling F1 crossbred cows on time of repletion and resumption of reproductive activity

This discussion which is based on output/input ratios includes many factors which are likely to be extremely important in relation to the overall utilization of feed by multipurpose cattle. It compares different output/input ratios (biological efficiencies) for draught work, beef production, milk...


Zerbini, E.Gebre-Wold, A.[Output/input ratios in single and multipurpose cattle]Output/input ratios in single and multipurpose cattle

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 ...


Zerbini, E.Asamenew, G.[Potential of cow traction in the Ethiopian highlands farming system]Potential of cow traction in the Ethiopian highlands farming system

Research on the effective utilization of animal power in small scale agriculture in Ethiopia, to sustain and enhance economic Development of the country, is essential. Draught animal power is the best alternative power source of the intermediate technology level because low wages and small farm s...


Zerbini, E.Gebre-Wold, A.[Prospects for animal traction research and development in Ethiopia]Prospects for animal traction research and development in Ethiopia

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...


Zerbini, E.Gebre-Wold, A.Shapiro, Barry I.[The potential of cow traction in the East African highlands]The potential of cow traction in the East African highlands

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...
