Journal Article 1995

Autor: Gemeda, T. Zerbini, E. Gebre-Wold, A. Demissie, D.

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...

Journal Article 1996

Autor: Zerbini, E. Gebre-Wold, A. Demissie, D.

Eighteen F1 crossbred dairy cows (Friesian X Boran and Simmental X Boran) were allocated to one of three diet groups (H: natural pasture hay; H + 3: natural pasture hay + 3 kg concentrate; and H + 5: natural pasture hay + 5 kg concentrate) using a stratified random sampling procedure, with parity...

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...

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...

Based on the promising results obtained from on-station, the cow traction study was further taken to on-farm for verification under the Ethiopian smallholder farmers management conditions. The study was undertaken in Holetta area between 1992 and 1996 by involving 14 farmers. Mean dairy milk yiel...

The results of the research showed that hay intake was 10 percent greater in working compared to non working cows. Cows responded to underfeeding by a progressive adaptation until a new equilibrium between dietary supply and requirements was reached. However, in draught cows fed low quality rough...

The study investigated the effect of work on the postpartum estrous cycle length and ovarian activity of crossbred dairy cows used for draught. Sixteen dairy cows were assigned to two dietary feeding regimes (i.e. diet 1=9 MJ ME/kg DM; diet 2=10 MJ/kg DM). The cows in both diets started to work a...

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...
