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/...

Effect of work and diet on body weight change, body condition and lactation performance of F1 crossbred cows used for draught
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...

Forty F1 crossbred dairy cows, 20 Friesian x Boran and 20 Simmental x Boran, in a 2 x 2 factorial arrangement (non working-non supplemented, non working-supplemented, working-non supplemented, and working-supplemented) were used to study the effect of work and diet supplementation on roughage int...

Effect of work and diet on dry matter intake, feed digestibility and nitrogen balance of F1 crossbred cows used for draught
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...

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...
