Cardio-respiratory and mechanical work output variables were measured for four F1 crossbred dairy cows (average weight 475 kg) over a range of work levels. Resting (standing prior to exercise) heart rates (average 62 beats per min) and respiratory rates (average 21 breaths per min) were similar t...

Relationships between cardio-respiratory parameters and draught work output in F1 crossbred dairy cows under field conditions
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...

Effect of work on dry matter intake, milk production and reproduction of multipurpose cows fed low quality roughage
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...
