0.01) the total milk yield. The differences were however not significant when feeding Zaraibi does with a high energy level. The overall results showed that the NRC (1981) energy standards could be satisfactorily practised with lactating Zaraibi does as a low productive breed. Increasing these standards by 25 % could only be achieved in Damascus does which possess a high milk production potential. A high energy intake did not affect the milk constituents except protein. It was only increased (P

The protein percent was 2.51 and 2.76, respectively with low and high energy diets in Zaraibi does, while it was 3.04 and 2.93 respectively in Damascus does. The milk protein content of Damascus does was higher than that of Zaraibi does. A high milk protein content in milk has a technical importance for milk processing.
