N2  - This experiment was carried out to investigate the effect of partial or complete (50 and 100%) replacement of dietary corn by dried sugar beet pulp(DSDP) on milk yield of ewes and average daily gain of suckling lambs during suckling period. In this experiment, fifty four late pregnancy local Egyptian ewes were randomly divided to three diets groups' (18 in each) and yield of lambs for each group (I control, n 50% DSDP and ill 100% DSDP). Three experimental diets were formulated to given to ewes from the beginning of the last month of pregnancy to the end of weaning lambs (14 weeks). The amount of three diets were offered during the last month of pregnancy at the rate of 1 kg/ewe/day and from parturition to weaning their lambs (14 weeks) was at the rate of 1.15 kg/ewe/day. Rice straw was added during the experimental period ad libitum. The starter diets were given ad libitum to lambs from day 5 until weaning as creep feeding together maternal milk. The results showed that daily milk yield was slightly increased in ewes given DSDP diets as compared with the control diet. The average daily yield was 448, 495 and 521 g for ewes given control, 50% DSDP and 100% DSDP diets, respectively. The discrepancies were statistically insignificant. This may lead us to conclude that DSDP is a good energy source as corn for milk production if it is not better. Milk constituents from total solids, ash, fat, protein,lactose, Ca, P and Mg were not significantly altered by replacing dietary corn by DSDP. In similar experiments it has been reported that fat corrected milk was not affected or slightly increased by DSDP incorporation. Male and female lambs growth rates were followed-up from birth to weaning the lambs. The data illustrates that suckling period extended for 100 days when the lambs reached 24.5 to 28.11 kg body weight by the end of this stage. The averages daily body weight gains of male lambs were 222.8, 240.9 and 229.1 g. The corresponding values for female lambs were 215.6, 223.4 and 200.9 g. with control, 50% and 100% DSDP rations, respectively. Although statistical analysis did not show any significant difference between means due to dietary treatments, the daily gains of lambs given 50% DSDP ration surpassed those given the control or 100% DSDP starters
