الملخص EN

This study was carried out at sheep section-Shami Camels Research Station, Al-Ghazlaniyeh District, Damascus countryside, Syria during year 2017 on twenty-seven lactating Awassi ewes homogenous.

To determine the effect of adding of emotic in pregnant Awassi ewes ration in some productive indicators.

The ewes were divided into three groups: The first group was control (without emotic), the second and the third group were fed on basic ration with adding 3,6g of emotic respectively, along gestation period.

The experiment was designed according to the complete randomized sectors.

Adding of emotic to ration led to improve the weight of the daily increase and increase in the daily amount of milk and composition of milk.

And recorded the highest increase in the daily increase for birth weight at treatment 6g and reached 242.44g comparison with the control and 3g treatment (226.83, 236.72)g respectively.

The results showed that increased of milk amount and the 3g treatment was the most affected, as it increased the milk amount in the end 53.85% from the beginning of the experiment comparison of the control and 6g treatment who have increased their percentage (21.05, 32.91) % respectively.

Also that using of emotic led to increased of the total amount of solids and these was the best value after month of birth at adding 6g (11.48)g comparison with the Control and 3g treatment (10.43, 11.16)g respectively.

The values of total protein were increased until a month after birth then begin to drop and the higher value was recorded in the treatment 6g (5.79)g comparison with (5.16)g at control and (5.43)g at 3g treatment.

The value of milk sugar reached its peak after tow months from the birth in 6g treatment (4.90)g comparison with the control and 3g treatment (4.67, 4.84)g respectively.

There were not effect in the amount of fat with adding emotic.

And not effect in the weight, but the higher increased at concentration 3g before birth and the increase rate (17.87%) comparison with the beginning.

It was showed adding 6g/day/ewe has a general positive effect.
