ABSTRACT
A total of 900 TDMY of 271 Awassi ewes belonging to five commercial flocks in three
governorates ( Baghdad, Diala and Mosul ) were used to evaluate ewes for this trait. Milk was
recorded at a monthly interval starting 14-21 days post-lambing till the ewes were dried off. On
the day of test , the lambs were separated from their mothers at 8.00p.m. On the following
morning, ewes were hand milked at 8.00 a.m., and the quantity of milk was recorded.
The overall mean of TDMY was 0.625 kg, and the repeatability estimate was 0.65. The
effects of flock, age of ewe, type of birth, stage of lactation, month of test and lambing season
were significant.
