Abstract
The aim of study effecting fixed factors (breed, year of birth, age of dam, sex of lambs) in total milk yield and milk composition and some of growth traits (birth weight and weaning weight), the overall mean of milk yield (66.58 ±1.67. kg) ,it was breed effect significant (P<0.05) , while the effect factors (birth year, age of the ewe, sex of lambs, type of birth) was not significant, , the overall mean of milk components (fat, lactose, protein, non-fat solids) was 4.18 ± 0.29, 4.42 ± 0.02, 5.47 ± 0.11 and 10.69 ± 0.14 %, respectively ,the factors are non- significant effect on milk composition, the overall mean of birth weight was 4.76 ± 0.06 kg, the breed, year of birth, age of the ewe and the sex lambs did not effect on it, weight at weaning was 19.77 ± 0.27 kg. The effect of breed was highly significant, as the Turkish Awassi breed advantage to the local, while the factors (year of birth, age of ewe, sex of lambs) were non- significant effect on weaning weight. We conclude the local Awassi was superior to the Turkish in total milk yield. The birth weight of Turkish Awassi was slightly higher on the local, but dominant was highly significant in weaning weight.
