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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
