Abstract

This experimental work was carried out in the research unit of the Department of animal production، Faculty of Agriculture Omar Al-Mukhtar University. In order to know the effect of levels of Artemisia powder on productive performance and some characteristics of carcass in broiler chicken breed Ross، between 14-45 days of age.45 birds were used، which were divided into three treatments، The first treatment was fed on a commercial diet to which in other treatments، 4gand5g of Artemisia powder were added respectively and each treatment was divided into three replicates. Each replicate contained Five birds. The results were recorded as follows a significant increase P<0.001 was recorded in the final weight where the treatment of 5 g Artemisia was significantly superior to that of the control treatment، and the treatment 5 g Artemisia was superior to the treatment of the control and 4 g Artemisia in the daily weight gain and the total weight gain. It was also noted that the consumed feed recorded a significant P<0.005 superiority in 5g Artemisia treatment compared to the control treatment. There were also significant differences P<0.005 between the different treatments، and the best feed conversion factor was 1.39 gm in the control treatment، compared to adding 4 gm artemisia، which recorded 1.45 gm، and 5 gm artemisia، which recorded 1.41 gm. The results showed that there were significant differences in weight before slaughter، weight after slaughter، weight without viscera(g) and breast weight where 5g Artemisia treatment was superior to the control and treatment 4g Artemisia. The results also concluded that the weight of the liver had increased significantly in the treatment 5g Artemisia compared to the treatment of the control، while the control treatment was superior to the rest treatments in the weight of the spleen. It was also found that the treatment of 4g Artemisia recorded a significant increase in the length of the intestinein cm where was recorded 222.15cm compared to the treatment of the control and treatment 5gArtemisia which were recorded 218.85cm،217.35 respectively.
