The  experiment was designed to study the effect of the use of two levels (1 and 2%) of  leaves of moringa, rosemary or olive plant on the performance of ducks compared to  the control diet or the control with antibiotic. The most important results could be summarized as follows: a significant  improvement was found in the digestion coefficients of dry matter, crude protein,  crude fiber and nitrogen free extract, for all treatments containing plant additives  compared with the antibiotic and control groups. All groups fed on diets containing  phytogenic feed additives or antibiotic showed a significant decrease in the amount  of feed consumed with a significant improvement in the feed conversion ratio compared with the control group. The best feed conversion ratio was for the group  fed on a diet with 2% of moringa leaves. The weight of the carcass was highest for  the groups fed on plant additives compared to the antibiotic and control group,  whereas the weight of the liver, the weight of the digestive system and the length of  the digestive tract (cm) were significantly lower for the antibiotic and control  groups. Nutrient groups on plant or antibiotic additives showed no significant effect  on% moisture content and% crude protein for ducks, but significantly increased  meat content of ash  aIssued also as CD 4aMoringa leaves  4aOlives leaves  4aRosemary leaves 0 aMamdouh Omar Abdelsamee , eSupervisor0 aMohamed Reda Mohamed Ibrahim , eSupervisor0 aMona Mohammed Aly Hassan , eSupervisor  uhttp://172.23.153.220/th.pdf
