Moringa oleifera is a fast growing well-known cultivated species of plant belonging to the family Moringaceae, genus Moringa, common name of Moringa oleifera (MO) is (also known as “drumstick”) horseradish and ben oil tree. Moringa products have a wide range of applications in agricultural, nutritional, industrial and pharmaceutical processes. Moringa leaves have a relatively high crude protein content which varies from 25% to 32%. A high proportion of this protein ,amino acids is potentially available for digestion due to a high proportion of pepsin soluble nitrogen (82-91 %) and low proportion (1-2%) of acid detergent insoluble protein. chemical composition was evaluated in Moringa Leaves then Five iso-nitrogenous and iso-caloric experimental broiler diets were formulated as MOL0%, MOL5%, MOL10%, MOL15% and MOL20%, chemical analysis of lipid profile(triglycerides, total cholesterol, HDL, LDL and vLDL), and haematological analysis(Hb, RBC, PCV, MCV, MCHC, Plt, MPV, PCT, PDW, WBC, LYM) were recorded. There was a high correlation between body weight and some blood parameters of the broiler chicken. Age and body weight effect on blood parameters PCV, WBC, RBC, Hb, MCV and MCH. Decrease in the triglycerides level, plasma cholesterol, blood glucose, platelets count, plasma proteins and albumin. There was a significant increase in the body weight. White blood cells (WBCs) and packed cell volume (PCV) increased significantly, but the changes in Red blood cells (RBCs), hemoglobin level. The seed extracts of moringa are rich in polyunsaturated fatty acid. M. oleifera is an antibiotic that can improve the performance and health status, blood chemistry, increase cholesterol level (HDL, and decrease LDL, VLDL) of chickens.
