Abstract
Twenty four(12 male and 12 female) Awassi lambs aged (3.5-4 months) with average weights 22.75±0.34 Kg. ,were assigned into three main groups (8 lambs / group),each main group was divided into two sub groups(4 male or 4female/group) according to their live body weight.All groups of animals were fed on iso-nitrogen and iso-caloric diets, the 1st group was fed on ration without ground Ginger(control ration),while 2nd and 3rd group were fed on standard ration contained either 15 or 30 g.ground ginger/Kg.dry matter, respectively, for four months. Results indicat-ed that average daily gain, total gain, final weight, different body dimensions, red and white cell count, hemoglobin , packed cell volume, lymphocyte and netrophil cell percentages, total protein, globulin AST and ALP were increased significantly (P≤0.05), while the percentage of acidophil and netrophils cells, glucose and ALT were decreased significantly (P≤0.05) in blood lambs fed 2nd and 3rd treatment that contained 15 and 30g.ground ginger roots /Kg.dry matter, respectively as compared to those fed 1st treatment (control ration).Also lamb sex and age had significantly (P≤0.05) effect some studied parameters. It was concluded that adding of ground ginger roots had improved some productive and physiological parameters.
