Abstract
Current study was conducted on 15 Awassi lambs with an average Weight11.24±0.06kg and with average age (1 month aged) Lambs were randomly divided into three groups,(5lambs/group) 1stgroup: control, 2nd group was injected subcutaneously once every ten days with Iron and vitamin B12 (4.54mg/kg body weight and 4.54μg/kg body weight ) 3rd group lambs wereinjected subcutaneously with Iron and vitamin B12(9.09 mg /kg body weight and 9.09μg/kg body weight ) respectively. Results showed a significant increase(P≤0.05)in final weight, total gain, daily gain, body length, chest girth,fore thickness, lymphocyte % and monocyte% intreated groups with Iron and vitamin B12 compared with control group. Also results shows a significant increase(P≤0.05)for 2nd group lambs compared with control in fore height, rear height and rear thick. While there area significant decreaseIn treated groups in neutrophils % and stress index.In conclusion, iron and vitamin B12 injection to weaning lambs improve body measurements and weight and immunity
