Abstract

This study briefly summarized the role of ginseng in real amelioration of the growth performance and some haemato-biochemical alterations adverse effects caused by lead in growing lambs. 20 lambs, 4-6 month old, at Sharkia Governorate 10 clinically healthy with 20-22 kg B.Wt., grazing in area faraway main highways and other 10 lambs grazing near main highways with 13-15 kg B.Wt. Lambs were divided into 4 equal groups n=5 /group. 1st group grazed in area faraway main highways healthy control, 2nd group grazed in area faraway main highways and received a daily 200 mg ginseng extract/lamb orally for 30 successive days. 3rd group lambs grazed near main highways left without treatment. 4thgroup lambs grazed near main highways and received 200 mg ginseng extract/lamb same like group 2. Two blood samples were collected from all lambs at 1st day and 15th day post treatment for haemato-biochemical analysis.Clinical signs appeared on lambs grazed near main highways due to excess serum lead concentration inhaled from environment. 2nd group lambs showed significant increase in weight gain, total erythrocytic count, total leukocytic count, hemoglobin content, packed cell volume, total protein, iron, copper as compared to control group. Lambs grazed near main highways showed a significant decrease in live body weight, weight gain, erythrocytic count, hemoglobin content, packed cell volume, total leukocytic count, serum total protein, copper and significant increase in feed conversion rate, serum lead, iron, AST, ALT, alkaline phosphatase and urea,T3,T4 as compared to control group. Lambs of the 4th group showed improvements in body weight gain, feed conversion rate, erythrocytic count, leukocytic count, hemoglobin content, packed cell volume, total protein, AST, ALT, alkaline phosphatase, urea and creatinine. It could be concluded that lead induced many alterations in growth performance and haemato-biochemical parameters in lambs and that could be overcome by daily administration of ginseng.
