Forty five, day-old broiler chicks were randomly allocated to three dietary treatments for a period of eight weeks. Control (group I) were given 0% garlic. Treatment groups (Π and Ш) were given garlic powder at 1.5% and 3% respectively in feed on dry matter basis. There were no significant differences in the average final live weights of birds on the different treatments. However, birds on garlic treatments (1.5% and 3%) had slightly better average feed intake, weight gain and average body weight than those on the control diet. No decline in Hb concentration and totalerythrocyte count of birds fed garlic (group Π and Ш) was observed. Similarly, total white blood cells (heterophils and lymphocytes) did not change significantly for birds on garlic treatments when compared to those on the control diet. Plasma glucose, total cholesterol, VLDL-C, LDL-C and triglycerides were significantly (P≤0.05) decreased by the dietary supplementation of garlic in group Π and Ш than those on the control diet. However, there was significant (P≤0.05) increase in plasma HDL-C in garlic supplemented groups (Π and Ш) than those on the control diet. Along with, there was significant (P≤0.05) decrease in alanine and aspartate transaminase enzymes in plasma of garlic supplemented groups (Π and Ш) than those on the control diet. There were no significant differences in the total plasma proteins, uric acid, tri-iodo thyronine (T3) and thyroxine (T4) in plasma of garlic supplemented groups (Π and Ш) than those on the control diet. Thus, the study revealed that feeding garlic upto eight weeks slightly promote the growth of broiler chickens along with improved weight gain and feed conversion efficiency/ratio. Insignificant decreases in red blood cells and haemoglobin revealed the haemolytic activity of the garlic supplement. The marked effect on the plasma glucose, lipid profile and alanine and aspartate transaminase enzymes indicate the role of garlic on lipid and carbohydrate metabolism. Garlic supplementation failed to influence the plasma protein and thyroid hormone levels. This indicates no effect of garlic on protein metabolism. In conclusion, 1.5% garlic supplementation in feed in broiler chickens is effective in regulation of carbohydrate and lipid metabolism with improvement growth.enThesis
