This experiment was conducted to investigate the effects of dietary garlic powder(GP) on growth performance and mRNA expression of hepatic 3-hydroxy-3-methylglutaryl-CoA reductase(HMG-CoA reductase) in broiler chickens. Day-old male chicks (Ross, n=270) were fed diets containing 0%[positive control(PC) with antibiotics or negative control(NC) without antibiotics], 1%, 3% and 5% GP for 6 wks. There were no significant differences in feed intake among the treatments throughout the experimental period. Body weight gains in groups fed dietary GP at 3% and 5% were significantly higher than that of NC group (P<0.05). Feeding GP up to 5% did not exert any adverse effect on weight gain and feed intake. There were no significant differences in the relative weights of liver, spleen, cecum and breast muscle. The content of meat cholesterol in GP containing dietary groups tended to be reduced as compared to NC group. Average infectious bronchitis antibody titers in chicks fed GP containing diets were significantly higher than that of NC group(P<0.05). The mRNA expression of hepatic HMG-CoA reductase was reduced by dietary GP. These results indicate that dietary GP has growth promoting effects and tended to alter cholesterol metabolism in broiler chickens.
