Comparison of the Effect of Different Levels of Garlic Powder on the Levels of Serum Cholesterol and Triglyceride of Two Strains Broiler Chicks (Arian and Ross)

Background and Objectives Garlic [Allium sativum] has been used as a medicinal plant for thousands of years. Epidemiologic studies show an inverse correlation between garlic consumption and progression of cardiovascular disease. Cardiovascular disease is a complex and multifaceted disease and is characterized by several factors such as elevated serum lipids (cholesterol and triglyceride). In this study we will investigate the effect of different levels of garlic powder on serum cholesterol and triglyceride of two strains of broiler chicks. Methods Utilizing a completely random design with factorial method 714 one-day old broiler chicks of two different strains (Ross and Arian) were put on seven different diet regiments for a period of 8 weeks with 3 daily feedings. The chicks in the control group were exclusively put on basal diet and the other groups were fed with o.1 0.2 0.4 0.6 0.8 and 1% of garlic powder in the basal diet. After 8 weeks blood sample was collected from the chicks. The level of serum cholesterol and triglyceride of collected blood samples were measured. The collected data was analyzed using Univariate Analysis of Variance followed by Tukey post hoc test. P< 0.05 was considered significant. Results Garlic powder reduced the level of serum cholesterol significantly (p
