Background and Objective: Cholesterol plays important roles in membrane structure and as a precursor for the synthesis of the steroid hormones. However, abnormal deposition of cholesterol and cholesterol-rich lipoproteins in the coronary arteries could lead to atherosclerosis. This study was carried out to assess the efficacy of raw and sun-dried garlic on growth performance, immunity and cholesterol contents of broiler chickens. Materials and Methods: The efficacy of raw and sun-dried garlic as growth promoter, immune booster and cholesterol-lowering agent on broiler chickens was investigated in a 56 days feeding trial. Locally produced garlic bulbs were purchased from a commercial market in Northern Nigeria and ground with the husk into a paste. A portion of the paste was thinly spread on a clean mat and sun-dried for 2 days. The dried substance was ground to obtain dried garlic powder. The garlic paste and garlic powder were incorporated into broiler starter and finisher diets at 0, 1, 2 and 3% levels. The raw garlic was also included at 1, 2 and 3% levels (the inclusion level was calculated to exclude moisture content). Two hundred and ninety-four Anak 1 day old broiler chicks were randomly distributed into 7 dietary treatments of 21 birds each in a completely randomized design. Data were subjected to two-way analysis of variance using SPSS and the means were analysed using Duncans multiple range test at statistical significance was p<0.05. The white and red blood cells counts were determined using haemacytometer method. The packed cell volume and haemoglobin were measured by the methods of Wintrobe-micro-haematocrit and cyanomethaemoglobin, respectively. The serum samples were analyzed for total cholesterol, triglycerides and high-density lipoprotein cholesterol using Randox kit. Results: Raw and sun-dried garlic at 1, 2 and 3% did not influence growth performance and haematological parameters of broiler chickens but reduced the total cholesterol, liver cholesterol, triglycerides, abdominal fat pad and low-density lipoprotein cholesterol contents of the animals. Conclusion: The raw and sun-dried garlic at the inclusion levels reduced total cholesterol, liver cholesterol, triglycerides, abdominal fat pad and low-density lipoprotein cholesterol contents in the experimental animals while they improved high-density lipoprotein cholesterol.
