The effects of coconut flour on blood lipid parameters in male domestic rabbits (Oryctolagus cuniculus L., 1758) were examined. Four to seven week-old rabbits (n = 28) were fed with different diets for 6 weeks. Seven animals were randomly assigned to each treatment group: Treatment 1= 2, 600 kcal/kg of feed without coconut flour (A); treatment 2 = 2,600 kcal/kg of feed with coconut flour (B); treatment 3 = 2,900 kcal/kg of feed without coconut flour (C) and treatment 4 = 2,900 kcal/kg of feed with coconut flour (D). At the start of the study, pretreatment blood serum lipid (total cholesterol, HDL and LDL cholesterol and triacylglycerol) concentrations of the rabbits in the four treatment groups were not significantly different. By the end of week 6, fasting serum triacyl glycerol concentrations significantly decreased (P
