Effects of Fermented Milk and Soybean with Probiotic on Blood Lipid in Rats

Abstract

Probiotics have several positive benefits such as reducing pathogenic bacteria population to help food digestion and lowering blood lipid levels. Therefore, a study was conducted to evaluate the effect of fermented cow milk, soybean milk, and combination of both with probiotic bacteria on HDL, LDL, and blood cholesterol level of rats. A total of 30 rats,8 weeks old were used in this study in a Complete Randomized Design. The rats were randomly assigned into 5 treatment and replicated 5 times of 1 rat each. The rats in first group (P0) were given basal feed without probiotic, P1 = basal feed + fermented cow milk; P2=basal feed +75% fermented milk + 25% soybean milk; P3 = basal feed + 50% fermented cow milk + 50 % fermented soybean milk P4=basal feed + fermented cow's milk with different bacteria. There was a non-significant reduction in LDL, and cholesterol level of rats, also non-significant addition in HDL due to probiotic supplementation and the highest reduction is in group fed P4. Addition of probiotic in diet of rats gave the same respond, but have beneficial effect in improving blood cholesterol although non-significant different
