The influence of using fish fermented by lactic acid bacteria as feed substitution on serum lipid profile of broilers

Abstract

The study was aimed to examine the effect of the use of fish fermented by lactic acid bacteria (LAB) as a subtitution for fish meal on serum lipid profile of broiler. One hundred and twenty five dayold broiler chicks of CP 707 strains were divided into five groups for five treatments. A Completely Randomized Design was used in this experiment. The treatments were 0 (control), 2, 4, 6 and 8% fish fermented by LAB substitution of basal diet containing 8% fish meal. The parameters were blood lipid profile including total cholesterol, Low Density Lipoprotein (LDL) and High Density Lipoprotein (HDL) cholesterol and triglycerides. Data was analyzed by one-way Analysis of Variance (ANOVA). When the F test indicated a significant effect, the differences between the mean values were analyzed by Duncan's Multiple Range test. Results showed that using fish silage fermented by LAB on broiler's feed did not affect total cholesterol and HDL cholesterol, but significantly affect (p<0.05) levels of LDL cholesterol and serum triglycerides of broilers. Based on serum lipid profile, it could be concluded that fish fermented by LAB can be used as a substitute for the 100% fish meal in broiler's feed.
