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 dayoldbroiler chicks of CP 707 strains were divided into five groups for five treatments. A CompletelyRandomized Design was used in this experiment. The treatments were 0 (control), 2, 4, 6 and 8% fishfermented by LAB substitution of basal diet containing 8% fish meal. The parameters were blood lipidprofile 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 byDuncan’s Multiple Range test. Results showed that using fish silage fermented by LAB on broiler’s feeddid not affect total cholesterol and HDL cholesterol, but significantly affect (p<0.05) levels of LDLcholesterol and serum triglycerides of broilers. Based on serum lipid profile, it could be concluded thatfish fermented by LAB can be used as a substitute for the 100% fish meal in broiler’s feed.

Abstract

Glucomannan is consisted of D-glucose and D-mannose with β-1.4 linkages. Poultry had no enzyme to digest β linkage so that porang (Amorphophallus onchophyllus) glucomannan could be a prebiotic candidate. The study purposed to determine the effect of porang glucomannan on caecum bacterial composition (similarity, diversity, grouping of bacteria) using Terminal Restriction Fragment Length Polymorphisms method and performance (body weight gain, feed intake, feed conversion ratio) of broiler chickens. One hundred and eighty unsexed day old chicks (DOC) were divided into 6 treat-ments and 3 replicates (10 birds each) using completely randomized design (CRD). The treatments were P0 (basal feed), P1 (basal feed + 0.05% porang glucomannan), P2 (basal feed + 0.1% porang glu-comannan), P3 (basal feed + 0.15% porang glucomannan), KJ (basal feed + 0.1% commercial konjac glucomannan), and KM (commercial feed). The results showed that caecal bacterial composition of porang glucomannan treatment had similarity with konjac glucomannan and basal feed. Diversity index and species number of porang glucomannan treatment was higher than konjac glucomannan. Gluco-mannan prebiotics had higher Lactobacillus while the lowest Clostridium was obtained in 0.1% porang glucomannan treatment. The inclusion of glucomannan prebiotics gave no negative effect on the per-formance of broilers.
