Abstract
In this research we were studying the effect of ration supplemented with Lactobacillus bulgaricus and Streptococus thermophilus on broiler abdominal fatty content and final weight, using Completely Randomized Design (CRD) with four treatments: R0:0% Lactobacillus bulgaricus and Streptococcus thermophilus as control, R1: 0.5% Lactobacillus bulgaricus and Streptococcus thermophilus; R2: 1.5% Lactobacillus bulgaricus and Streptococcus thermophilus; R3: 2% Lactobacillus bulgaricus and Streptococcus thermophilus, which was five times repeated. Result indicated that ration supplemented with 1.5% Lactobacillus bulgaricus and Streptococcus thermophilus has highest final weight but the lowest abdominal fatty content.

Key words: probiotic, Lactobacillus bulgaricus, Streptococcus thermophilus, abdominal fatty, final weight
