The effect of probiotic supplemented ration on broiler abdominal fatty content and final weight.

In this research we were studying the effect of ration supplemented with Lactobacillus bulgaricus and Streptococcus 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 – 1.25% Lactobacillus bulgaricus and Streptococcus thermophilus, R3 – 2.0% Lactobacillus bulgaricus and Streptococcus thermophilus; which was five times repeated. Result indicated that ration supplemented with 1.25% Lactobacillus bulgaricus and Streptococcus thermophilus has highest final weight and suplemented with 2% has the lowest abdominal fat content.
