Potensi Penambahan Bakteri Asam Laktat Lactobacillus casei dan Lactobacillus rhamnosus Terhadap Konsumsi Pakan dan Konversi Pakan Ayam Pedaging

The aim of this research to determine the potential of lactic acid bacteria combined Lactobacillus casei and Lactobacillus rhamnosus in the feed to the level of feed consumption and feed conversion ratio of broilers. This study uses three treatments with six replications. P0 were the control group, broiler feed without the addition of lactic acid bacteria combined Lactobacillus casei and Lactobacillus rhamnosus, P1 treatment group were feed with the addition of lactic acid bacteria 0.25% Lactobacillus casei and 0.25% Lactobacillus rhamnosus, group P2 treatment feed with the addition of lactic acid bacteria 0.5% Lactobacillus casei and 0.5% Lactobacillus rhamnosus. Data were analyzed by Analysis of Variant (ANOVA) if there is a significant different then proceed with Duncan s multiple range test significance level of 5%. Feed consumption study results indicate there is a significant diferent (p <0.05) in the group of P1 and P2 when compared with controls (P0). The addition of 0.5% Lactobacillus casei and Lactobacillus rhamnosus 0.5% in the feed showed effective results on feed conversion of broiler.
