Abstract

This research aimed to determine the effectiveness of the addition of probiotics based on local microorganisms (MOL) of cattle's rumen and chicken intestines in feed as a substitute for Antibiotic Growth Promotor (AGP). 200 day old chicks were used in this research. The method used the Completely Randomized Design with four tratments and five replications, such as P0 (without probiotics), P1 ( (Feed + probiotics with a dose of 5 ml/Kg), P2 (Feed + probiotics at a dose of 10 ml/Kg), P3 (Feed + probiotics at a dose of 15 ml/Kg). The parameters of this research are performance and carcass quality. The results of microbiological analysis showed that probiotics based on MOL contained a concentration of Bifidobacterium 3.5 x 107 cfu / ml, Bacillus 0.9 x 106 cfu/ml, Streptococcus 1.06 x 106 cfu/ml, and Lactobacillus 12.5 x 107 cfu/ml. The research showed that the adding of Probiotic was not significant (P>0.05) on feed intake, body weight gain, and carcass percentage but significantly (P>0.05) on mortality and Feed Conversion Ratio. Treatment without probiotic has a higher mortality (8%) than with probiotics (0,67%). The Feed Conversion Ratio by given probiotics 5 ml and 10 ml/kg feed was lower than treatment without probiotics.
