Pemberian Probiotik Untuk Menggantikan Antibiotik Sebagai Growth Promotor Terhadap Performa Ayam Broiler

Abstract

Antibiotics on commercial diet can be used as a growth promotor. However, usage of antibiotics can cause antibiotic residues that harmful to consumers. The objectives of this research were to determine the effect of probiotics in the last week of maintenance to replace antibiotics as growth promotor on the performance of broilers. Two hundreds DOC’s strain CP 707 was used in the study. This study used a completely randomized design (CRD) with four (4) treatments and 5 replications and 10 DOC each. The treatments were R1 = feed A (5 weeks), R2 = feed B (5 weeks), R3 = R1 replaced basal feed + probiotic (last 7 days), R4 = R2 replaced basal feed + probiotic (last 7 days).Variables observed in this research were feed intake, feed conversion, body weight, body weight gain and mortality. The conclusion of study is feeding probiotic does not effect on the performance of broiler and does not give better results than antibiotics but it produce healthier broiler and safe for being consumed.
