Abstract
The purpose of this study is to evaluate the potency of several local phytogenic (Vernonia amygdalina Del., Calotropis gigantean, Syzygium oleana, Syzygium cumini, L) as antioxidant and antimicrobial sources in feed additives for non-ruminant animals. Antibiotic as feed additive has been banned since 2006 due to harmful effect of antibiotic not only for animals but for consumers. Phytogenic as suitable natural alternatives has been intensively studied and had positively effect on animal health and productivity. Five extract phytogenic that massively grow in Aceh were extracted by using maceration method with the comparison of material and ethanol solvent 1:4. Antioxidant testing by using DPPH method and antimicrobial pathogen testing (Salmonella and E. coli) by using Kirby-Bauer disk diffusion method with gradient doses of extract (250 mg/mL, 500 mg/mL, 750 mg/mL), chloramphenicol as positive control and aquadest as negative control. The results of study indicated that Syzygium cumini, was the best phytogenic feed additives compared with the others feed additives. Syzygium cumini, L had antioxidant activity (IC50 19.91) and inhibition zone diameter of 4.80 and 12.78 for E.coli and Salmonella respectively with the dose of 750 mg/mL. In conclusion, all phytogenic feed additives can be utilized as feed additives for non-ruminant animals with S. cumini, L as the best phytogenic feed additives.
