Celery (Apium graviolens L.) extraction as the inhibition of pathogenic microorganism in broiler

Abstract

Pathogenic bacteria in the digestible tract can inhibit the optimization of the feed absorption on broiler chicken. The research aimed to determine the ability of the inhibition of bioactive compounds on celery as pathogenic bacteria such as Salmonella, Escherichia coli, and Clostridium perfringens was found in broiler digestive tracts. The stages of the study were the determination of celery plants and inhibitory test on Salmonella, Escherichia coli and Clostridium perfringens with P0 concentration: Negative control (aquades), P1: Positive control (5 μg/ml amoxicillin), P2: 2,5 mg/ml celery extraction, P3: 5 mg/ml celery extract, and P4: 10 mg/ml celery extraction. Variables observed were the inhibition zone diameter using the disc method. The data obtained were tabulated with the Microsoft Excel program, then analyzed by a completely randomized design (CRD) where the significant differences analyzed used Duncan's analysis. Based on the results study showed that plant determination was celery (Apium graveolens, L.). The addition of celery extraction with a concentration of 10 mg/ml showed a higher inhibitory power compared to the use of antibiotics against Salmonella and E Coli bacteria.
