The effect of Noni (Morinda citrifolia) leaf shoot meal as an antioxidant and antibacterial against Salmonella sp. and Escherichia coli

Indonesia as a tropical country is rich in biological resources, among which are known as herbal plants. One of the herbs that are often used is Noni ( Morinda citrifolia ), which has been reported to possess antioxidant and antimicrobial activities. The objective of this study was to evaluate the antioxidant and antibacterial effects of Noni Leaf Shoot Meal (NLSM) to inhibit Salmonella sp. and Escherichia coli as poultry ration. Two hundred and forty kampong chickens of 4 weeks old were reared until 12 weeks old. The diet treatments were R0= 0% NLSM (control), R1= 0.5% NLSM, R2= 1% NLSM, R3= 1.5% NLSM, R4= 2% NLSM, and R5= 2.5% NLSM. Six treatments and four replications are used with ten kampung chickens per replicate. Data were analyzed using descriptive statistics. The parameters measured were phytochemical analysis, vitamin A, beta carotene, Malondialdehida (MDA) blood, inhibition zone diameter, and Clearance test. Results showed that NLSM could reduce MDA blood and bacterial concentration. It is concluded that lower MDA concentration in kampong chicken blood indicates that NLSM contains high antioxidants. NLSM can reduced bacterial concentration in chicken blood so it can be used as a natural antibacterial to improve kampong chickens production and immune system.
