  Antibacterial activity limonoid compounds of three different solvent extracts (methanol, ethyl acetate and n-heksane) prepared by soxhlet extractor from orange waste juice were screened against two pathogenic bacteria Escherichia coli and Salmonella enteridis. The highest antibacterial potentiality was exhibited by the limonoid-ethyl acetate followed by the (limonoid-methanol) and (limonoid-n-hexane).The orange waste juice extract can be considered to be as equally potent as the antibiotics. The zone of inhibition, Minimum Inhibitory Concentration (MIC) of the orange waste juice extracts showed that limonoids extracted with ethyl acetate (limonoids-ethyl acetate) resulted in better inhibition of limonoids extracted with (limonoids-methanol) and (limonoids-n-hexane). The concentration 250 ppm of MIC were test showed inhibition of (limonoids-ethyl acetate) higher with a percentage minimum (44.15 for the bacterium Escherichia coli and 14.69 for the salmonella enteridis) than (limonoids-methanol) (10.67 and 3.84) and (limonoids-n-hexane) (35.58 and 14.10). In vitro antibacterial screening of crude (limonoid-ethyl acetate) (limonoid-methanol) and (limonoid-n-hexane) of methanol extract of orange juice waste with concentration 250 ppm were test showed the clear zone in millimeters (11.75 for the bacterium Escherichia coli and 10.25 for the salmonella enteridis) than limonoid-methanol (8.00 and 9.00) and limonoid-n-hexane (8.00 and 9.25). However, when compared to synthetic antibiotics (neomiditril and coleridin), the clear zone of limonoids lower (24%) but still showed his ability as an anti-microbial. (Limonoids-ethyl acetate) dose of 250 ppm showed better activity than doses of (limonoid-methanol) and (limonoid-n-heksana) for the bacterium Escherichia coli to salmonella enteridis bacterial at 11.918 and 9.158. From these results we can conclude (limonoids-ethyl acetate) extract better than (limonoids-methanol) and (limonoids-n-hexane) and can be used as a substitute for anti biotic synthetic antimicrobial. The phytochemical analysis of orange waste juice extracts showed presence of triter penes, alkaloid, flavonoids, steroid, phenolic, saponin.

  This study was conducted to evaluate the effect of orange (Citrus sinensis) waste juice extracts (OWJE) on performance in broilers chickens. A total of two hundred and forty unsexed broiler chicks (Arbor Acres CP-707) were randomly allocated to six treatments groups given varying concentrations of OWJE in the drinking water for 35 d. 0, 250, 500, 750 and 1000 ppm OWJE: water supplemented with an antibiotic only was used as a control. The growth responses achieved by broilers from all groups complied with standards. However, supplementation with 1000 ppm OWJE in drinking water increased feed intake and body weight gain, thereby increasing the feed conversion ratio of both starter (days 1-21) and finisher (days 22-35) broilers, while 750 ppm OWJE promoted feed intake and weight gain in starters. These results indicate OWJE is a useful additive for promoting broilers chicken growth. Additional research is needed to improve the suitability of OWJE as a feed additive which promotes growth in poultry.
