  • This research aimed to know the potential of sambiloto extract (A. paniculata Ness.) and meniran extract (P. niruri Linn.) as feed additives in feed increase hen day production of laying hens infected by Avian Pathogenic Escherichia coli (APEC). The experimental animals used were 20 of 32-week-old laying hens. P0(-) treatment was not given sambiloto extract and meniran extract and it was not infected by APEC, P0(+) treatment was infected by APEC bacteria in amount of 2 ml/head/IM, but it was not given sambiloto extract and meniran extract, P1 treatment was infected by APEC in amount of 2 ml/head/IM and it was given 10% sambiloto extract and 30% meniran extract in amount of 1 ml/head/oral, P2 treatment was infected by APEC bacteria in amount of 2 ml/head/IM and it was given 20% sambiloto extract and 20% meniran extract in amount of 1 ml/head/oral, P3 treatment was infected by APEC bacteria in amount of 2 ml/head/IM and it was given 30% sambiloto extract and meniran extract 10% in amount of 1 ml/head/oral. The study was conducted for three weeks. The chicken production was calculated everyday. The results were analyzed by Analysis of Variance (ANOVA) and followed by Duncan's Multiple Range Test (DMRT). the result of potential sambiloto extract and meniran extract that were infected by APEC bacteria increased the hen day production (p <0.05).
