ANALISIS USAHA PENGARUH EKSTRAK MENIRAN (Phyllanthus niruri Linn.) SEBAGAI PENGGANTI Antibiotic Growth Promoter (AGP) PADA AYAM PETELUR YANG DIINFEKSI APEC (Avian Pathogenic Escherichia coli) PENELITIAN EKSPERIMENTAL

The effect of meniran extract (Phyllanthus niruri Linn.) addition as a substitute for AGP in the laying hens feed, on the business analysis of farming laying hens infected and those not infected with Eschericia coli. 50 laying hens were randomized into two experimental factors with five treatments, each treatment consisting of five replications. Laying hens were infected with E. coli bacteria intramuscularly with a concentration of 108 cells/kg body weight as much as 1 ml and then the clinical symptoms were observed for 3 days. The laying hens began to be treated with P0-, P0 +, P1, P2 and P3 and maintained for 3 weeks. The experimental data obtained were analyzed statistically using two way analysis of variance (ANOVA). The results showed that the addition of meniran extract (Phyllanthus niruri Linn.) as the Antibiotic Growth Promoter in the chicken feed had no effect on the business analysis on the laying hen feed infected with E. coli, where the addition of 20% and 30% of meniran extract in the laying hen feed was effective in subtituting the AGP for those hen infected and not infected E. coli and it showed the most profitable business analysis with the best BEP price and R/C ratio
