ABSTRACT
The present study was conducted to evaluate effect of Sauropus androgynus extract (SAE) on feces production, nitrogen and phosphor contents and microflora in feces of layers. Forty eight 40-week days layers (strain RIR) were distributed to 6 treatment groups. One group was fed diet without SAE (P0), and groups were fed diets plus hot-water-SAE at level of 9 g/kg (P1), diets plus ethanol-SAE at level of 0,9 g/kg (P2), diets plus ethanol-SAE at level of 1,8 g/kg (P3), diets plus methanol-SAE at level of 0.9 g/kg (P4), and diets plus methanol-SAE at level of 1.8 g/kg (P5). Experimental results show that 9 g hot-water-SAE or 0.9 g SAE-methanol supplementation significantly reduced nitrogen content and production of faces. However, SAE inclusion had no effect on phosphor content of faeces (P<0,05). SAE inclusion significantly affected the number of Salmonella sp., Staphylococcus sp., Escherichia coli, Lactobacillus sp., Bacillus subtilis (P<0,05) and Streptococcus sp. (P<0,01). In conclusion, inclusion of ethanol-SAE at level of 1.8 g/kg diets was effective to reduce Salmonella sp and Escherichia coli in feces. Inclusion of 9 g hot-water-SAE or 0.9 g methanol-SAE was effective to reduce nitrogen production and content in feces (Jurnal Pengembangan Peternakan Tropis).

teguh rafian (E1C011046)
ternyata dengan air panas-SAE 9 g atau methanol-SAE 0,9 g mampu mengurangi produksi nitrogen, ini sangat berguna dalam mengurangi polusi nitrogen dalam feses dan kandang.
