Abstract. The present study was conducted to evaluate effect of fermented feces on growth, fat deposition and carcass quality in broiler chickens. Randomized completely factorial design (2 x 2) was used to evaluate the level of feces feeding [10% (L1) or 15% (L2) inclusion to diet] and the level of EM4 to ferment feces [0 (E0), 1.2 (E1) or 6.0 ml/100 g feces (E2)]. Experimental results showed that level of feces feeding had no effect on weight gain and feed conversion ratio (P>0.05), but it significantly increased feed intake (P<0.05). EM4 level had no effect on weight gain and feed conversion ratio, but it significantly increased feed intake (P<0.01). Feeding 10% feces fermented by 1.2 ml EM4 had the lowest mortality. Level of feces feeding had no effect on abdominal fat, carcass weight, carcass percentage, cooking loss, meat bone ratio and drumstick circle. EM4 level also had no effect on those variables. EM4 level significantly increased carcass and meat color (P<0.01), meat taste (P<0.01), and significantly reduced meat smell (P0.05). In conclusion, feeding 1.2 ml EM4 fermented feces at level of 10% resulted in the best performance. Fermented feces resulted in better carcass quality as compared with those of unfermented feces with no effect on abdominal fat deposition (J. Indon. Trop. Anim. Agric., 29 (1): 27-32, 2004.
Key words: EM4, layer faeces, fermentation, performance, carcass quality
