effect of preserved decanted palm oil mill effluent (pome) on growing poultry
S. W Yeong and A. Azizah
Abstract
Decanted palm oil mill effluent (POME) which was preserved in sodium benzoate (2 g/kg) contained 21%-23% dry matter (DM) and 15.7% crude protein on DM basis. It was included at 10% level in broiler and 20% level in Pekin duck diets (DM basis) to test their acceptability and effect on growth performance. In both trials, the diets were compared with a corn-soy basal diet (control diet) and a diet with the same level (DM basis) of mechanically dehydrated POME. Results of the digestibility test showed that the dry matter digestibility and nitrogen retention in the diet containing 10% decanted POME were significantly higher compared with those fed with the control diet and diet with dehydrated POME. However, the control diet was more superior for these two variables than the diet with dehydrated POME. In a three-week broiler feeding trial (fourth to sixth week), lower feed intake, higher body weight gain and better feed conversion efficiency were observed in birds fed diet with decanted POME, and the lowest weight gain was obtained from birds fed dehydrated POME-based diet. In a five-week Pekin duck trial (fourth to eighth week), the decanted POME group had a slightly higher weight gain and better feed conversion efficiency, although both of these variables were not significantly different. No obvious differences were observed in carcass quality among the ducks in these three diet groups. It was concluded that decanted POME is more digestible and acceptable by chickens and ducks than dehydrated POME.
