Abstract

The effects of enzyme supplementation of shrimp waste meal (SWM) based diets on the performance and nutrient utilization of starter and finisher broilers were studied. One hundred and twenty day old broilers (Anak strain) were randomly divided into four groups of 30 birds each. Each group was further divided into three replicates of 10 birds each. The birds were assigned the four dietary treatment in 2 X 2 factorial design. Diets 1 and 3 had fish meal as the sole animal protein source, diets 2 and 4 had shrimp waste as the animal protein source. Diets 1 and 2 were without enzymes while diets 3 and 4 were supplemented with enzyme. Records of performance, nutrient utilization, blood parameters and carcass characteristics were taken. The values of average final weight, daily weight gain, feed conversion ratio and protein efficiency ratio at starter and finisher phases were not significantly (P>0.05) influenced by the dietary treatment. The daily feed intake of the starter broilers fed diet 3 (fish meal based diets with enzyme) was significantly (P<0.05) higher than those of other treatment. Birds fed fish meal diet without enzyme had the highest serum uric acid and serum cholesterol at the starter phase. Finisher broiler fed fish meal based diet without enzyme had a significantly (P<0.05) higher serum creatinine value. Carcass characteristics measured were not significantly influenced by the dietary treatments. It was concluded that SWM can be employed as an animal protein source in broiler diets. The exogenous enzyme (Roxazyme G) used did not effect any appreciable improvement on the utilization of SWM based diets.
