Synopsis
The metabolisable energy value of pupae of Musca domestica L. and digested poultry manure was determined to be 10.6 and 2.4 MJ/g (2528 and 580 kcal/g), respectively. Chemical analyses showed that pupae contained 61.4% protein and 9.3% fat: their amino acid composition was comparable with that of meat‐and‐bone meal or fish meal and was better than soybean oil meal.
A feeding trial was conducted to evaluate house fly pupae and catabolised poultry residue as alternative protein sources to soybean meal for growing chickens.
No significant difference (P>0.05) in weight gain was observed between the control and chicks fed pupae in their diet from 1 d to 4 weeks of age. Food conversion of the chicks fed digested poultry manure was significantly (P<0.05) inferior to that of the controls.
