| Abstract: | The aim of the present study was to evaluate the effects of feeding fermentatively recovered fish oil (FFO) from fish processing waste (FPW), on the performance and carcass composition of broilers. A total of 60 one-d-old VenCobb® broiler chicks randomly assigned to 5 treatment groups were studied. The birds were randomly assigned to treatment groups and fed with a normal commercial diet (control, T1), a diet with 2% groundnut oil (positive control, T2), a diet with 1% FFO (T3), a diet with 1.5% FFO (T4) and a diet with 2% FFO (T5). Performance and growth parameters (feed intake and body weight) and fatty acid composition of serum, liver and meat were determined. The performance characteristics of broiler meat did not differ among treatments. Feeding FFO reduced total cholesterol concentration in serum, meat and liver of the FFO-fed groups (T3 to T5) as compared to both the controls (T1 and T2), but there was no significant difference in triglyceride concentration between treatments. Increased concentrations of EPA and DHA in serum, liver and meat of FFO-fed groups, as compared to both controls, were observed as the FFO concentration increased. The study clearly demonstrates the value of oil recovered from FPW in addition to addressing the environmental issues related to disposal of such biological waste.
