摘要
The present experiment was conducted to test the effect of a 4% defatted silkworm ( Bombyx mori ) pupae meal (SWM) incorporation into chickens ' diets at different growth phases on meat quality characteristics and sensory traits. Ninety ROSS 308 day-old male broiler chickens were randomly assigned to 3 dietary groups, with 5 replicated pens/diet: the first group received a control (C) diet throughout the growing period of 42 d, the second group received a diet with 4% SWM (SWM1) during the starter phase (1 -10 d) and the C diet up to slaughter, whereas the third group was fed the C diet during the starter phase and 4% SWM during the grower and finisher phases (SWM2). Diets were isonitrogenous and isoenergy, and birds had free access to feed and water throughout the experimental trial. At 42 d of age, 15 chickens/treatment were slaughtered at a commercial abattoir. Fatty acid (FA) and amino acid (AA) pro files and contents of meat, as well as its oxidative status, were determined in both breast and leg meat cuts. Also, a descriptive sensory analysis was performed on breast meat by trained panelists. Results highlighted that the SWM2 treatment increased the n -3 proportion and content in both breast and leg meat, thereby improving the omega-6/omega-3 ( n -6/ n -3) ratio in both cuts ( P < 0.001). However, the dietary treatment had no signi ficant effect on the oxidative status of either breast or leg meat ( P > 0.05). The SWM had a limited impact on overall sensory traits of breast meat, but it contributed to improve meat tenderness in SWM-fed chickens ( P < 0.01). Furthermore, SWM1 meat exhibited higher juiciness ( P < 0.05) and off flavor intensity ( P < 0.05) compared to the control meat. Overall, the present experiment indicated that defatted SWM holds promise as an alternative ingredient in chicken rations, ensuring satisfactory meat quality. Furthermore, administering SWM during the grower- finisher phase demonstrated bene ficial effects on meat healthiness, ultimately enhancing n -3 fatty acids content and reducing the n -6/ n -3 ratio.
