摘要： Silkworm (Bombyx mori) pupae (SWP) is a promising feed source with high nutritional value. In present study, the effects of different proportion of solid-state fermented silkworm pupa as a fishmeal substitute were evaluated on the growth performance, immune organ indices, serum biochemical parameters, and meat quality of Lingnan yellow broiler chickens. Lingnan yellow broilers were randomly categorized into 4 groups. The control group was fed with basal diet containing 3% fishmeal, and the treatment group 1, 2, and 3 were fed basal diet with 30%, 60%, and 100% fishmeal substituted with fermented silkworm pupae (FSP), respectively. Broilers were fed the treatment diets in phase 1 (1-21 d) and phase 2 (22-42 d) during the experimental period. Results showed a non-significant difference (P > 0.05) between control and treatment groups on the average daily weight gain (ADG), average daily feed intake (ADFI), and feed conversion ratio (feed/gain, F/G) at 21d. At 42 d, the F/G of three treatment groups were all less than the control group. Moreover, the broiler meat quality increased with treatment group compared with the control at 42 d. It also showed that FSP addition could improve the thymic index of broilers at both 21 and 42 d. Among the above treatments, Treatment 3 reached a significant level (P < 0.05) as compared to the control in F/G, thymic index and meat quality. All treatment groups had a lower drip loss in meat quality compared to control, and Treatment 1 reached a significant level (P < 0.05). In conclusion, the FSP can be employed as a potential economical substitute for the fishmeal to Lingnan yellow broiler chickens.
