Effect of dietary supplementation of chitosan from black soldier fly on immune traits and blood chemical parameters of broilers.

The purpose of this experiment was to investigate the effect of dietary supplementation of chitosan from black soldier fly on immune traits and blood chemical parameters of broilers. A total of 400-day old male broiler chicks were randomly allotted into the basic diet, 0.01% chitosan, 0.05% chitosan, 0.05% commercial chitosan and 0.05% larvae. The results indicated that IL-1β titer in 0.05% commercial chitosan and 0.05% larvae group was significantly higher than that in basic diet group (P < 0.05). The GOT in 0.05% commercial chitosan group was significantly lower than that in the basic diet group (P < 0.05). The A/G ratio in 0.05% commercial chitosan group and 0.05% larvae group was significantly lower than that in the basic diet group (P < 0.05). The LDL in 0.05% larvae group was significantly higher than that in the basic diet group (P < 0.05). In conclusion, dietary supplementation of 0.05% commercial chitosan and 0.05% larvae can stimulate serum IL-1β concentration. In addition, 0.05% commercial chitosan can regulate liver function.
