We investigate the effects of the immune function (HI titer) in broilers fed diets containing Hermetia illucens (H. illucens) peptide extract over a 40-day period. Twenty-four broiler chicks (Arbor Acres, 1 d old) were divided into four groups and fed different diets (control, 0.1%, 0.5%, and 1% H. illucens peptide extract). To evaluate HI titer, all broilers were vaccinated with H9H2 vaccine subcutaneously on the lateral thorax, according to the manufacturer’s recommendations. Similar HI titer was observed with 1% H. illucens peptide extract treatment compared to the control after 40 days (p>0.01). Groups fed 0.5% H. illucens peptide extract demonstrated the most effective immune effects (p<0.01), followed by groups fed 0.1% H. illucens peptide extract. In conclusion, using 0.1% or 0.5% H. illucens peptide extract before or after vaccination improved HI titer immune function in broilers.
