        We aimed to evaluate antithrombotic efficacy of Protaetia brevitarsis extract during 21 days. Rats (SPF rat, weight 240~260 g) were divided into 16 groups (5 rats per group), they were: control group and Protaetia brevitarsis extract groups with dose of 0.1, 0.5, 1, 2.5, 5, 10, 25, 50, 75, 100, 200, 250, 500, 750, 1,000 mg/kg kg of body weight. Thromboplastin time (PT) and activated partial thromboplastin time (aPPT) as antithrombotic efficacy were tested in this animal experiment (at 7, 14 and 21 days). Overall, the admistration dose of Protaetia brevitarsis extract over 50 mg/kg at 7, 14 and 21 days for PT and over 25 mg/kg at 7, 14 and 21 days for aPPT tented to be longer than that of other groups. In addition, the optimal admistration doses of Protaetia brevitarsis extract to improves antithrombotic efficacy were 75, 100, 200 and 250 mg/kg at 7, 14 and 21 days for PT (p<0.05) and 50 and 100 mg/kg at 7 days, 75 mg/kg at 14 days, or 50, 100, 200 and 250 mg/kg at 21 days for aPPT (p<0.05). It can be concluded that Protaetia brevitarsis extract at optimal levels have antithrombotic efficacy.

        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.

        This study was conducted to evaluate the growth performance of broilers fed different levels of Hermetia illucens powder. A total of 400 broiler chicks (1-day old Arbor Acres) were fed commercial diets containing H. illucens powder at 0%, 0.1%, 0.5%, and 1% with four replicates (25 chicks per replicate), for 35 days. Weight gain in broilers fed diets containing different levels of H. illucens powder increased significantly at 28 and 35 days, compared with that of the control (p<0.05). However, feed intake and mortality showed no differences among the treatments as a function of time. At 21, 28, and 35 days, broilers fed different levels of H. illucens powder had lower feed conversion rates (p<0.05) than their counterparts fed the control diet. In conclusion, 0.5% H. illucens powder is the optimal level for improved weight gain and feed conversion.
