Abstract

This study investigates the effectiveness of Clanis bilineata (Soybean hawkmoth) larvae (CBL) as a novel alternative for soybean meal in mature laying ducks (64 weeks old). In a randomized controlled trial, 120 ducks were allocated to control (soybean-based diet) and CBL groups (15.79% CBL replacing soybean meal), each comprising six replicates of 10 birds. Over 63 days, CBL supplementation significantly enhanced serum antioxidant defences, with superoxide dismutase (SOD) and glutathione peroxidase (GPx) activities increasing by 15.7% ( P = 0.021) and 44.0% ( P = 0.003), respectively, compared to the control. Daily egg production rose by 12.1% ( P = 0.012), egg mass by 21.7% ( P = 0.008), and yolk colour intensity by 21.9% ( P = 0.015). CBL also elevated immunoglobulins (IgG: +48.3%, P = 0.004; IgA: +27.8%, P = 0.038; IgM: +43.5%, P = 0.006) and high-density lipoprotein levels (+23.7%, P = 0.017), while reducing serum triglycerides (−25.0%, P = 0.009) and total cholesterol (−11.4%, P = 0.026). Feed efficiency improved by 11.8% ( P = 0.019) without compromising feed intake, eggshell integrity, or albumen quality. Notably, CBL supplementation caused no adverse effects on feed consumption, eggshell integrity, or albumen quality. Simultaneously, feed efficiency increased by 11.8% ( P = 0.019). These findings demonstrate that CBL decreases oxidative stress and age-related metabolic dysregulation, making it a promising dietary intervention for increasing aging ducks production. The findings show that insect-derived proteins have the potential to alleviate global feed supply challenges while also increasing the ecological and economical sustainability of animal husbandry.
