Abstract
Herein the effect of supplementing ground sago palm trunk (GSPT) with varying concentrations of plant-based ingredients (PIs) including rice bran (RB) soybean meal (SM) and perilla seed (PS) on the nutritional profile of sago palm weevil larvae (SPWL) was investigated. Increased PS intake induced an increase in ?-linolenic acid level and a reduction in the n-6/n-3 ratio in SPWL (p < 0.05). The presence of fatty acids in SPWL was determined predominantly by the fatty acid profile in the feed. The activities of ?5 + ?6 desaturases and thioesterase were not different among SPWL fed different diets (p < 0.05); however PI intake resulted in low suppression of fads2 gene expression. RB SM and PS at the appropriate concentrations of 17.5% 8.8% and 7.0% in GSPT (F3 diet) respectively boosted both protein quantity and quality of SPWL as indicated by higher levels of essential amino acids particularly lysine than the FAO protein reference. Therefore incorporating PIs into a regular diet is a viable method for enhancing the nutritional value and sustainability of farm-raised SPWL as a potential alternative source of high-quality lipid and protein. ? 2023 by the authors.
