Effects of Partially Defatted Black Soldier Fly Larvae (Hermetia illucens) Based Diets on Growth Performance, Nutrient Digestibility, and Serum Biochemistry Profile of Weaned Pigs
Abstract
This study investigated the effects of partially defatted Black Soldier Fly larvae (DBSFL) meal as a replacement for soybean meal in weaned pig diets. Twenty-seven crossbred weaned pigs (Large White x Landrace, initial weight 8.26 ± 0.13 kg) were randomly assigned to three dietary treatments: 0%, 5%, and 10% DBSFL meal, replacing soybean meal at 0, 25, and 50% inclusion levels, respectively. The 49day experiment assessed growth performance, nutrient digestibility, and serum biochemistry. No significant differences (P>0.05) were observed in growth performance parameters or nutrient digestibility. Serum biochemistry showed no significant differences in ALT, ALP, albumin, total protein, and LDL. However, AST levels were higher in pigs fed 5% DBSFL (56.07 U/L) compared to those fed 0% (36.82 U/L) and 10% (53.61 U/L) DBSFL. Total cholesterol and HDL levels were significantly higher (P<0.05) in the 5% DBSFL group (164.55 mg/dL and 74.91 mg/dL, respectively) compared to the 0% (138.56 mg/dL and 38.07 mg/dL) and 10% (148.94 mg/dL and 62.28 mg/dL) groups. Triglyceride concentrations increased with DBSFL inclusion (0%: 51.27 mg/dL; 5%: 61.43 mg/dL; 10%: 72.21 mg/dL). In conclusion, DBSFL meal can partially replace soybean meal in weaned pig diets without negatively affecting growth performance, nutrient digestibility, serum profile, and overall health of the weaned pigs.
