Abstrakt: The goal of this experiment was to examine the effect of dietary inclusion of full-fatted mealworm larvae (FFML) or hydrolysate mealworm larvae (HML) (Tenebrio molitor) as a substitute for spray-dried plasma protein (SDPP) as a protein source on the performance and immune status of nursery pigs. A total of 150 crossbred piglets (6.48 ± 0.01 kg) were randomly allocated to 1 of 3 dietary groups in two feeding phases: phase 1 (Days 0-14) and phase 2 (Days 15-35). Each treatment had 10 replicates with 5 pigs per replicate. The nutritious diets were: Phase 1: SDPP-CON (control-basal diet) + 6% SDPP diet; FFML-CON + 3% SDPP and 3% FFML diet; HML-CON + 3% SDPP and 3% HML diet. Phase 2: SDPP-CON (basal diet) + 3% SDPP diet; FFML-CON + 3% FFML diet; HML-CON + 3% HML diet. The inclusion of FFML or HML diet did not show significant difference but had a comparable effect as that of standard control diet containing SDPP on the growth performance, nutrient digestibility and faecal score throughout the trial. In comparison to pigs fed SDPP diet, pigs fed FFML and HML diets had similar and/or higher (p < 0.05) serum immunoglobulin (IgA and IgG) concentration at the end of phase 1 and 2. The result of the present study indictes that SDPP would be partially or fully replaced with FFML or HML to suit weaning pigs diet.
