This study was designed to evaluate the influence of dietary supplementation of Tenebrio molitor larvae (TM) as an alternative source of protein to fish meal on growth response, retention of nutrient, hematological factors, immune system, and intestinal integrity in weaned pigs. A total of 180 weanling pigs (initial bodyweight of 6.27 ± 0.15 kg; 21 d) were distributed based on the bodyweight between 3 treatments with 6 replicates in each treatment including 10 piglets per replicate. The diets corresponding to treatments consisted of a fish meal diet (CON), a fish meal–dried mealworm diet (TM1, 50% replacement of fish meal with TM meal), and a dried mealworm diet (TM2, 100% replacement of fish meal with TM meal). This study was performed in two phases as phase 1 (d 0 to 14) and phase 2 (d 15 to 28). The pigs in the TM2 treatment showed a greater gain to feed ratio compared with the TM1 pigs in phase 1. Throughout the experimental period, the average daily gain (ADG) of the TM1 pigs was significantly greater than that of the TM2 treatment. The IgG concentration was increased in the TM1 and TM2 treatments compared with the CON pigs in phase 1. In conclusion, the supplementation of TM meal (50% replacement of fish meal) did not show any adverse effects in the performance of weanling pigs, however, 100% replacement of fish meal with TM meal is not recommended.
Abstract
This study was designed to evaluate the influence of dietary supplementation of Tenebrio molitor larvae (TM) as an alternative source of protein to fish meal on growth response, retention of nutrient, hematological factors, immune system, and intestinal integrity in weaned pigs. A total of 180 weanling pigs (initial bodyweight of 6.27 ± 0.15 kg; 21 d) were distributed based on the bodyweight between 3 treatments with 6 replicates in each treatment including 10 piglets per replicate. The diets corresponding to treatments consisted of a fish meal diet (CON), a fish meal–dried mealworm diet (TM1, 50% replacement of fish meal with TM meal), and a dried mealworm diet (TM2, 100% replacement of fish meal with TM meal). This study was performed in two phases as phase 1 (d 0 to 14) and phase 2 (d 15 to 28). The pigs in the TM2 treatment showed a greater gain to feed ratio compared with the TM1 pigs in phase 1. Throughout the experimental period, the average daily gain (ADG) of the TM1 pigs was significantly greater than that of the TM2 treatment. The IgG concentration was increased in the TM1 and TM2 treatments compared with the CON pigs in phase 1. In conclusion, the supplementation of TM meal (50% replacement of fish meal) did not show any adverse effects in the performance of weanling pigs, however, 100% replacement of fish meal with TM meal is not recommended.
