This study was conducted to examine the performance of poultry production and ammonia emissions from poultry litter when the mealworm (Tenebrio molitor L.) powder was fed to broilers and ducks. In Experiment 1, a total of 180 1-day-old broilers (Arbor acres) were allocated to two treatments with three replicates in a completely randomized design. In Experiment 2, ducks were used in the same method as in Experiment 1. The dietary treatments were as follows: basal diets as control and basal diets with 1.5% Tenebrio molitor L. powder as T1. In Experiment 1, broiler production was not affected by the addition of mealworm powder (p>0.05). Ammonia from broiler litter was observed significantly different in the two treatments at 4 and 5 weeks (p<0.05); however, in other weeks ammonia measured did not show significance different (p>0.05). In Experiment 2, feeding of mealworm powder had no statistical significance on duck productivity (p>0.05). Ammonia emissions from duck litter were not statistically significant in the two treatments at 2 to 5 weeks (p>0.05); however, there was a difference at 6 weeks (p<0.05). Therefore, the addition of mealworm powder to broiler and duck diets did not only improved weight gain and feed efficiency, but also effectively reduced ammonia in poultry litter.

This study was conducted to investigate the effects of adding Tenebrio molitor L Powder to broiler feed on fatty acid profiles in broiler breast meat. In total, 180 broiler chicks (1-day old Arbor Acres) were included. The birds were randomly divided into control and treatment groups, with 3 replicate subgroups each(30 birds per subgroup), and fed a diet for 35 days without (control) or with 1% Tenebrio molitor L powder (treatment). Among individual fatty acids, addition of Tenebrio molitor L. powder resulted in slightly higher C18:1n-9, C20:3n-3 and C20:3n-6 contents, and lower C18:2n-6 content compared withcontrols (p<0.05). No remarkable differences in total SFA and total USFA contents were found between groups. In conclusion, inclusion of Tenebrio molitor L. in broiler diets did not improve overall fatty acid profiles.
