Accessing the impact of harvest weights of <i>Tenebrio molitor</i> on amino acid digestibility and metabolizable energy in cecectomized laying hens
The present study did not indicate that partially defatted TM larvae of different harvest weights influenced AA digestibility and ME<sub>N</sub>, whereas AA digestibility and ME<sub>N</sub> of pupae was higher. Feeding partially defatted TM pupae instead of larvae could reduce nitrogenous emissions during egg production, provided that emissions from pupae production remain low. Therefore, optimizing the defatting process for TM pupae may help mitigate challenges associated with the higher fat content, potentially enabling the realization of the benefits from its higher AA digestibility in feed applications. © 2025 The Author(s).
