Accessing the impact of harvest weights of Tenebrio molitor on amino acid digestibility and metabolizable energy in cecectomized laying hens.

ABSTRACT:

Background

The effects of harvest weights on composition, amino acid (AA) digestibility and metabolizable energy (ME_N) of Tenebrio molitor (TM) were investigated using cecectomized laying hens. The partially defatted and dried TM variants comprised median individual frass-free harvest weights of 60, 80, 100, and 120 mg of larvae, and a pupae weight of 125 mg. Diets containing the five TM variants and a basal diet were fed to six cecectomized laying hens over six experimental periods in a 6 × 6 Latin square design.

Results

The AA concentrations relative to crude protein were similar among the TM larvae variants. Crude protein and crude fat contents did not differ between the larvae variants. Pupae had a lower crude protein and a higher crude fat concentration compa
