摘要

Background:The study aimec to determine the apparent total tract digestibility coefficients (ATTDC) of nutrients,the apparent metabolizable energy (AME and AMEn) and the amino acid (AA) apparent ileal digestibility coefficients (AIDC) of a partially defatted (BSFp) and a highly defatted (BSFh) black soldier fly larvae meal.The experimental diets were:a basal diet and two diets prepared by substituting 250 g/kg (w/w) of the basal diet with BSFp or BSFh,respectively.Results:Significant differences were found between BSFp and BSFh meals for ATTDC of the nutrients:BSFp resulted more digestible than BSFh,except for ATTDC of CP which did not differed between meals,while a statistical trend was observed for ATTDC of DM ancl EE.The AME and AMEn values were significantly (P ＜ 0.05) different between the two BSF meals,with higher levels for BSFp (16.25 and 14.87 MJ/kg DM,respectively).The AIDC of the AA in BSFp ranged from 0.44 to 0.92,while in BSFh they ranged from 0.45 to 0.99.No significant differences were observed for the AA digestibility (0.77 and 0.80 for BSFp and BSFh,respectively),except for glutamic acid,proline and serine that were more digestible in the BSFh meal (P ＜ 0.05).Conclusions:Defatted BSF meals can be considered as an excellent source of AME and digestible AA for broilers with a better efficient nutrient digestion.These considerations suggested the effective utilization of defatted BSF larvae meal in poultry feed formulation.
