Total substitution of soybean meal with Hermetia illucens meal in laying hens: effect on lipid composition of yolk

The present study aims to fit this gap by testing a 100% replacing diet with Hermetia illucens defatted meal. One-hundred and eight Lohman Brown Classic laying hens were farmed for 21 weeks and divided into 2 groups fed two isoproteic and isoenergetic diets, differing in the main protein source: corn-soybean meal based diet (SB group) or Hermetia illucens larve defatted meal (HI group). Despite, the high presence of saturated fatty acid in Hermetia illucens meal, fatty acid composition of yolk did not show to be significantly damaged especially concerning polyunsaturated n-3 and n-6 fractions.
