Hazelnut kernel oil meal (HKOM) can fully replace soybean oil meal (SBM) in layer diets without affecting egg production. However, replacing over 40% of SBM with HKOM is not advised.

Area of Science:

  • Animal Science
  • Poultry Nutrition
  • Feed Science

Background:

  • Soybean oil meal (SBM) is a common protein source in layer diets.
  • Exploring alternative protein sources is crucial for feed sustainability and cost-effectiveness.

Purpose of the Study:

  • To evaluate hazelnut kernel oil meal (HKOM) as a viable substitute for SBM in layer diets.
  • To determine the optimal inclusion level of HKOM without compromising layer performance.

Main Methods:

  • Two hundred sixteen brown egg layers were fed diets with 0-100% HKOM replacing SBM protein over 24 weeks.
  • Key performance indicators including egg yield, feed intake, and egg quality parameters were measured.

Main Results:

  • No statistically significant differences were observed in egg yield, feed consumption, feed efficiency, egg weight, yolk/albumen ratios, shell thickness, shell weight, or yolk color.

  • Complete replacement of SBM with HKOM did not negatively impact layer performance.

    • Conclusions:

    • Hazelnut kernel oil meal (HKOM) is a suitable alternative protein source for soybean oil meal (SBM) in layer diets.
    • While total replacement is possible, exceeding 40% HKOM inclusion is not recommended based on the study's findings.
