Research note: utilizing hazelnut kernel oil meal in layer diets.
The present study was conducted in order to investigate the possibility of utilizing hazelnut kernel oil meal (HKOM) in layer diets as a replacement for soybean oil meal (SBM). Two hundred and sixteen brown egg layers raised in contiguous wire cages were used. The duration of the experiment was 24 wk consisting of six periods of 4 wk. In the trial, six diets containing different levels of HKOM replacing 0, 20, 40, 60, 80, and 100% of SBM protein, respectively, were utilized as the treatments. Differences among the diets in terms of egg yield, feed consumption, feed efficiency ratio, egg weight, egg yolk and albumen ratios, shell thickness, shell weight, and Roche color values of the yolk were not statistically significant (P greater than .01). Results indicated that SBM could be replaced totally by HKOM in layer diets. However, replacement of more than 40% of SBM with HKOM is not recommended.
