Abstract:
The effects of substitution of poultry offal meal (POM) for soybean meal (SBM) and the effect of sup plementation of POM by a mixture of solid state fermentation enzymes (SSF) and Lipase on egg quality
traits of Japanese quails were studied in two experiments. Unsexed Japanese quails (13 days old;
N=200) were randomly assigned to twenty groups of ten birds for each experiment. In experiment 1,
POM was incorporated at 0, 2.5, 5, 7.5 and 10% in the diets to assess the maximum inclusion level of
POM. In Experiment 2, the egg quality of Japanese quails fed diets containing 0, 5 and 10% POM was
investigated. Enzyme effect was tested at 5 and 10% POM. The major egg quality traits and sensory
qualities were assessed. Feeding POM at 10% rate significantly (P<0.05) lowered shell ratio, egg
weights and unit surface shell weight (USSW) by 4.6, 4.2 and 5.6% respectively compared to the control
diet. However, POM could be incorporated up to 10% with no detrimental effects on internal quality
traits and consumer’s preference. Experiment 1 concluded that, 2.5% POM is the best in terms of ex ternal quality traits. Enzyme supplementation did not affect egg quality traits except for the improve ment of albumen index by 5.9% at 10% POM.
