Abstract
Beneficial effect of feeding olive pulp and <i>Aspergillus awamori</i> on productive performance, egg quality, serum/yolk cholesterol and oxidative status in laying Japanese quails
Highlights
Poultry industry faces realistic challenge and ever-increasing problem of incessant rising in prices and limited amounts of high-quality feed materials
The Egg number (EN) was increased in all groups receiving olive pulp (OP) regardless A. awamori addition in periods 12–16, 16–20 week of age and the overall period, there was no difference between groups A and C
The highest values of egg weight (EW) and EN were recorded in OP5A and OP10 groups followed by OP5, mainly in overall period
Summary
Poultry industry faces realistic challenge and ever-increasing problem of incessant rising in prices and limited amounts of high-quality feed materials. The feed costs can be reduced by using low-cost and locally available feedstuffs. It is required to constantly evaluate new feed sources, including agriculture by-products and food-industry wastes. Olive pulp (Olea europaea L., OP) represents one of the residues used as partially alternative to feed ingredients. OP is the remaining raw material from the olive oil extraction (mechanical or solvent method) after the removal of the seed fractions. Depending on oil extraction method, crude fat content can vary in the pulps. The OP may be partly considered as
