Production Performance, Egg Quality Characteristics, Fatty Acid Profile and Health Lipid Indices of Produced Eggs, Blood Biochemical Parameters and Welfare Indicators of Laying Hens Fed Dried Olive Pulp

This study aimed to evaluate the long-term dietary effects of dried olive pulp (OP) on production performance, fatty acid profile and health lipid indices quality characteristics produced eggs, welfare indicators laying hens. It was carried out in a commercial poultry farm using 300 Isa Brown layers at 23 weeks age. The hens were randomly equally divided six groups CON, OP2, OP3, OP4, OP5 OP6, according inclusion rate OP ration (0%, 2%, 3%, 4%, 5% 6%, respectively). feeding increased percentage polyunsaturated acids (PUFA) decreased that saturated (SFA) improved PUFA SFA ratio indices, as indicated by decrease AI TI increase h/H dose-dependent way. OP-fed presented lower broken eggshells compared controls. No adverse birds’ egg traits, parameters observed but positive impact Keel Bone Damage (KBD) incidence belly plumage damage recorded. rates 6% seems be beneficial improving nutrition quality.
