Growth Performance, Gut Health, Welfare and Qualitative Behavior Characteristics of Broilers Fed Diets Supplemented with Dried Common (Olea europaea) Olive Pulp

The present study investigated the dietary impact of dried olive pulp (OP) on growth performance, gut health and some welfare behavior characteristics broilers. It was conducted in a commercial poultry farm using 108 13 day-old Ross male Chickens were equally randomly assigned to 3 treatments, CON, OP3 OP6, based incorporation rate OP ration (0%, 3%, 6%, respectively). A beneficial foot pad dermatitis (FPD) feather cleanliness OP-fed broilers recorded. No adverse effects qualitative evaluated overall performance chickens observed. significant differences fecal microbiota population observed among groups. Changes β-diversity an age-dependent way only feces across all age groups mainly dominated by phylum Firmicutes (62.3 95.1%), represented genus Lactobacillus (32.9 78.2%), Proteobacteria (2.0 35.6%), Actinobacteria (1.5 11.4%). Supplementing broilers’ diets with 3% 6% beneficially affected chickens’ without compromising their health.
