At the same time, the growing demand by markets worldwide, especially in Africa and Southeast Asia, can justify the growing interest in the use of by-products for the poultry industry. Olive pulp is one of the most interesting by-products of olive tree farming (typical of the Mediterranean area), being a good source of many biologically active compounds with antioxidant, antifungal, and antibacterial properties. The presence of processed olive pulp in the diet showed to be effective in increasing the weight of specific carcass and offal traits. This work aims at studying olive pulp as a feed supplement in poultry nutrition, by focusing on the effects on broiler carcass and offal. Olive pulp (OP) is one of the by-products of olive tree farming, being the residue of olive cake after it is dried. To evaluate the effects of OP in a diet supplemented with different levels of a commercial enzyme (ENZ) blend on broiler carcass and offal traits, three hundred male broiler chicks (Ross 308 lineage; one-day-old) were divided into ten treatment groups according to a completely randomized design. The treatments diets contained: unprocessed OP (50 g\/kg, 100 g\/kg, 50 g\/kg with ENZ, 100 g\/kg with ENZ), processed OP (50 g\/kg, 100 g\/kg, 50 g\/kg with ENZ, 100 g\/kg with ENZ), and control groups (without OP, and without OP with ENZ). The OP processing increased breast percentages in broilers. Supplementation with ENZ did not change any of the studied carcass or offal trait values. The presence of OP (50 g\/kg) in broiler diets increased the eviscerated carcass, leg, and neck percentage values. The presence of processed OP (50 g\/kg) in the diet showed to be effective in increasing the weight of specific carcass and offal traits.<\/jats:p>","DOI":"10.3390\/agriculture10080359","type":"journal-article","created":{"date-parts":[[2020,8,14]],"date-time":"2020-08-14T13:00:18Z","timestamp":1597410018000},"page":"359","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Olive Pulp and Exogenous Enzymes Feed Supplementation Effect on the Carcass and Offal in Broilers: A Preliminary Study"],"prefix":"10.3390","volume":"10","author":[{"given":"Peyman","family":"Sayehban","sequence":"first","affiliation":[{"name":"Department of Animal Science, Rasht Branch, Islamic Azad University, Rasht 41335-3516, Iran"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1903-2753","authenticated-orcid":false,"given":"Alireza","family":"Seidavi","sequence":"additional","affiliation":[{"name":"Department of Animal Science, Rasht Branch, Islamic Azad University, Rasht 41335-3516, Iran"}]},{"given":"Mohammad","family":"Dadashbeiki","sequence":"additional","affiliation":[{"name":"Department of Veterinary Science, Rasht Branch, Islamic Azad University, Rasht 41335-3516, Iran"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7775-2057","authenticated-orcid":false,"given":"Ahmad","family":"Ghorbani","sequence":"additional","affiliation":[{"name":"Guilan Agricultural and Natural Resources Education and Research Center, Rasht 14445-41996, Iran"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9106-643X","authenticated-orcid":false,"given":"Wagner Azis Garcia","family":"de Ara\u00fajo","sequence":"additional","affiliation":[{"name":"Instituto de Educa\u00e7\u00e3o, Ci\u00eancia e Tecnologia Norte de Minas Gerais, Janu\u00e1ria 39480-000, MG, Brazil"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7747-9107","authenticated-orcid":false,"given":"Alessandra","family":"Durazzo","sequence":"additional","affiliation":[{"name":"CREA-Research Centre for Food and Nutrition, Via Ardeatina 546, 00178 Rome, Italy"}]},{"given":"Massimo","family":"Lucarini","sequence":"additional","affiliation":[{"name":"CREA-Research Centre for Food and Nutrition, Via Ardeatina 546, 00178 Rome, Italy"}]},{"given":"Paolo","family":"Gabrielli","sequence":"additional","affiliation":[{"name":"CREA-Research Centre for Food and Nutrition, Via Ardeatina 546, 00178 Rome, Italy"}]},{"given":"Besma","family":"Omri","sequence":"additional","affiliation":[{"name":"Laboratory of Improvement and Integrated Development of Animal Productivity and Food Resources, Department of Animal Production, Higher School of Agriculture of Mateur, University of Carthage, 1054 Carthage, Tunisia"},{"name":"National Agronomy Institute-Tunis, University of Carthage, 1054 Carthage, Tunisia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2753-2010","authenticated-orcid":false,"given":"Luiz Fernando","family":"Teixeira Albino","sequence":"additional","affiliation":[{"name":"Department of Animal Science, Universidade Federal de Vi\u00e7osa, Vi\u00e7osa 36570-000, MG, Brazil"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9737-6017","authenticated-orcid":false,"given":"Eliana B.","family":"Souto","sequence":"additional","affiliation":[{"name":"Department of Pharmaceutical Technology, Faculty of Pharmacy, University of Coimbra (FFUC), P\u00f3lo das Ci\u00eancias da Sa\u00fade, 3000-548 Coimbra, Portugal"},{"name":"CEB\u2014Centre of Biological Engineering, University of Minho, Campus de Gualtar, 4710-057 Braga, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5505-3327","authenticated-orcid":false,"given":"Antonello","family":"Santini","sequence":"additional","affiliation":[{"name":"Department of Pharmacy, University of Napoli Federico II, Via D.
