It was also verify whether generated changes would make the giblets and wastes more valuable as dietary components or by\u2010products for food industry. From 22 to 42\u00a0day of life, five diets were administered to chickens. Control grower diet (CON) contained 5% of soy oil, whereas in the experimental grower diets part of soy oil (1.5% or 2%) was replaced with specific amount of grape or pomegranate seed oil (GRAP 1.5; GRAP 2.0; POM 1.5; POM 2.0 respectively). Fatty acids and cholesterol content were determined with gas chromatography with flame\u2010ionization detection. Pomegranate seed oil improved fatty acids profile more favourably than grape seed oil, which makes it a valuable additive in chickens\u2019 feeding. Abdominal fat of pomegranate seed oil supplemented chickens appeared to be the richest sources of rumenic acid and n3 polyunsaturated fatty acids, which allows to suggest its use in manufacturing of meat products to obtain foodstuffs rich in those essential nutrients. In principal component analysis (PCA), two principal components: PC1 and PC2, which were enough to explain 29.91% of variance of initial variables, allowed to a good separation of chickens fed with both doses of pomegranate seed oil from animals from control and grape seed oil fed groups. Because poultry addresses all nutritional, institutional and consumer requirements, enrichment of giblets in rumenic acid by pomegranate seed oil incorporation into chickens\u2019 diet may provide a valuable dietary source of bioactive fatty acids for consumers, especially of low\u2010income countries.<\/jats:p>","DOI":"10.1111\/jpn.13464","type":"journal-article","created":{"date-parts":[[2020,10,27]],"date-time":"2020-10-27T06:37:43Z","timestamp":1603780663000},"page":"520-534","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Giblets and abdominal fat of pomegranate seed oil fed chickens as a source of bioactive fatty acids"],"prefix":"10.1111","volume":"105","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7879-300X","authenticated-orcid":false,"given":"Agnieszka","family":"Bia\u0142ek","sequence":"first","affiliation":[{"name":"Department of Bromatology Medical University of Warsaw Warszawa Poland"},{"name":"Department of Biotechnology and Nutrigenomics Institute of Genetics and Animal Biotechnology of the Polish Academy of Sciences Magdalenka Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2003-8642","authenticated-orcid":false,"given":"Ma\u0142gorzata","family":"Bia\u0142ek","sequence":"additional","affiliation":[{"name":"The Kielanowski Institute of Animal Physiology and Nutrition Polish Academy of Sciences Jab\u0142onna Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ma\u0142gorzata","family":"Czerwonka","sequence":"additional","affiliation":[{"name":"Department of Bromatology Medical University of Warsaw Warszawa Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tomasz","family":"Lepionka","sequence":"additional","affiliation":[{"name":"Laboratory of Hygiene Food and Nutrition Military Institute of Hygiene and Epidemiology Warsaw Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Natalia","family":"Tytz","sequence":"additional","affiliation":[{"name":"Department of Bromatology Medical University of Warsaw Warszawa Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Karolina","family":"Kucharczyk","sequence":"additional","affiliation":[{"name":"Department of Bromatology Medical University of Warsaw Warszawa Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"El\u017cbieta","family":"Tober","sequence":"additional","affiliation":[{"name":"Department of Biotechnology and Nutrigenomics Institute of Genetics and Animal Biotechnology of the Polish Academy of Sciences Magdalenka Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Karol","family":"Kaszperuk","sequence":"additional","affiliation":[{"name":"Institute of Zootechnics and Fisheries Faculty of Agrobioengineering and Animal Sciences Siedlce University of Natural Sciences and Humanities in Siedlce Siedlce Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Teresa","family":"Banaszkiewicz","sequence":"additional","affiliation":[{"name":"Institute of Zootechnics and Fisheries Faculty of Agrobioengineering and Animal Sciences Siedlce University of Natural Sciences and Humanities in Siedlce Siedlce Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2020,10,26]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11356-017-0514-0"},{"key":"e_1_2_7_3_1","article-title":"Enrichment of quail (coturnix cot. japonica) eggs by omega\u20103 fatty acids and its nutritional effect on young healthy women.
