A diet supplemented with hazelnut skin changes the microbial community composition and the biohydrogenation pattern of linoleic acid in the rumen of growing lambs

The reuse of by-products from the agro-industry in animal feeding is desirable to increase sustainability productions. Hazelnut skin a by-product food industry and due high content crude fat phenolic compounds can be potentially used ruminants’ diet. In this study, we characterised compared microbial communities rumen digesta (RD) lambs fed diet supplied with hazelnut vs. control Microbial DNA was extracted high-throughput sequencing 16S rRNA gene amplicons performed. Six genera ([Eubacterium] nodatum group, Acidaminococcus, Dialister, Erysipelotrichaceae UCG-002, Megasphaera, Olsenella) showed positive correlation concentration C18:1 t10, their relative abundance higher RD diet, skin. results suggest that microorganisms correlated t10 production animals concentrate-based reduced by administration skin.HighlightsA affected community lambsThe genus Dialister decreased skinAdministration strategy reduce t10/t11 ratio
