For this purpose, eight multiparous mid-lactating cows were blocked and assigned to one of four treatments and were used in a replicated 4 \u00d7 4 Latin squares design with 21-days periods (14 days of adaptation and 7 of data collection). Two different circular feedstuffs were tested: a bakery\u2019s former foodstuff (FF) and a wheat distiller\u2019s grain with solubles (WDGS). These ingredients were used, alone and in combination, in three experimental diets (FF, WDGS; FF + WDGS) and compared to a standard ration (CTR). Dry matter intake and rumination time were not influenced by these diets. Conversely, dietary treatments partially influenced the milk yield, rumen pH, Volatile Fatty Acids (VFA) production, and fibre digestibility. In particular, the combined inclusion of FF and WDGS increased milk production (37.39 vs. 36.92, 35.48, 35.71 kg\/day, for FF, WDGS and CTR diets, respectively) and reduced milk urea content (13.14 vs. 16.19, 15.58, 16.95 mg\/dL for FF, WDGS, and CTR diets, respectively). No effects of this association were found in the milk composition, acetic and propionic production, and fibre digestibility. These results suggest that the association of former foodstuff and wheat distillers\u2019 grains could be safely included in dairy cow rations to increase the sustainability of cow nutrition and improve milk production without impairing animal health, dry matter intake, and fibre digestibility.<\/jats:p>","DOI":"10.3390\/ani12243519","type":"journal-article","created":{"date-parts":[[2022,12,14]],"date-time":"2022-12-14T02:54:21Z","timestamp":1670986461000},"page":"3519","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":24,"title":["Combined Inclusion of Former Foodstuff and Distiller Grains in Dairy Cows Ration: Effect on Milk Production, Rumen Environment, and Fiber Digestibility"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7344-0686","authenticated-orcid":false,"given":"Ludovica Maria Eugenia","family":"Mammi","sequence":"first","affiliation":[{"name":"Department of Veterinary Medical Sciences, Alma Mater Studiorum\u2014University of Bologna, 40064 Bologna, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7806-4977","authenticated-orcid":false,"given":"Giovanni","family":"Buonaiuto","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medical Sciences, Alma Mater Studiorum\u2014University of Bologna, 40064 Bologna, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2800-202X","authenticated-orcid":false,"given":"Francesca","family":"Ghiaccio","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medical Sciences, Alma Mater Studiorum\u2014University of Bologna, 40064 Bologna, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1642-6722","authenticated-orcid":false,"given":"Damiano","family":"Cavallini","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medical Sciences, Alma Mater Studiorum\u2014University of Bologna, 40064 Bologna, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alberto","family":"Palmonari","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medical Sciences, Alma Mater Studiorum\u2014University of Bologna, 40064 Bologna, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2532-7240","authenticated-orcid":false,"given":"Isa","family":"Fusaro","sequence":"additional","affiliation":[{"name":"Faculty of Veterinary Medicine, University of Teramo, 64100 Teramo, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Valentina","family":"Massa","sequence":"additional","affiliation":[{"name":"Dalma Mangimi S.p.a., 12030 Marene, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrea","family":"Giorgino","sequence":"additional","affiliation":[{"name":"Dalma Mangimi S.p.a., 12030 Marene, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8109-2482","authenticated-orcid":false,"given":"Andrea","family":"Formigoni","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medical Sciences, Alma Mater Studiorum\u2014University of Bologna, 40064 Bologna, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,12,13]]},"reference":[{"key":"ref_1","unstructured":"European Feed Manufacturers Federation (FEFAC) (2022, September 15).
