Abstract Background Wheat distillers' grains (WDG) and seaweeds are recommended as alternative protein sources and enteric methane mitigators in dairy cow diets, respectively, but little is known about their impact on milk quality and safety. In the present study, 16 cows in four 4???4 latin squares were fed iso-nitrogenous diets (50:50 forage: concentrate ratio), with rapeseed meal (RSM)-based or WDG-based concentrate (230 and 205?g?kg?1 DM) and supplemented with or without Saccharina latissima. Results Replacement of RSM with WDG enhanced milk nutritional profile by decreasing milk atherogenicity (P?=?0.002) and thrombogenicity (P?=?0.019) indices and the concentrations of the nutritionally undesirable saturated fatty acids, specifically lauric (P?=?0.045), myristic (P?=?0.022) and palmitic (P?=?0.007) acids. It also increased milk concentrations of the nutritionally beneficial vaccenic (P?
