Milk metagenome Raw sequence reads

Grape stalks (GS) of 3 red grape varieties were collected from a local wine cellar: Lagrein, Cabernet Sauvignon and Merlot. Grape stalks were ground and analyzed for their microbial and chemical safety. Following the results obtained, 3 Holstein cows, already fed with hay and concentrates, were selected by a local dairy farm, for the test of daily supplementation with GS at 2% DM of the diet. The study consisted of a one-week control period (CTRL), when no GS supplementation was added to the cows' diet, followed by a week of GS supplementation, for a total of 7 weeks of experimental study (4 CTRL and 3 GS diet weeks). Every week, individual milk samples were collected on the last day of the week and analysed for microbiologica composition.
