The application relates to a microbial preparation passing through the rumen, a preparation method and application thereof. The microbial preparation passing through the rumen comprises microbial powder and a coating material coated on the surface of the microbial powder. The coating material comprises protective fat. The total weight of fatty acids in the microbial preparation passing through the rumen is 100%, the fatty acids comprise 70wt%-80wt% of palmitic acid and stearic acid, <=9wt% of oleic acid, 5wt%-15wt% of polyunsaturated fatty acids and a residual amount of non-target fatty acids, the mass ratio of the palmitic acid to the stearic acid is 1:1-2:1, the polyunsaturated fatty acids are selected from at least one of docosahexaenoic acid, eicosatetraenoic acid and eicosapentaenoic acid, and the mass ratio of the microbial powder to the protective fat is 2:3-3:2. The microbial preparation passing through the rumen described in the application is used as a feed additive for feeding ruminants such as cows, and can realize the dual improvement of the production performance of the cows and the nutrition strengthening of the milk.
