The invention discloses a corn bran bacterial protein fermented feed and a preparation method thereof. The preparation method of the corn bran bacterial protein fermented feed disclosed by the invention comprises the following steps: adding a primary fermentation inoculant into a fermentation material mainly composed of corn bran for primary fermentation to obtain a primary culture product; adding a secondary fermentation inoculant into the culture product for secondary fermentation to obtain a secondary fermentation product, the secondary fermentation product is the corn bran bacterial protein fermented feed; the active ingredients of the primary fermentation inoculant are aspergillus niger, bacillus subtilis and saccharomyces cerevisiae; the active ingredient of the secondary fermentation inoculant is lactobacillus buchneri. The corn bran bacterial protein fermented feed and the preparation method thereof have a wide application prospect.

The invention discloses a low-concentrate type fermented total mixed ration (TMR) for dairy cows and a preparation method thereof. The TMR is prepared by the following steps of: (1) mixing the following materials in part by mass to obtain a mixture: 15 to 20 parts of straw, 4 to 8 parts of fodder grass, 6 to 12 parts of protein feed, 25 to 30 parts of energy feed, 3 to 6 parts of minerals and molasses, 40 to 45 parts of food processing by-products and 0.5 to 1 part of premix compound of trace elements and vitamins; (2) adjusting the moisture content of the mixture of the step (1) to be between 40 and 50 percent; and (3) sealing and fermenting the mixture of the step (2) for more than 14 days to obtain the ration for the dairy cows. The TMR of the invention has the following advantages of:low cost; complete nutrition and homogeneous components to avoid animal picky eaters and significantly improve the production performance of animals; and high aerobic stability. The low-concentrate type fermented total mixed ration for the dairy cows opens up a new technique and an effective way for efficient utilization of the resources of the straw and the food processing by-products, and has important practicability and application promotion values.

The invention discloses mixed silage of Alhagi sparsifolia Shap. in an initial bloom stage and Medicago Sativa in an initial bloom stage and a preparation method thereof, and relates to mixed silage of two kinds of leguminous forages and a preparation method thereof. The method comprises the following steps of: harvesting the Alhagi sparsifolia Shap. in the initial bloom stage and the Medicago Sativa in the initial bloom stage; mincing the two kinds of fresh forages; uniformly mixing 30 to 70 weight percent of Alhagi sparsifolia Shap. and 30 to 70 weight percent of Medicago Sativa; filling, compacting, and sealing; and fermenting at normal temperature and preserving. By the method, the problems that thorn-shaped pedicels of the Alhagi sparsifolia Shap. affect the palatability of the feed,the soluble sugar content of the Medicago Sativa is low, the buffer energy is high, and the direct ensiling is difficult are solved, and the silage with high protein content and high quality is obtained; and the silage has high aerobic stability, can retain the nutritional characteristics of green and juiciness of the Alhagi sparsifolia Shap. and the Medicago Sativa for a longer time, and is environment-friendly, additives are not required, ensiling equipment is simple, and the method is easy to operate.

A method for treating silage to enhance the aerobic stability by increasing the fermentation and stabilization of silage by inhibiting growth of microorganisms selected from yeasts, molds and spore-forming bacteria and permitting earlier aerobic exposure is disclosed. The method comprises treating silage or feed with a composition comprising Lactobacillus buchneri strain LN7125, or Lactobacillus brevis strain LB5328, or Lactobacillus brevis strain LB7123, and mixtures or a mutant thereof which retains the silage preservative activity of LN7125, LB5328, or LB7123, or the antimicrobial components produced thereby. The strains of Lactobacillus buchneri and Lactobacillus brevis disclosed in the invention have been purified and isolated and have been found to improve aerobic stability of silage allowing earlier aerobic exposure post ensiling than is presently practiced
