This invention belongs to the field of dairy goat feed technology, specifically relating to a total mixed ration (TMR) for dairy goats containing fresh oat hay, its preparation method, and its application. The invention involves chopping fresh oat hay, sequentially spraying it with a functional oil-based compound emulsion and an organic acid salt compound preservative solution, followed by static adsorption and mixing treatment, and then gradient mixing with dry-based raw materials to obtain the TMR. This invention is the first to achieve the direct use of high-moisture fresh oat hay in TMR without fermentation. It utilizes the cell wall fiber network of fresh oat hay as a natural carrier for functional oils, allowing the oils to penetrate into the fiber pores through static adsorption, forming a stable physical encapsulation structure and effectively reducing the rumen hydrogenation rate of polyunsaturated fatty acids. The invention employs a low-starch, high-slow-release fiber gradient energy supply design, combined with the organic acid salt compound preservative solution, to achieve synergistic effects in feed preservation, oil protection, and rumen health regulation.

The application discloses a method for improving gas production performance of straw and pig manure mixture dry biogas fermentation based on multi-factor cooperation, which comprises the following steps: mixing pig manure and straw at a ratio of 1:1 as the best feed substrate according to total solids, adopting semi-continuous dry biogas fermentation process, feeding the substrate into a biogas fermentation reactor, inoculating anaerobic sludge domesticated by pig manure, controlling the total solid concentration of the feed substrate to be 20%-30%, controlling the hydraulic retention time to be 25-45 days, feeding air into the fermentation process for air stirring, controlling the stirring intensity to be 33.3-66.7 mL / (L.min), and stirring once a day for 1 minute each time. The straw and pig manure mixture dry biogas fermentation gas production performance can be effectively improved through the synergistic effect of the optimized raw material ratio, the total solid concentration of the feed, the hydraulic retention time and the air stirring intensity.
