Abstract

The invention discloses a preparation method of a straw micro-storage feed, and is characterized in that the preparation method includes the following steps: (1) constructing a micro-storage cellar; (2) carrying out raw material pretreatment comprising sun-drying straw for 3-5 h to make the water content be 60%-70%, and cutting short into 2-3 cm; (3) preparing a fermentation agent: (4) weighing table salt according to 0.3% (weight percentage) of the straw dry basis amount, and evenly mixing into a fermentation bacterial powder; (5) laying a plastic film in the cellar, allowing the plastic film length to be 1-1.5 m higher than that the periphery of a cellar mouth; (6) sprinkling the crushed straw with the thickness of 20-30 cm at the bottom of the cellar, then sprinkling the prepared fermentation bacterial powder on the straw, and treading down with feet; and (7) allowing the micro-storage anaerobic fermentation time to be 7-8 days in summer, 10-12 days in spring and in autumn and 13-15 days in winter, checking whether the feed has a wine fragrance, and allowing for use. The nutritional value of the straw feed can be improved, and the feed has relatively high content of digestible proteins and has good palatability.

Description

technical field [0001] The invention relates to the field of animal husbandry feed, in particular to a method for preparing straw micro-storage feed. Background technique [0002] At present, with the vigorous development of my country's animal husbandry, the associated feed industry has also developed rapidly, but the problem of feed shortage is still prominent. In recent years, in addition to the traditional feed made of soybeans, soybean meal, corn and other raw materials , but also actively develop other types of feed, such as straw ammonification treatment can obtain feed with higher nutritional value, but the amount of urea required for ammoniation treatment is relatively large, and the cost is high. Another method is to use straw fermentation to prepare Roughage, due to its low preparation cost, has become one of the key development methods, but the current method of straw fermentation to prepare feed cannot effectively improve the nutritional value of straw feed, and t...
