Abstract
The present invention discloses a production method of straw feed preventing fungi and bacteria. The production method consists of the following steps: (1) straws are collected, rotten and spoiled parts are removed, then the straws are dried and the dried straws are stored in a dry and ventilated environment; (2) the straws are crushed using a crusher with sieve diameters of 1-5 mm and the crushed straws are sterilized at 100-130 DEG C for 10-60 min via a crawler-type high-temperature chamber; (3) fungicides and bactericides are added into the sterilized straws, and the mixture is stirred evenly at a speed of 300-500 r/min; (4) the straws added with the fungicides and bactericides are added into a granulator to be pressed into straw granules with diameters of 0.3-0.5 mm and lengths of 0.5-1 mm, and the straw granules are vacuum packed and stored. By the twice sterilization, the viabilities of the fungi in the straw feed granules are maximally reduced, which provides necessary technical basis for the development of using the abundant crop straws to produce livestock feed granules. The method is simple in production process, easy to operate, and easy to promote. The obtained products have relative high added values and good application prospects, and can be used to feed pigs, cattle, sheep, horses and other livestock.
