Problems solved by technology

However, for straw, the combination of lignin and cellulose is relatively tight, which constitutes a resistance barrier to enzymatic hydrolysis, causing the active center of the enzyme to fail to effectively combine with lignin or cellulose, resulting in low enzymatic reactions and straw decomposition. Not only the cost is high, straw resources also cause waste

Abstract

The invention discloses a method for preparing modified soybean straw pig fodder and the pig fodder prepared by means of the method. The method comprises the following steps that 1, soybean straw, soybean hulls, soybean meal, soybean oil and soybean bran are placed in an ultrafine crusher to be crushed into fine powder with the particle size of 500-600 mesh; 2, a modifier is added to the fine powder in the step 1, wherein the modifier is prepared from, by weight, yeast, ceriporiopsis subvermispora, phanerochaete chrysosporium, variegated coriolus versicolor, pleurotus ostreatus, hirschioporuslacteus and coriolopsis gallica; a mixture is formed after the addition of the modifier and poured into a fermentation tank, water is added for stirring, and the moisture content of the mixture is controlled within 15%-30%; 3, after the water is added for stirring and the temperature rises to 30-40 DEG C, and fermentation is conducted for 12-20 hours; 4, the fermented material in the step 3 is taken out and placed in a granulation dryer for drying granulation, and the finished pig fodder is obtained after the granulation is completed.

Description

technical field [0001] The invention relates to the field of pig feed, in particular to a method for preparing modified soybean straw pig feed and the prepared pig feed. Background technique [0002] my country is a big pork consumption country. Pig breeding is inseparable from feed. In general pig raising costs, feed costs account for about 70%. Therefore, the cost of breeding is relatively high. my country is also a large agricultural country, and a large amount of straw is produced during summer harvest, autumn and winter. According to statistics, more than 700 million tons of straw can be produced every year. However, in recent years, crop straw, especially soybean straw, has become a new source of rural pollution. A large amount of straw has nowhere to digest, and farmers can only burn it in the field, producing a lot of thick smoke, making smoke, particulate matter and other pollutants in the air The concentration of straw increases sharply, which is not conducive to...
