Embodiment Construction

[0027] A method for preparing crop straw feed by combining biology and extruding technology, comprising the following specific steps:

[0028] (1) Crushing:

[0029] Remove unusable impurities and spoilage components from the crop straw, and use a hammer mill for crushing, with a crushing length of 1-3cm;

[0030] (2) Chemical pretreatment:

[0031] According to the weight ratio of 100:5:3, the crop stalks through pulverization are mixed with urea and calcium hydroxide, and put into an airtight container for compound treatment, and anaerobic fermentation is carried out for 20 days;

[0032] (3) Biological treatment:

[0033] ①. Preparation of fermented liquid:

[0034] Stir and mix water, sugar and urea according to the mass ratio of 100:4:12, add activated white putrefying fungus strains, and make a fermentation liquid;

[0035] ②. Fermentation treatment:

[0036] Lay 20-30cm thick step (2) crushed material on the bottom of the cement pool, spray the fermentation liquid ...

Abstract

The invention discloses a method for preparing crop straw feed by combined biological and expansion techniques; in the invention, crushed straw is subjected to combined ammonization and alkalization treatment via urea and calcium hydroxide, so that expansion effect can be improved, digestibility of fibers is improved and the content of crude protein is effectively increased; through biological fermentation, straws may fully bear the microbial action, and crude fibers are effectively degraded and may be biologically converted into mass physiologically active substances, such as bacterial protein and amino acids, and nutritional value is improved; expanding is finally performed, and therefore, eggs, molds, viruses and the like in straws can be killed thoroughly, and spread of livestock diseases due to feed factors is blocked; glucose, maltose and the like can be generated by expansion, so that straws are more palatable.

Description

technical field [0001] The invention relates to a feed processing method, in particular to a method for preparing crop straw feed by combining biology and puffing technology. Background technique [0002] According to estimates, my country's total straw output in 2005 reached about 840 million tons, and there is a growing trend. The three major crop straws, rice straw, corn straw and wheat straw, are still the main straw types. my country produces a large amount of straw, but it cannot be rationally utilized. According to rough statistics, only 15%-20% is used as feed for livestock and poultry, and more than 80% is burned, weathered, and mildewed, resulting in a large amount of waste of resources and environmental pollution. At the same time, with the rapid development of animal husbandry, the contradiction of "human and animal competition for food" has become increasingly serious, and the problem of feed shortage has become more prominent. [0003] Straw feed is a roughage...
