Problems solved by technology

[0002] With the development of agriculture, on the one hand, the livestock and poultry breeding industry is growing rapidly and requires a large amount of feed. However, the traditional feed formula is mainly based on grain. It is also getting higher and higher, which in turn increases the cost of farming and reduces the profit of farming
On the other hand, a large amount of crop stalks are discarded in vain, which not only causes waste but also pollutes the environment.
At present, there are the following problems in the method of microbial treatment of crop stalks: 1) The microorganisms used to process crop stalks are all single strains, and it is difficult to thoroughly improve the physicochemical shape of crop stalks, improve the palatability of the air passages, and increase the protein content.
2) Because there are many miscellaneous bacteria in the crop straw, it is difficult for the traditional microbial starter to become the dominant flora, and it is often contaminated by miscellaneous bacteria, especially easily polluted by bacteria that cause spoilage, resulting in feed deterioration
3) The microbial fermentation takes a long time and the efficiency is low

Embodiment 1

[0016] Use corn stalks as raw materials, crush them, adjust the moisture content to 40%, and treat them at 100MPa for 10 minutes, then add a starter to the raw materials at a ratio of 50:1 by weight between the raw materials and the starter, mix them evenly, and heat them at 40°C After fermentation for 2 hours, dry until the water content is lower than 10%, to obtain powdered pig feed; the starter is a mixture of photosynthetic bacteria, bacillus, lactobacillus, and yeast, and its weight ratio is 0.5:1:1: 1.5.

[0017] After testing, the conversion rate of organic matter can reach 98.5%, the C / N ratio is 9.7, and the effective bacteria number is greater than 10 6 cfu / g, organic matter content is 47%, and crude protein content is 15.8%. It is tested by the feed testing department and meets international feed production standards.

Embodiment 2

[0019] Use wheat straw as the raw material, crush it, adjust the moisture content to 50%, treat it at 150MPa for 25 minutes, then add the starter to the raw material according to the weight ratio of the raw material to the starter is 100:1, mix well, and heat it at 45°C After fermenting for 1.5 hours, dry until the water content is lower than 10% to obtain pig feed; the starter is a mixture of photosynthetic bacteria, bacillus, lactobacillus and yeast, and its weight ratio is 1:1.5:2:2 .

[0020] After testing, the conversion rate of organic matter can reach 98.2%, the C / N ratio is 8.9, and the effective bacteria number is greater than 10 6 cfu / g, the organic matter content is 51%, and the crude protein content is 15.2%. It has been tested by the feed testing department and has reached the international feed production standard.

Embodiment 3

[0022] Use cotton stalks as raw materials, crush them, adjust the moisture content to 45%, and treat them at 120MPa for 20 minutes, then add a starter to the raw materials at a ratio of 80:1 by weight of the raw materials and starters, mix them evenly, and heat them at 42°C After fermenting for 1 hour, dry until the water content is lower than 10%, to obtain pig feed; the starter is a mixture of photosynthetic bacteria, bacillus, lactobacillus and yeast, and its weight ratio is 0.8:1.2:1.5:1.8.

[0023] After testing, the conversion rate of organic matter can reach 98.6%, the C / N ratio is 9.4, and the effective bacteria number is greater than 10 6 cfu / g, organic matter content is 51%, and crude protein content is 15.0%. It has been tested by the feed testing department and has reached the international feed production standard.

Abstract

The invention provides a preparation method of a pig feed. The preparation method comprises the following steps: by taking crop straws as a raw material, crushing the raw materials; adjusting the moisture content to 40-50%; treating the raw material at 100-150Mpa for 10-25 minutes; then, adding a fermentation agent into the raw material in a proportion that the weight ratio of the raw material and the fermentation agent is (50-100): 1 and uniformly mixing the raw material with the fermentation agent; fermenting the mixture at 40-45 DEG C for 1-2 hours; and then drying the mixture till the moisture content is lower than 10% to obtain the pig feed. The fermentation agent is mixed bacteria of photosynthetic bacteria, bacillus, lactobacillus and saccharomycetes in a weight ratio of (0.5-1): (1-1.5): (1-2): (1.5-2). The preparation method takes short time, and the feed is hardly polluted by infectious microbes to be deteriorated.

technical field [0001] The invention relates to a method for preparing feed, in particular to a method for preparing pig feed. Background technique [0002] With the development of agriculture, on the one hand, the livestock and poultry breeding industry is growing rapidly and requires a large amount of feed. However, the traditional feed formula is mainly based on grain. It is also getting higher and higher, which in turn increases the cost of breeding and reduces the profit of breeding. On the other hand, a large amount of crop stalks are discarded in vain, which not only causes waste but also pollutes the environment. At present, there are the following problems in the method of microbial treatment of crop stalks: 1) The microorganisms used to process crop stalks are all single strains, and it is difficult to thoroughly improve the physicochemical shape of crop stalks, improve the palatability of the air passages, and increase the protein content. . 2) Because there ar...
