Problems solved by technology

According to statistics, about 200,000 to 300,000 tons of feather shaft scraps can be collected and utilized in my country every year, and less than 20,000 tons are used for feed after processing. Most of the feathers and animal hair have not been rationally utilized.
The puffing method has not been popularized and applied in my country due to large investment, high cost and low production efficiency.

Embodiment 1

[0045] Crush the crop corn stalks, the length is 5cm, mix the crushed corn stalks with chicken feathers, according to the mass ratio of corn stalks and chicken feathers is 10:1, the mixture is sent into the steam explosion tank for steam explosion treatment, at a pressure of 0.8MPa Maintain the temperature for 20 minutes, and obtain steam explosion materials after treatment. After the steam explosion material and the bran are mixed in a mass ratio of 7:1, add (NH 4 ) 2 SO 4 5%, glucose 2%, H 3 PO 4 1%. , adjust the water content of the mixture to 40%, PH to 4.0, inoculate 30% of the filamentous fungus Trichoderma koningiiz at 28°C for 7 days, then inoculate 30% of Candida utilis at 28°C for 5 days, and finally inoculate 30% lactic acid bacteria Lactobacillus plantarum were cultured at 28°C for 5 days.

[0046] After the fermentation, the mixture is dried at 60°C until the water content is less than 12% to obtain the feed product. Using the Kjeldahl method to determi...

[0048] Crush the wheat straw of the crops, the length is 5cm, mix the crushed wheat straw with chicken feathers, according to the mass ratio of wheat straw to chicken feathers is 5:1, send the mixture into the steam explosion tank for steam explosion treatment, at a pressure of 1.5MPa Maintain the temperature for 10 minutes, and obtain the steam explosion material after treatment. After the steam explosion material and the bran are mixed in a mass ratio of 7:1, add (NH 4 ) 2 SO 4 5%, glucose 2%, H 3 PO 4 1%. , adjust the water content of the mixture to 40%, PH to 4.0, inoculate 30% of the filamentous fungus Trichoderma koningiiz at 28°C for 7 days, then inoculate 30% of Candida utilis at 28°C for 5 days, and finally inoculate 30% lactic acid bacteria Lactobacillus plantarum were cultured at 28°C for 5 days.

[0049] After the fermentation, the mixture is dried at 60°C until the water content is less than 12% to obtain the feed product. Use the Kjeldahl method to mea...

Embodiment 3

[0051] Crush the crop rice stalks with a length of 5cm, mix the crushed rice stalks with chicken feathers, and send the mixture into a steam explosion tank for steam explosion treatment according to the mass ratio of rice stalks and chicken feathers at a pressure of 2MPa. Maintain it for 8 minutes, and obtain steam explosion material after treatment. After mixing the steam explosion material and the bran in a mass ratio of 8:1, add (NH 4 ) 2 SO 4 3%, glucose 1%, H 3 PO 4 1%. , adjust the water content of the mixture to 50%, PH to 4.5, inoculate 20% of the filamentous fungus Trichoderma koningiiz at 28°C for 7 days, then inoculate 20% of Candida utilis at 28°C for 5 days, and finally inoculate 30% lactic acid bacteria Lactobacillus plantarum were cultured at 28°C for 5 days.

[0052] After the fermentation, the mixture is dried at 60°C until the water content is less than 12% to obtain the feed product. Using the Kjeldahl method to determine the crude protein content...

Abstract

The invention provides a preparation method for feed. The preparation method comprises the following steps: (a) mixing crushed crop straws and livestock feathers to obtain a mixture; (b) carrying out steam explosion treatment on the mixture to obtain a steam explosion material; (c) mixing the steam explosion material obtained by the step (b) with bran and nutrition liquid to obtain a culture medium; sequentially inoculating filamentous fungi, candida utilis and lactic acid bacteria on the culture medium and fermenting; (d) drying the culture medium fermented in the step (c) to obtain the feed. According to the preparation method for the feed provided by the invention, the feed is high in production efficiency, abundant in nutrient substances and easy to digest by livestock.

Description

technical field [0001] The invention relates to the field of biological fermentation, more specifically, to a preparation method of feed. Background technique [0002] With the increase of population and income, the food structure of Chinese residents has been greatly improved, and the demand for edible animal products has grown rapidly. Therefore, the rapid increase in the consumption of animal foods such as meat, eggs, and milk will inevitably lead to an increase in the demand for feed . At the same time, my country's cultivated land resources are constantly decreasing, and natural grasslands are constantly disappearing. How to make more reasonable and effective use of existing precious resources is particularly important. [0003] my country has a very long history of using straw as feed, and crop straw mainly includes wheat straw, rice straw, corn straw, sorghum straw and soybean straw. Different types of straw used for livestock feed have very different nutritional co...
