Problems solved by technology

Due to the nutritional limitation factors of the corn stalk feed mentioned above, the feed intake of the straw feed and the digestibility of nutrients by the livestock are seriously affected, thereby restricting the performance of the animal production performance. Therefore, it is necessary to scientifically use the corn stalk to feed the livestock, It is necessary to find the correct and effective way to improve the nutritional value of corn stalks. This way is the comprehensive pretreatment of corn stalks and microbial fermentation

Embodiment 1

[0025] A kind of production method of biological protein feed, its specific operation steps are:

[0026] Step 1. Pass the corn stalks through a straw grinder to crush them into particles that can pass through a 20-mesh sieve, and set aside;

[0027] Step 2: Treat the crushed straw particles with hot and humid steam for 30 minutes in an orbital autoclave at a temperature of 100° C., and set aside;

[0028] Step 3. According to the mass ratio of water and straw granules treated with hot and humid steam as 1:1, add water to the straw granules that have been treated with hot and humid steam, and mix well to obtain mixture A; then inoculate and expand the culture in the obtained mixture A The final brown rot fungus, the inoculum amount is 1% of the mixture mass; then, at a temperature of 30°C, ferment for 2 days to obtain a one-step fermentation product, which is set aside;

Abstract

The invention relates to a biological protein feed and a production method thereof. The production method comprises: crushing corn straw into particles capable of being screened with a 20 mesh sieve, and adopting a rail type autoclave to carry out a moisture and heat steam treatment for 30 min at a temperature of 100 DEG C; adopting a two-step method to ferment, wherein Gloeophyllum trabeum is firstly inoculated to ferment, urea, magnesium sulfate and potassium dihydrogen phosphate are added to the obtained primary fermentation product, uniform mixing is performed, and Aspergillus niger, Aspergillus oryzae, Bacillus subtilis and Candida utilis are inoculated to carry out secondary fermentation; drying after completing the fermentation; and carrying out 40 mesh crushing to obtain the biological protein feed. According to the present invention, the biological protein feed production method has characteristics of simple process and low cost; with application of the produced biological protein feed to feed milk cows, the milk yield can be increased by more than 4.7%, and the milk protein content can be increased by more than 4.1%; and the produced biological protein feed is suitable for various types of high, medium and low-end milk cow farming customers, and can further be used for feeding other livestock and poultry including piglets, chickens, ducks, geese and other poultry.

Description

technical field [0001] The invention relates to a feed, in particular to a biological protein feed and a production method thereof. Background technique [0002] Lignocellulosic biological resources are the most renewable resources in the world. The annual output of the world is estimated to be 1×1010 tons, of which straw accounts for about 70% of the available biomass production. In China, the annual output of crop stalks is 8.42×108 tons, and it is increasing at a rate of 1.3%. Among the crop stalks, corn stalks account for the largest proportion, which is 24%. At present, the total amount of domestic straw is directly used as living fuel About 20% are used as fertilizer, about 15% of the total are used as fertilizer, about 15% are used as feed, about 2% are used as industrial raw materials, and the rest are discarded or directly burned about 33%. . This has caused a great waste of resources and environmental pollution: burning straw will cause air pollution; pushing str...
