Embodiment Construction

[0017] The present invention will be further elaborated below in conjunction with specific embodiments.

[0018] The method for producing dairy cow feed by fermenting corn stalks comprises the following steps:

[0019] 1) Crush the dried corn stalks to 20 mesh or below to form corn stalk crushed material;

[0020] 2) Add dilute sulfuric acid with a mass concentration of 7-9% to the crushed corn stalks at a weight ratio of 1:20 and mix and react for 70-74 hours, then use the temperature at 100-120°C and the pressure at 6.86×10 -3 MPa high-temperature steam treatment for 40-60 minutes to complete the pretreatment process;

[0021] 3) Prepare nutrient solution, which is prepared by adding potassium dihydrogen phosphate, magnesium sulfate, ammonium sulfate and calcium chloride into deionized water and can be used after high-temperature sterilization at 120-125°C. Among them, each group The contents of potassium dihydrogen phosphate are 0.1-0.3 mg / mL, magnesium sulfate 0.1-0.3 mg...

Abstract

A method for producing a milk cow forage by utilizing corn straw for fermentation comprises: crushing dried corn straw, performing pretreatment, adding a nutrient solution into the corn straw crushed material subjected to pretreatment, mixing with stirring, and inoculating with a fermentation bacteria liquid to perform fermentation to obtain the finished product, wherein the pretreatment comprises dilute sulfuric acid processing and high-temperature steam processing. The fermentation corn straw forage provided by the invention has the advantages of comprehensive nutrition, good color, mellow sour fragrance and good palatability; the food consumption of milk cows is substantially improved; also beneficial microbes in the forage help to improve the survival environment of rumen microbes, adjust growth and breeding of microbes and enable the rumen microbes to be in a normal rapid development status, so that the milk cow health is guaranteed by guaranteeing the health of the rumen microbes; and also the forage helps to provide immunologic substances for milk cows, so that the anti-stress capability and the disease resistance of milk cows are improved.

Description

technical field [0001] The invention relates to the field of feed preparation by fermenting plant stalks, in particular to a method for producing dairy cow feed by fermenting corn stalks. Background technique [0002] Feeding dairy cows with fermented corn stalks has some small-scale applications in China. However, due to the existence of cellulose microcrystalline structure in corn stalks and the enveloping and bonding effect of the hemicellulose-lignin layer on cellulose, it is difficult for water to penetrate, cellulase cannot fully contact with the matrix, and the action is slow, which affects the cellulose. The enzymatic hydrolysis rate, cow digestibility and bacterial protein conversion rate. At the same time, factors such as high production cost of cellulase, immature production technology, and low enzymatic hydrolysis efficiency also affect the utilization of cellulose. In the study of fermented corn stalks, the single strain used for production has incomplete enzy...
