Embodiment 1

[0013] Cut the corn stalks into short pieces and crush them into 3-4 cm long, mix the apple juice concentrate and corn stalks in a mass ratio of 3:7, control the water content at about 65%, and inoculate yeast, Lactobacillus plantarum and Lactobacillus acidophilus at the same time , sealed in the cellar, and fermented at 23°C for 40 days to open the cellar for use. After fermentation, the pH value can reach below 4.5, which is suitable for preservation.

Embodiment 2

[0020] Cut the corn stalks to 3-4 cm long, mix the apple juice concentrate and corn stalks (cut the stalks to 3-4 cm long) in a mass ratio of 4:6, keep the water content at about 70%, and inoculate at the same time Yeast, Lactobacillus plantarum, and Lactobacillus acidophilus are sealed in cellars and fermented at 24°C for 42 days before being opened for use. After fermentation, the pH value is 4.5, which is suitable for preservation.

[0027] Cut the corn stalks to 3-4 cm long, mix the apple juice concentrate and corn stalks (cut the stalks to 3-4 cm long) in a mass ratio of 5:5, control the water content at about 75%, and put it in a cellar Sealed and fermented at 25°C for 45 days before opening the cellar for use. After fermentation, the pH value is 4.5, which is suitable for preservation.

Abstract

The invention relates to the feed field, in particular to a method for producing a straw fermented feed by taking concentrations produced by the membrane filtration process in the process of producing apple juice as additives. The method comprises the following steps: 1) mixing the juice concentrations and straws based on the mass ratio of 3:7-5:5 and controlling the moisture content between 65-75% after mixing; 2) stirring the mixture uniformly and fermenting the mixed materials; 3) sub-packing the fermentation product which can be used as a ruminant feed. The apple juice concentrations and straws are mixed and fermented according to certain proportion; the nutrient contents and characteristics of the two raw materials have strong complementarity; the two raw materials are waste materials in the production and can be regarded as roughage feeds for cultivating ruminants after being processed by the method.

Description

technical field [0001] The invention relates to the field of feed, in particular to a method for producing straw fermented feed by using apple juice concentrate and straw as raw materials. Background technique [0002] Apple juice concentrate is the product of the membrane filtration process in apple juice production. Its main components are pulp and macromolecular substances in juice. It is rich in nutrients. In the current juice production, the output ratio is 10% of the fresh apple processing. The apple juice concentrate is also rich in vitamins, fruit acids, pectin, and fructose, which is beneficial to the absorption and utilization of microorganisms in the fermentation process of straw, and improves the digestibility of straw. The COD (chemical oxygen demand) of apple juice concentrate is as high as 10 5 PPM, the existing treatment method is treated as industrial wastewater. [0003] my country is rich in straw resources, and the main application methods are: as feed ...
