Problems solved by technology

Fruits contain a lot of carbohydrates, vitamins, minerals, bioactive ingredients and dietary fiber, which can be used as feed for ruminants, but in the collection, storage and transportation of defective fruits, there will be mildew and deterioration. Defective fruit itself is also caused by disease. These factors have a certain poisonous effect on ruminants. Therefore, in order to successfully apply defective fruit to ruminant feed, it is necessary to develop a safe treatment process for defective fruit.
For example, defective fruit contains a large amount of acidic substances (malic acid), phenols, pectin, sugars and other substances. If they are directly fed in large quantities, it is easy to cause excessive rumen acidity and cause rumen acidosis.

Embodiment 1

[0031] Example 1 A preparation method for preparing ruminant fermented feed by using residual fruit

[0032] 1. Collect the inferior fruits (dropped apples), squeeze, and separate solid and liquid.

[0033] The fallen apples are brewed with clean water, dried under natural conditions, crushed by a crusher, and then squeezed by a screw extrusion dehydrator, and the juice is collected during the extrusion process. The pomace is used as the raw material substrate for solid-state fermentation, and the fruit juice is used for the cultivation of fermenting strains.

[0034] 2. Aspergillus niger seed preparation (solid-state fermentation seed production)

[0035] (1) Preparation of Aspergillus niger slant strains

[0036] Preparation of Aspergillus niger slant strain: peptone 5 g / L, yeast extract powder 2 g / L, glucose 20 g / L, magnesium sulfate 0.5 g / L, dipotassium hydrogen phosphate 1 g / L, pH adjusted to 6.4±0.2, Agar 20 g / L, dilute to 1L with water, sterilize at 121°C for 30 minu...

Embodiment 2

[0059] Example 2 Preparation of common strains and fermentation to prepare ruminant fermented feed

[0060] The apple pomace obtained by extrusion in Example 1 is used as the solid fermentation medium raw material, and the ruminant fermentation feed of apple pomace is prepared with Lactobacillus plantarum, yeast, Bacillus licheniformis as the fermentation strain, and the strain used in this method is also the commonly used strain of pomace fermentation. . The specific method is as follows:

[0061] Mix apple pomace, palm meal, wheat bran, corn germ powder, light calcium carbonate, and glutamic acid residue according to a certain proportion, the specific proportion is apple pomace 55%, wheat bran 20%, soybean germ powder 10%, palm meal 5%, light calcium carbonate 0.2%, ammonium sulfate 0.8%, glutamic acid residue 5%. The mixed bacterial liquid and the above-mentioned solid fermentation substrate are fully mixed in the mixer according to the ratio of 20:1000, wherein each mill...

Embodiment 3

[0062] Example 3 Preparation of ruminant fermented feed without extrusion but using the strain of the present invention

[0063] The inferior fruit (dropped apple) was brewed with clean water, dried under natural conditions, and crushed by a crusher. According to the process of Example 1, the fermentation strain was inoculated and the ruminant fermented feed was prepared according to its fermentation process.

Abstract

The invention relates to a method and application for preparing ruminant fermented feed by using residual fruit, comprising the following steps: collecting residual fruit, crushing and extruding, and then separating solid-liquid; preparing fermentation strain; packing the mixed material through a baler Put it into the one-way valve breathing bag, transfer it to the culture room, and ferment it at 25-28°C for 3-5 days, and then the ruminant fermented feed prepared from the residual fruit can be obtained. The method presses the residual fruit, separates the pomace and the juice, can effectively reduce the moisture in the pomace, and indirectly reduces the sugar in the pomace, and can increase the utilization rate of the sugar by the microorganisms; the fermentation strain adopts two kinds of molds And the compound of two yeasts can effectively utilize the residual sugar in the pomace, decompose the macromolecular substances of the raw materials, and improve the digestion and utilization rate of the raw materials. The fermented feed prepared by the invention can reduce the content of lipopolysaccharide and increase the milk yield for acidosis and sub-health dairy cows, and the fermented feed has a higher pH and is easy to be popularized in commercial applications.

Description

technical field [0001] The present invention relates to the technical field of feed, in particular to a method and application for preparing ruminant fermented feed by utilizing residual fruit. [0002] technical background [0003] Defective fruit refers to the fruit that has been eliminated before the market or during the sale. It usually refers to the fruit that has fallen, and the quality or appearance is not particularly good. Although these fruits cannot enter the human table, they have high nutritional value. If they can be developed and used as feed, the waste of fruits can be greatly reduced. For example, for apples, the total output of apples in my country in 2021 will be 45 million tons, but this is the output of apples that enter the human table. It can reduce the feed pressure on our animal husbandry. Fruits contain a large amount of carbohydrates, vitamins, minerals, bioactive components and dietary fibers, which can be used as feed for ruminants. The defectiv...
