Embodiment 1

[0015] Embodiment 1: a kind of method utilizing grape pomace to prepare fermented feed comprises the following steps:

[0016] The first step, the configuration of the first-stage fermentation medium: take a certain amount of grape pomace, rapeseed meal, urea, ammonium nitrate, calcium carbonate, potassium dihydrogen phosphate and magnesium chloride, and mix the above raw materials evenly, wherein the first-stage fermentation The weight percentage of each raw material in the medium is: grape pomace 95%, rapeseed meal 3%, urea 0.1%, ammonium nitrate 0.5%, calcium carbonate 0.4%, potassium dihydrogen phosphate 0.5%, magnesium chloride 0.5%;

[0017] The second step, the first-stage fermentation: add a starter consisting of Aspergillus oryzae and Neurospora crassa to the first-stage fermentation medium, so that the total number of live bacteria of Aspergillus oryzae and Neurospora crassa in the medium is 2×10 8 cfu / (kg medium), fermented at 25°C for 2 days;

Embodiment 3

[0029] Embodiment 3: animal feeding experiment

[0030] In a large pig farm in Tongliang District, Chongqing, 200 fattening pigs with ages of about two months, relatively close age difference, and basically the same growth condition were selected and randomly divided into 5 groups, 40 pigs in each group. 5% of the total mass of the test samples were added to the pig feed, in which group 1 was the blank control group, and 5% of fresh grape pomace was added to the feed; groups 2 to 3 were comparative test groups, and 5% The obtained grape marc fermented feed of comparative test example 1, 2; Group 4~5 is experimental group, adds the grape marc fermented feed that 5% embodiment 1, 2 makes respectively, feeds and observes 20 days, measures Body weight change and growth situation before and after feeding, the specific results are shown in Table 1:

Abstract

The invention relates to a method of preparing a fermented feed with grape residues as a main raw material through multi-stage fermentation. The feed not only basically satisfies protein demand of animals fed thereon, but also has health-caring effects of improving intestinal tract health and enhancing immunity of the animals. With the grape residues as a raw material, the feed is low in cost and has wide raw material source, achieves comprehensive utilization of the grape residues, and has excellent ecologic and social benefits.

Description

technical field [0001] The invention relates to the field of feed, in particular to a method for preparing fermented feed using grape pomace. Background technique [0002] Studies have found that grape pomace contains many important nutrients, and grape pomace has high nutritional value. According to its nutritional characteristics, it can be used as animal feed raw material after treatment. This idea has been recognized by many scholars and experts. The most widely used utilization of by-products after grape processing is to use grape residues directly as feed and add them to animal diets to reduce feed costs and alleviate feed shortages. However, this extensive use method cannot meet the needs of modern college animal husbandry. The demand for rapid development cannot maximize the nutritional value of grape marc. In addition, due to the high water content of fresh pomace, it is easy to spoil and deteriorate, which not only pollutes the environment but also causes waste o...
