Problems solved by technology

[0006] To sum up, the hybrid mulberry tree has high protein content, rich in amino acids, vitamins, carbohydrates and trace elements and other nutrients, but its high tannin content leads to poor palatability, and the complex protein structure also makes it low in direct feeding digestion and utilization, seriously Limiting the application of hybrid mulberry tree in livestock and poultry feed
At present, silage and compound bacterial fermentation can improve the palatability and digestibility of hybrid mulberry trees to a certain extent, but the effect is not ideal, and the processing process takes a long time

[0090] Preparation of Lactobacillus plantarum P-8 bacterial agent

[0091] The activated Lactobacillus plantarum P-8 was inoculated into a 500ml Erlenmeyer flask equipped with 100ml of fermentation medium, cultured at 33°C for 24 hours, and the fermentation broth was collected to obtain the Lactobacillus plantarum P-8 seed solution.

[0092] Plantarum Lactobacillus P-8 seed liquid is inserted in the 500L fermenter that the fermentation medium of 200L is housed according to the inoculum size of 6% (volume ratio), at 33 ℃, cultivate 24 hours under the condition of 100rpm at stirring speed, collect All the cultured substances (fermentation liquid) in the fermenter were added with rice husk powder and dried at 50° C. to obtain Lactobacillus plantarum P-8 inoculum. The content of Lactobacillus plantarum P-8 in the Lactobacillus plantarum P-8 bacterial agent is 1×10 11 CFU / g.

[0110] Example 1 Application of hybrid mulberry fermented feed for ruminants on dairy cows

[0111] 1. Preparation of hybrid mulberry fermented feed for ruminants

[0112] In this example, the raw material composition with hybrid mulberry as the main component was fermented with compound bacterial agent and / or compound enzyme to obtain three kinds of hybrid mulberry fermented feed for ruminants, which were respectively named as bacteria-enzyme synergistic fermentation of hybrid mulberry for ruminants Fermented feed, bacteria fermented alone hybrid mulberry fermented feed for ruminants and enzyme alone fermented hybrid mulberry fermented feed for ruminants. The specific preparation method is as follows:

[0145] Example 2 Application of hybrid mulberry fermented feed for ruminants on beef cattle

[0146] The feed obtained by adding the bacteria and enzymes described in Example 1 to ferment the hybrid mulberry tree fermented feed for ruminants in the basal diet was used as a diet to feed beef cattle. The formula was adjusted according to the nutritional requirements of animals, and the reference feeding amounts of beef cattle in different physiological stages are shown in Table 4.

Abstract

The invention discloses a hybrid broussonetia papyrifera fermented feed for ruminants and a preparation method and application thereof. The method firstly discloses the method for preparing the hybridbroussonetia papyrifera fermented feed for the ruminants. The method comprises the steps of: inoculating a composite bacterium agent and a composite enzyme into a raw material composition using hybrid broussonetia papyrifera as a main ingredient, and fermenting to obtain a fermentation product, wherein the fermentation product is the hybrid broussonetia papyrifera fermented feed for the ruminants. The invention further discloses the hybrid broussonetia papyrifera fermented feed for the ruminants, which is prepared by the method. According to the invention, compared with a conventional fermentation technology, a bacterium-enzyme synergistic fermentation technology of the composite bacterium agent and the composite enzyme gives consideration to microbial nutrition requirements, animal nutrition requirements and intestinal microecological balance, shortens the fermentation time, reduces the tannin content of the hybrid broussonetia papyrifera, improves the palatability and digestibility,promotes food intake and gastrointestinal digestion, improves the production performance, the milk quality and the meat quality of the ruminants, and enhances the immune function of the ruminants.

Description

technical field [0001] The invention relates to the technical field of fermented feed, in particular to a hybrid mulberry fermented feed for ruminants and a preparation method and application thereof. Background technique [0002] With the development of society and the continuous improvement of people's living standards, the demand for beef, mutton, milk and dairy products in daily life is increasing. Therefore, the demand for protein feed and high-quality roughage is also increasing year by year. However, the shortage of feed resources has always been a major problem in China's aquaculture industry, which needs to rely on imports for a long time. At present, the price of soybean meal and forage has risen, and the import tariffs of various feeds and fermented feeds have increased, which has brought severe challenges to saving costs and increasing efficiency in cattle and sheep farming. [0003] As a high-protein woody feed, hybrid mulberry tree has a protein content as hig...
