Problems solved by technology

[0005] The purpose of the present invention is to: aim at the above-mentioned problems, to provide a compound bacterial agent, fermented feed and preparation method for fermenting straw feed. The present invention is based on the principle of "moderate degradation, limited fermentation", and the preparation method it provides It can not only solve the problems of lack of raw materials in cattle breeding industry in the prior art, difficult storage of feed, poor palatability, high preparation cost and high energy consumption, but also solve the problem of large pollution in the treatment of crop waste in the prior art, and the prepared beef cattle Straw fermented nutrient feed is extremely rich in nutrition, good palatability, easy to digest and absorb. After the beef cattle feed, it can increase the growth rate of the beef cattle, thereby improving the breeding efficiency, and greatly reducing the breeding cost

preparation example Construction

[0028] A method for preparing beef cattle straw fermented nutritional feed, characterized in that it comprises the following steps:

[0029] S1. Prepare a bacterial liquid from Rhodotorula lactosaccharomyces, Trichosporium viscoscensus, Cladosporium cladoides, Chlorococcus and Pediococcus pentosaceae in proportioning amounts, and set aside;

[0030] S2. Collecting crop stalks, which are pretreated and crushed to obtain crushed straws;

[0031]S3. Mix the bacterial liquid into the crushed straw according to the ratio, mix evenly, transfer to a fermentation environment for fermentation, and obtain the product after the fermentation is completed.

[0032] In the above method, in parts by weight, the composite microbial agent includes the following components: 1-7 parts of Rhodotorula lactis, 3-9 parts of Trichosporium viscosus, 10-16 parts of Cladosporium cladoides, chlorella 7-23 copies and 11-19 copies of Pediococcus pentosaceae.

[0033] Furthermore, the strains obtained by ...

Embodiment 1

[0042] The nutrient content of the fermented feed obtained by the fermentation of Example 1 and Comparative Examples 1-6 is as shown in Table 3:

[0043] The fermented feed nutrient content situation that table 3 embodiment and comparative examples obtain

[0044]

[0045] It can be obtained from Table 2 and Table 3: in Comparative Example 1, when there was a lack of Rhodotorula lactis, the crude protein and fat content in the fermented feed decreased significantly, thus indicating that the effect of a single type of yeast on degrading fermented stalks is not as good as that provided The effects of alkaline and acidic proteases on the degradation and fermentation of various yeasts; in comparative example 2, when lacking Cladosporium buddrosum, the cellulose content in the fermented feed was significantly increased, and the total energy was significantly decreased, which shows that the buds The introduction of Cladosporium cladoides can effectively improve the degree of degr...

Abstract

The invention discloses a complex microbial inoculant for fermenting a straw feed, the fermented feed and a preparation method, and the complex microbial inoculant comprises the following components in parts by weight: 1-7 parts of rhodotorula lactose, 3-9 parts of trichosporon viscosum, 10-16 parts of cladosporium cladosporioides, 7-23 parts of micrococcus and 11-19 parts of pediococcus pentosaceus. Based on the principle of moderate degradation and limited fermentation, the provided preparation method not only can solve the problems of lack of raw materials, difficult storage of feed, poor palatability, high preparation cost and high energy consumption in the cattle breeding industry in the prior art, but also can solve the problem of serious pollution caused by treatment of crop waste in the prior art; the prepared beef cattle straw fermented nutritional feed is extremely rich in nutrition, good in palatability and easy to digest and absorb, after the beef cattle eat the feed, the growth speed of the beef cattle can be increased, then the breeding efficiency is improved, and the breeding cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of feed preparation, in particular to a compound bacterial agent for fermenting straw feed, fermented feed and a preparation method. Background technique [0002] The application of biotechnology to straw fermented feed is a revolution in the feed industry. The use of straw fiber to replace part of the concentrated feed through biological treatment not only reduces the cost of breeding, improves the efficiency of breeding, but also enhances the immune function of ruminants, reduces the use of drugs, and makes animal husbandry products safer. However, in the prior art, the manufactured feed cannot effectively utilize the crop waste, and the storability and palatability of the prepared feed cannot be guaranteed. [0003] Chinese patent CN112586615A discloses a method for preparing beef cattle feed. The process steps are as follows: uniformly mix the fermented bacterial liquid, corn bran, rice bran and bone me...
