Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with examples, but the embodiments of the present invention are not limited thereto.

[0028] Part 1: Orthogonal experiment to obtain and verify the optimal formula

[0029] 1 Materials and methods

[0030] 1.1 Materials

[0031] Mulberry leaves: from the Huadu base of Guangdong Academy of Agricultural Sciences. The measured dry matter, crude protein, and crude fat contents were 30.50%, 23.67%, and 2.52%, respectively, and the tannin content was 13.21g / kg.

[0032] Pediococcus cellar (CGMCC1.3787) was purchased from the China General Microorganisms Culture Collection and Management Center, and Bacillus licheniformis and Corynespora portuguese were both from the Institute of Animal Science, Guangdong Academy of Agricultural Sciences.

[0033] 1.2 Main reagents and instruments

[0034] MRS broth medium, nutrient broth medium, and potato dextrose medium were purchased from Guangdong Huankai ...

Abstract

The invention belongs to the technical field of agriculture, and discloses a mulberry leaf fermented feed which is obtained by performing solid state fermentation on mulberry leaves and bran in the presence of composite strains, and the weight ratio of the mulberry leaves to the bran is 7: 3-10: 1; the composite strain is a combination of pediococcus cellicola and bacillus licheniformis; the inoculation amount of the composite strains in the mulberry leaves and the bran is 4.5*10<6>-9*10<6> CFU. According to the mulberry leaf fermented feed disclosed by the invention, the strain selection and the ratio of the mulberry leaves to the bran have positive influences on the contents of tannin and crude protein, and compared with a non-fermented feed or a fermented feed by adopting a scheme of carrying out solid state fermentation with other strains, the mulberry leaf fermented feed disclosed by the invention has obvious advantages.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a fermented mulberry leaf feed and a preparation method thereof. Background technique [0002] Mulberry leaves grow fast, and the annual output can reach 20 tons / ha. However, only 1% to 3% of mulberry leaf resources are available, and the remaining old mulberry leaves have a huge output [1] . A large amount of mulberries and by-products were burned on the spot, which not only caused waste, but also caused environmental pollution. Making full use of the waste mulberry leaf resources in the sericulture industry, reducing waste of resources and increasing sources of feed raw materials is an efficient and healthy resource utilization strategy, which is of great significance to the sustainable development of my country's feed industry and animal husbandry. [0003] Mulberry has the characteristics of wide planting, large range, stress resistance and ecological envir...
