Problems solved by technology

[0003] Compared with the common Leucaena, Leucaena microphylla does not contain mimosin toxin, which can reduce the detoxification process steps in the processing and save production cost, but the content of neutral detergent fiber and acid detergent fiber in Leucaena microphylla is relatively high. High, reaching 39.70% and 34.20% respectively, after conventional fermentation treatment, it is still difficult to be completely digested by cattle, resulting in a negative effect on dry matter intake of cattle, affecting cattle's eating and absorption of other nutrients

Embodiment 1

[0026] A method for preparing cattle ecological fermented feed with purple elephant grass and Leucaena microphylla as substrates, comprising the following steps:

[0027] (1) Pretreatment of Leucaena microphylla: in parts by weight, chop 100 parts of tender stems and leaves of Leucaena microphylla into 1cm segments, put them into warm water at 35°C for 12min, and quickly remove them at -20°C after taking them out. Freeze in the environment for 24 hours, put it into the fermentation container after thawing, control the stacking thickness of Leucaena lobata to 4cm, mix 3 parts of extracellular enzymes, and then pass through N 2 and C0 2 The volume ratio is 1:20 N 2 / C0 2 The mixed gas was carried out for the first fermentation at 23°C for 20 hours to obtain the pretreated Leucaena lobata;

[0028] (2) drying of purple elephant grass: the purple elephant grass is air-dried to a moisture content of 68%, then cut into 1cm segments for subsequent use;

[0029] (3) Secondary ferm...

Embodiment 2

[0031] A method for preparing cattle ecological fermented feed with purple elephant grass and Leucaena microphylla as substrates, comprising the following steps:

[0032] (1) Pretreatment of Leucaena microphylla: in parts by weight, chop 100 parts of tender stems and leaves of Leucaena microphylla into 1.3cm segments, put them into warm water at 37°C for 15 minutes, and take them out quickly at -20°C Freeze in an environment for 26 hours, put it into a fermentation container after thawing, control the stacking thickness of Leucaena lobata to 4.5cm, mix 4 parts of extracellular enzymes, and then pass through N 2 and C0 2 The volume ratio is 1:22 N 2 / C0 2 The mixed gas was carried out for the first fermentation at 26°C for 25 hours to obtain the pretreated Leucaena lobata;

[0033] (2) drying of purple elephant grass: the purple elephant grass is air-dried to a moisture content of 69%, then cut into 1.5cm segments for subsequent use;

[0034](3) Secondary fermentation: in p...

Embodiment 3

[0036] A method for preparing cattle ecological fermented feed with purple elephant grass and Leucaena microphylla as substrates, comprising the following steps:

[0037] (1) Pretreatment of Leucaena microphylla: in parts by weight, chop 100 parts of tender stems and leaves of Leucaena microphylla into 1.5cm segments, put them into warm water at 40°C for 17min, and take them out quickly at -20°C Freeze in an environment for 30 hours, put it into a fermentation container after thawing, control the stacking thickness of Leucaena lobata to 5cm, mix 4 parts of extracellular enzymes, and then pass through N 2 and C0 2 The volume ratio is 1:27 N 2 / C0 2 The mixed gas was carried out for the first fermentation at 26°C for 28 hours to obtain the pretreated Leucaena lobata;

[0038] (2) drying of purple elephant grass: the purple elephant grass is air-dried to a moisture content of 70%, then cut into 1.4cm segments for subsequent use;

Abstract

The invention discloses a bovine ecological fermented feed using purple elephant grass and Leucaena microphylla as substrates, comprising the following raw materials: pretreated Leucaena microlea, purple elephant grass and lactic acid fermentation auxiliary bacteria; the bovine ecological fermentation The preparation of the feed includes the following steps: (1) pretreatment of Leucaena microphylla; (2) drying of purple elephant grass; (3) secondary fermentation: after mixing the raw materials evenly, put them into a fermentation container, and control the stacking of the materials thick, sealed, and fermented at room temperature for 35 to 45 days to obtain ecological fermented feed for cattle. The invention not only solves the problems of unbalanced nutrition and high content of neutral detergent fiber and acid detergent fiber in the fermented feed of single gramineous forage grass, but also fully retains the nutrition in purple elephant grass and Leucaena microleaf through secondary fermentation Substances and biologically active ingredients improve the palatability of leguminous forages, effectively reduce feeding costs, comprehensive nutritional value, good palatability, and easy-to-absorb cattle ecological feed.

Description

【Technical field】 [0001] The invention belongs to the field of feed, in particular to a bovine ecological fermented feed using purple elephant grass and Leucaena microphylla as substrates. 【Background technique】 [0002] At present, the development and application of fermented feed for cattle at home and abroad mostly use silage corn and crop straw as raw materials, with single nutritional quality and limited fermentation effect. Purple elephant grass is a perennial gramineous herb plant, clustered, with erect stems, plant height 250-360cm, purple stems and leaves, strong adaptability, fast growth, good regeneration, high grass yield, and crude protein content Up to 7-9%, rich in anthocyanins and other beneficial substances, drought-resistant, cold-resistant, acid-resistant, lodging-resistant, one-year planting can be used for many years, it is a high-quality forage for raising cattle, sheep, rabbits, fish, geese, etc. Leucaena microphylla is a small shrub of the leguminous...
