Embodiment 1

[0024] The technical scheme that present embodiment takes is: sweet sorghum and alfalfa mixed silage are made by following steps:

[0025] (1) Harvesting of raw materials: sweet sorghum is harvested at the stage of milk maturity, and alfalfa is harvested at the early flowering stage (5% of alfalfa blooms);

[0026] (2) Chopping: Cut sweet sorghum and alfalfa into 2-4cm long sections respectively;

[0027] (3) Mixing: 20% by weight sweet sorghum and 80% alfalfa are evenly mixed to make filling material.

[0028] (4) Filling and compacting: Fill the above-mentioned fillers in layers in the silo, the thickness of each layer is 50-60cm, and compact them layer by layer, so that the density of the filler after compaction reaches 650-750g / L. The final compacted filling material is 30cm higher than the silage pit mouth.

[0029] (5) Sealing: Cover the silage pit completely with a thick plastic cloth, and the plastic cloth for sealing the mouth of the silage pit is 50 cm more than th...

Embodiment 2

[0032] The technical scheme that present embodiment takes is: sweet sorghum and alfalfa mixed silage are made by following steps:

[0033] (1) Harvesting of raw materials: sweet sorghum is harvested at the stage of milk maturity, and alfalfa is harvested at the early flowering stage (10% of alfalfa is blooming);

[0034] (2) Chopping: Cut sweet sorghum and alfalfa into 2-4cm long sections respectively;

[0035] (3) Mixing: mix 40% sweet sorghum and 60% alfalfa evenly by weight to make filling.

[0036] (4) Filling and compacting: Fill the above-mentioned fillers in layers in the silo, the thickness of each layer is 50-60cm, and compact them layer by layer, so that the density of the filler after compaction reaches 650-750g / L. The final compacted filling material is 50cm higher than the silage pit mouth.

[0037] (5) Sealing: Cover the silage pit completely with a thick plastic cloth, and the plastic cloth for sealing the mouth of the silage pit is 50 cm more than the edge of...

Abstract

The invention discloses mixed silage containing sweet sorghum and alfalfa, and a preparation method of the mixed silage. The mixed silage comprises the following components by weight percent: 20-40% of sweet sorghum and 60-80% of alfalfa. The preparation method comprises the following steps: harvesting the raw materials, chopping, mixing, filling and compacting, sealing and carrying out silage fermentation. After the mixed silage is used, the problems that the alfalfa is low in content of soluble sugar, high in buffer capacity and difficult to directly silage can be solved, and the problems that the sweet sorghum is higher in coarse fiber content and lower in protein content when being separately silaged can be solved. The prepared novel mixed silage has the characteristics of being high in protein content, low in fiber content and excellent in quality.

Description

technical field [0001] The invention belongs to the technical field of animal feed, in particular to a mixed silage of sweet sorghum and alfalfa and a preparation method thereof. Background technique [0002] Alfalfa (Alfalfa / Lucerne) is a perennial leguminous plant, rich in protein, good palatability, and has the reputation of "the king of grass". Currently, alfalfa is mainly used to make grass products such as hay bales or hay bales. Alfalfa loses about 30% of its nutrients due to respiration, rain, high temperature sunlight, and hay collection, baling, and transportation during hay preparation. In addition, processing grass products such as alfalfa blocks or grass pellets requires machinery and equipment, which is expensive. Silage alfalfa has less nutritional loss, green and juicy, good palatability, high nutritional value and digestibility, therefore, alfalfa silage is one of the best ways to preserve its nutrients. However, affected by many factors, conventional alf...
