Problems solved by technology

[0008] The above-mentioned invention has the following defects: there are few acid-producing microorganisms in the additive, and after adding alfalfa, the fermentation strength is not enough in a short period of time, and the acid-producing ability is not strong; the inhibitory effect on miscellaneous bacteria is low, which easily causes the loss of nutrients; Low or no decomposition ability, affecting the utilization of crude fiber

Embodiment 1

[0036] A method for baling and wrapping alfalfa silage, comprising the following processing steps:

[0037] ⑴Preparation of special silage additive for alfalfa

[0038] ①Preparation of additive a: Mix 3kg of Acanthopanax, 3kg of Schisandra, and 6kg of Astragalus into a Chinese medicine composition, add 30kg of water, soak the liquid surface with Chinese medicine, place it at 4°C for 24h, extract at 70°C for 30min, and filter After that, add 30kg of water, extract at 80°C for 40min, filter again, mix the medicinal liquid after the two filtrations, and concentrate it to 12L at 75°C to obtain 1g / ml Chinese medicinal liquid, add selenium content to it. 27.27g of 44% sodium selenite to make the concentration of selenium reach 1mg / ml, stir evenly, seal, and store at 4°C;

[0039] ②Preparation of additive b: Mix 6g of Streptococcus thermophilic lactis, 4g of Pediococcus lactis, 3g of Pediococcus pentosaceae, and 3g of Bacillus subtilis into a mixed bacterial powder; mix 24g of cellu...

Embodiment 2

[0049] A method for baling and wrapping alfalfa silage, comprising the following processing steps:

[0050] ⑴Preparation of special silage additive for alfalfa

[0051] ①Preparation of additive a: Mix 3.5kg of Acanthopanax, 3.5kg of Schisandra, and 7kg of Astragalus into a traditional Chinese medicine composition, add 35kg of water, soak the liquid surface with Chinese medicine, place it at 4°C for 24h, then extract at 70°C for 30min , after filtering, add 35kg of water, extract at 80°C for 40min, then filter again, mix the liquid medicine after two times of filtration, and concentrate to 14L at 75°C to obtain 1g / ml Chinese medicine liquid, add selenium to it 31.815g of sodium selenite with a content of 44%, so that the concentration of selenium reaches 1mg / ml, stir evenly, seal, and store under the condition of 4°C;

[0052] ②Preparation of additive b: Mix 8 g of Streptococcus thermophilic lactis, 3 g of Pediococcus lactis, 1 g of Pediococcus pentosaceae, and 4 g of Bacillus...

experiment example

[0062] The packaged silage alfalfa feed processed in Example 2 was compared with the common dry alfalfa feed, and the crude protein content, moisture content, crude fiber content, crude ash content and mildew degree of each storage period were measured respectively.

[0063] Experimental measurement data records, as shown in the following table:

[0064]

[0065] Through the comparative analysis of the data, the results show that the components of alfalfa can basically maintain the same quality after being baled and wrapped for silage, and the influence of external factors is small, while the nutritional components of alfalfa hay change greatly, and its nutritional components lose greatly.

Abstract

The invention discloses an alfalfa bundling and wrapping ensiling method, and belongs to the field of processing of silage. The method comprises the steps of rolling and cutting alfalfa with two sub-steps, spraying different additives with sub-steps and then bundling and wrapping. A good reproduction environment is created for the anaerobic fermentation of probiotics in an ensiling process, and the reproduction of other harmful bacteria is suppressed; the additives are high in acid productivity, so that the pH of feeds can be rapidly lowered to well store nutritional ingredients in the feeds, the quality of the feeds can also be improved, the livestock disease resistance enhancement capability of the feeds can be improved, and healthy growth of livestock can be promoted; the method is high in mechanization and automation degree, easy to operate and high in speed and efficiency, the influence of weather is slight, and the feeds are convenient to transport and apply.

Description

technical field [0001] The invention belongs to the field of silage processing, and relates to a method for processing alfalfa silage, in particular to a method for bundling and wrapping alfalfa silage. Background technique [0002] Alfalfa is a perennial forage, known as the "king of forage" because of its high crude protein content. At present, most of the alfalfa fed by domestic large-scale dairy farms and beef cattle and sheep farms is mainly straw bales and supplemented by pellets. After alfalfa is turned into hay, its nutrient content decreases to varying degrees, especially because the crude protein content of alfalfa mainly exists in its leaves. Nutrients drop. Processing green alfalfa directly into silage is a common method to preserve its nutritional content. [0003] Silage is a kind of roughage obtained by chopping green fodder and anaerobic fermentation under airtight conditions. Silage can effectively preserve the nutritional content of high-moisture feed, ...
