Problems solved by technology

In many parts of our country, due to the influence of seasons and climate, it is necessary to use alfalfa silage to reduce the loss of nutrients such as leaf protein and maintain its green characteristics. However, alfalfa has low water-soluble carbohydrates and high buffer capacity, and cannot produce enough fermented acid during silage. , prone to fermentation of harmful bacteria such as Clostridium, reducing the quality of silage, and even mildew and deterioration in severe cases, making it unusable

Embodiment 1

[0030] Materials and methods:

[0031] Mow the alfalfa with a forage harvester, dry it in the open air until the water content is about 65%, chop the alfalfa to 2-5cm with a guillotine, prepare silage bags with a size of 26cm×35cm, and make silage with 0.5kg of alfalfa per bag , doses I, II, and III were 1.5ml, 3ml, and 6ml of refined wood vinegar (3L, 6L, and 12L / t), and the control group added an equal amount of distilled water to replace the silage additive. Each treatment was repeated 3 times, and the added The mixture was mixed with alfalfa and placed in a silage bag, which was vacuum-sealed. After 45 days, the nutrition and silage fermentation quality indicators of the alfalfa silage samples were measured by a near-infrared analyzer. The data results are expressed as "mean ± standard deviation", and the nutritional and fermentation indicators are comprehensively evaluated by the membership function method.

[0032] result:

[0033] It can be seen from Table 2 that the ...

Embodiment 2

[0041] Materials and methods:

[0042] Select different varieties of alfalfa under different management methods in different plots, and record them as alfalfa group I and alfalfa group II. The alfalfa is mowed by a forage harvester. Crush to 2-5cm, prepare silage bags of 26cm×35cm size, make silage according to 0.5kg alfalfa per bag, use 3ml refined wood vinegar (6L / t) for the treatment group, add 3mL distilled water to replace the silage additive for the control group, each Three replicates were processed, the additives were mixed with alfalfa and placed in silage bags, vacuum-sealed, and after 45 days, the nutrition and silage fermentation quality indicators of alfalfa silage samples were measured by near-infrared analyzer. The data results are expressed as "mean ± standard deviation", and the nutritional and fermentation indicators are comprehensively evaluated by the membership function method.

[0043] result:

[0044] It can be seen from the nutritional and fermentatio...

Embodiment 3

[0052] Materials and methods:

[0053] Refined wood vinegar is commercially available purified bamboo vinegar.

[0054] How to use: The special machinery for alfalfa silage cuts alfalfa at the early flowering stage, chops the alfalfa to 5cm, sprays the refined wood vinegar evenly on the surface of the alfalfa at a dose of 9L / t, puts in the cellar, compacts and seals it, and opens the cellar after 60 days use.

[0055] Sample collection: After the cellar is opened, the silage sample is collected with the 9-point sampling method. The upper material layer is removed by 50 cm, and a quadrilateral is made at a distance of 30 cm from the two walls of the silo cellar and the bottom of the silo cellar, and then the midpoints of each side are connected, and each line intersects Sampling was carried out with each point as the center, and 20cm*20cm*20cm feed blocks were cut with a sterilized sharp knife, and packed in ziplock bags.

[0056] The nutrition and silage fermentation quality...

Abstract

The invention discloses an ensiling additive for alfalfa ensiling and an application thereof. Fine wood vinegar is uniformly sprayed onto an alfalfa surface for alfalfa ensiling or wrapping ensiling. The dosage of the fine wood vinegar is 3-12L / t. According to the method provided by the invention, the proportion of soluble protein and rumen degrading protein in crude alfalfa ensiling protein and the proportion of lactic acid in total VFA are increased; pH value, lignin content in dry matter, the proportion of ammoniacal nitrogen, acidic washing insoluble protein and neutral washing insoluble protein in the crude protein and the proportion of acetic acid in total VFA are reduced, so that the nutrient loss of the alfalfa ensiling is reduced and the fermenting quality and palatability of the alfalfa ensiling are improved; the ensiling additive for alfalfa ensiling is characterized by being green, pollution-free, high in efficiency and low in cost; the ensiling material loss is reduced; the ensiling fermenting quality is improved; the effect of effectively storing the ensiling material is lastly achieved.

Description

technical field [0001] The invention belongs to the technical field of silage processing in livestock feed. Specifically disclosed is a silage additive for alfalfa silage and an application thereof. Background technique [0002] Alfalfa is a perennial herbaceous plant of the leguminous family, rich in protein and digestible fiber, with high nutritional value and good palatability, it is a high-quality protein feed. In recent years, with the development of animal husbandry and the adjustment of the agricultural industry structure, especially the implementation and development of the national "high-yield and high-quality alfalfa demonstration construction project", the alfalfa planting area in my country has rapidly expanded. In many parts of our country, due to the influence of seasons and climate, it is necessary to use alfalfa silage to reduce the loss of nutrients such as leaf protein and maintain its green characteristics. However, alfalfa has low water-soluble carbohydr...
