Method for improving of high-moisture alfalfa ensiling quality by adding feed jujube powder

A high-moisture, alfalfa technology is applied to the preservation method, application, and animal feed of animal feed materials. It can solve the problems of high price, increased silage production cost, and unsatisfactory high-moisture alfalfa silage, and achieve quality improvement, production and production. Use high quality and high efficiency to change the effect of carbohydrate deficiency

Embodiment Construction

[0014] A kind of method of improving high-moisture alfalfa silage quality by adding jujube powder for forage in the embodiment of the present invention is as follows:

[0015] 1. Harvest the alfalfa and chop it to a length of 2-3cm, and weigh it.

[0016] 2. Put the chopped fresh alfalfa into the silo, and flatten it. The flattened thickness is about 8-12cm, generally about 10cm; according to the weight of the alfalfa, weigh 3%-12% for feeding Jujube powder, and evenly sprayed on the flattened alfalfa, the optimal amount of jujube powder for feeding is 6%.

[0017] 3. Use special cellar pressing machinery or suitable alternative machinery for compaction, and the compaction density should be controlled at 500kg / m 3 -650kg / m 3 If the compaction density is too low, there will be too much residual air in the silo, which will affect the quality of fermentation and alfalfa silage; if the compaction density is too high, the juice in the alfalfa will seep out in large quantities, re...

Abstract

The invention relates to a method for improving high-moisture alfalfa ensiling quality. The method comprises the following steps: (1) harvesting alfalfa and chopping to a length of 2-3cm, and weighing; (2) pouring the chopped fresh alfalfa into an ensiling pit, and spreading to a thickness of about 8-12cm; weighing the feed jujube powder accounting for 3-12% of the alfalfa weight according to weighed alfalfa; and uniformly spraying the feed jujube powder on the spread alfalfa; (3) compacting by use of special pit pressing machinery or proper substitute machinery, wherein the compaction density is controlled at 500-650kg / m<3>; and in the same manner, compacting layer by layer and filling until the ensiling pit is full; and (4) covering and sealing the top of the filled ensiling pit with plastic cloth, and compacting. By adopting the method provided by the invention, the high-molecular alfalfa ensiling can be finished economically and effectively while the quality of alfalfa silage is improved, and the effective utilization means of the feed jujube powder is expanded; by organically combining the alfalfa production and the waste utilization of the jujube industry, a win-win effect is realized.

Description

technical field [0001] The invention relates to a method for making high-moisture alfalfa silage, in particular to a method for improving the quality of high-moisture alfalfa silage by adding feed jujube powder. Background technique [0002] In the production of alfalfa silage, the sugar content of raw materials is low and it is difficult to silage, especially the high-moisture alfalfa (moisture content 70%-80%) silage. At present, additives are often used in the world to solve this problem. However, most of the existing additives are imported or packaged products, which are expensive and increase the production cost of silage; at the same time, most of the additives are more suitable for low-moisture alfalfa silage, but not ideal for high-moisture alfalfa silage. Contents of the invention [0003] The purpose of the present invention is to provide a method for improving the quality of high-moisture alfalfa silage by adding jujube powder for forage. The effective utilizat...
