Alfalfa fresh grass storage additive and preparation method thereof

Abstract

The invention discloses an alfalfa fresh grass storage additive and a preparation method thereof. The additive is prepared from sodium benzoate, sodium propionate and water in a weight ratio of (0.38-0.42) to (0.12-0.08) to 1. The preparation method comprises the following steps: weighing the sodium benzoate, the sodium propionate and the water in a proportion firstly; adding the sodium benzoate and the sodium propionate into the water; uniformly stirring to prepare the alfalfa fresh grass storage additive. Alfalfa silage prepared from the alfalfa fresh grass storage additive has the yellow green color and is delicious in taste, and dairy cow like to eat the alfalfa silage; after the alfalfa silage is stored for half a year, the test analysis shows that the content of ammonia nitrogen and butyric acid is very low, and the nutritive value of the stored alfalfa silage is as the same as that of fresh alfalfa; after the alfalfa is stored for one year, the apparent identification shows that the content of the alfalfa is still in a normal level; alfalfa silage dairy cow feeding tests show that after the dairy cow are fed with the alfalfa silage, the milk production and the feed conversion ratio can be increased; in the test period of the whole three months, tested cow have no bad symptoms and are good in health condition.

Description

technical field [0001] The invention relates to the technical field of alfalfa fresh grass storage additives, in particular to an alfalfa fresh grass storage additive and a preparation method thereof. Background technique [0002] Alfalfa is known as the "King of Forage Grass". It is one of the most widely cultivated and most important leguminous forage grasses in the world, and is the main grass species for artificial grassland construction. 160-180 million mu are planted all over the world, and the direct annual income of alfalfa in the United States reaches 10 billion U.S. dollars, and the annual output value of related industries such as cultivation and processing exceeds 100 billion U.S. dollars. my country has a history of more than 2,000 years of planting alfalfa, and the current area of ​​alfalfa ranks fifth in the world. [0003] The planting mode of alfalfa in my country is mostly scattered planting by farmers for self-production and self-use. With the developmen...

AI Technical Summary

Problems solved by technology

After adding sugar or lactic acid bacteria for storage, the alfalfa can be prevented from going bad, but during the fermentation process, the nutritional content of the alfalfa will be lost. After opening the cellar and taking it out of the cellar, it is easy to produce secondary fermentation and reduce the quality.

However, formic acid and propionic acid are highly corrosive, which can easily cause human injury and mechanical corrosion.

At present, some alfalfa silage additives imported from abroad have the advantages of non-corrosion, direct contact between humans and animals, and good nutritional value. Therefore, they are relatively good alfalfa silage additives alone. However, if the animal eats within one month after spraying the additive , symptoms of poisoning will occur, and a large investment
