Description

Technical Field

[0001] The invention relates to the technical field of feed, in particular to green feed fermentation powder and a preparation method thereof. Background Art

[0002] In animal husbandry and breeding, the quality of feed is directly related to the growth rate, health status of animals and the quality of the final product. Traditional feed fermentation methods usually involve the temporary addition of fermentation microorganisms, which are mixed with ingredients in the feed formula such as corn stalks, wheat straw, rice straw, weeds, etc. after adding water and then put into the fermentation tank for fermentation. Although the nutritional value and digestibility of the feed have been improved to a certain extent, there are still many limitations:

[0003] Long fermentation time: Traditional fermentation methods require sufficient time for fermentation microorganisms to reproduce, so the fermentation process is often long, sometimes taking 1 to 3 months. This not only prolongs the feed preparation cycle, but also increases the difficulty of storage and management.

[0004] Complex process: The traditional fermentation process involves multiple steps, including the addition of microorganisms, mixing of ingredients, control of fermentation conditions, etc. The operation is complicated, has high technical requirements, and the fermentation effect is easily affected by improper operation.

[0005] High cost: Due to the long fermentation time and complex process, traditional fermentation methods require a large amount of fermentation microorganisms and manpower and material resources, resulting in high costs. In addition, long fermentation may also increase the risk of feed deterioration, further increasing costs.

[0006] Nutritional imbalance: Traditional fermentation methods often make it difficult to accurately control nutrient conversion during the fermentation process, resulting in nutritional imbalance in the fermented feed, which may lack certain essential amino acids, trace elements and other nutrients.

[0007] Antibiotic dependence: In order to ensure the health of animals, antibiotics are often added to traditional feed. However, the abuse of antibiotics may not only lead to drug resistance in bacteria in animals, but may also be transmitted to humans through the food chain, posing a potential threat to human health.

[0008] Therefore, it is of great significance to develop a green feed fermentation powder that can ferment quickly, has balanced nutrition, low cost and stable effect. The present invention aims to develop a green feed fermentation powder by optimizing the raw material ratio and fermentation process to meet the needs of animal husbandry for efficient, safe and environmentally friendly feed.
