The invention belongs to the field of microbial
fermentation, and particularly relates to a microbial
fermentation feed and a preparation method and application thereof. The preparation method of the microbial
fermentation feed includes the following steps that a
plant base material is smashed, then a complex
enzyme preparation is added and mixed for
hydrolysis, and an enzymolysis product is obtained; the enzymolysis product is mixed with
rumen content for anaerobic liquid fermentation, and a fermentation product 1 is obtained; the fermentation product 1 is mixed with a complex microbial solution 1 for anaerobic
solid fermentation, and a fermentation product 2 is obtained; the fermentation product 2 is mixed with a complex microbial solution 2 for aerobic
solid fermentation, and a fermentation product 3 is obtained; the fermentation product 3 is dried, smashed and sieved, and the microbial fermentation feed is obtained. By adopting
solid-liquid combined fermentation and aerobic-anaerobic combined fermentation, the obtained feed contains rich
cellulose nutrients, increases the food
nutrient utilization rate and is high in
protein content and beneficial to animal growth and development. By means of the microbial fermentation feed and the preparation method and application thereof, the breeding cost of the
animal husbandry can be comprehensively reduced, and a large amount of grain for preparing
livestock feed can be saved.
