Straw fermented feed and preparation method thereof

Abstract

The invention belongs to the technical field of feed processing, and discloses a straw fermented feed and a preparation method thereof. The straw fermented feed comprises the following raw materials:green straw, traditional Chinese medicines, white carbon black, fumaric acid, montmorillonite powder, compound microorganisms and cellulase. The preparation method comprises the following steps: (1) harvesting the green straws, removing impurities, cutting the green straws into small sections with a length of 3-4 cm by using a chopping machine, and regulating moisture so as to obtain a silage rawmaterial; (2) respectively diluting the compound microorganisms and the cellulase with water, uniformly mixing the diluted compound microorganisms and cellulase with the silage raw material, loading an obtained mixture into a clean bag in a layered manner, treading and compacting the mixture once when the bag is filled with the mixture with a thickness of 25-35 cm, exhausting air, and tightening abag opening by using a rope; and (3) putting a material obtained in the step (2) into a fermentation tank for anaerobic fermentation, taking a fermented material out of the fermentation tank, addingthe white carbon black, the fumaric acid and the montmorillonite powder in proportion, and performing uniform mixing so as to obtain the straw feed. The straw feed disclosed by the invention takes thegreen straws and the Chinese herbal medicines as main raw materials, has the effects of strengthening the spleen and stomach, improving the appetite of livestock and enhancing the resistance of the livestock, and increases the weight of the livestock.

Description

technical field [0001] The invention belongs to the technical field of feed processing, and relates to straw fermented feed and a preparation method thereof. Background technique [0002] As my country's grain production increases year by year, the output of crop straw is also increasing year by year. The annual output of my country's crop straw has exceeded 1 billion tons, becoming one of the most abundant substances in the world. The comprehensive utilization rate of straw in the country is about 80%. It is mainly used in straw returning to fields, livestock and poultry feed, biomass energy and light industrial raw materials, etc., but some straws are still directly incinerated or discarded. Straw feed utilization is an economical, environmentally friendly, and ecological utilization method. It processes orange stalks into high-nutrition feed for animal husbandry and improves the utilization rate of crop orange stalks. [0003] Straw is a low-quality forage grass, which ca...

Problems solved by technology

[0004] At present, microbial fermented feed has been used in animal husbandry in my country to a certain extent, but there are still problems of low nutritional value and low utilization rate, and the traditional fermentation method has problems of incomplete fermentation, less metabolites, high energy consumption, and low number of effective viable bacteria , The effect is poor in breeding applications, the shelf life is short, and it is easy to deteriorate
