Animal feed and preparation method thereof

Abstract

The invention relates to an animal feed and a preparation method thereof. The preparation method of the animal feed comprises the steps of: using biological leftovers as raw materials; evenly contacting hametz with the biological leftovers; and carrying out 2-5-day fermentation on the biological leftovers at a temperature of 15 DEG C-45 DEG C so as to obtain the animal feed; wherein the mass ratioof the biological leftovers and the hametz is 50 : 1-10 : 1. The preparation method of the animal feed is simply operated and has good effect. The biological leftovers which undergo microorganism flora treatment can be used as feed and are completely fermented, and the prepared feed has good taste and high bioavailability; animals which eat the feed can build up resistance, the stink of the wasteof the animals is obviously reduced; and the feed can be preserved for a long time in the presence of oxygen and at the normal temperature and has low cost for processing and storage.

Description

technical field [0001] The invention relates to a feed and a preparation method thereof, in particular to an animal feed and a preparation method thereof. Background technique [0002] With the development of agriculture, on the one hand, the livestock and poultry breeding industry is growing rapidly and requires a large amount of feed, while the traditional feed formula is mainly based on grain, which not only has the problem of competing with people for grain, but also with the increase in grain prices, feed The price is getting higher and higher, which increases the cost of breeding and reduces the profit of breeding. Some industries such as chicken, cattle, including beef and dairy cattle, and pig farming have reached a state of meager profit or even loss. If things go on like this, the industry will collapse. . On the other hand, a large amount of agricultural waste is discarded in vain, which not only causes waste but also pollutes the environment. The existing techn...

Problems solved by technology

[0004] 1. The microorganisms used to process biological waste are cultured and amplified separately for each single bacterium, and finally mixed together in proportion to make a solid or liquid starter. The various strains have not been domesticated and adapted. And use will cause the vitality of bacteria to decrease, and each strain cannot play the function of processing biological waste as expected

[0005] 2. Since the biological leftovers often contain more miscellaneous bacteria, it is difficult for the traditional microbial starter to become the dominant flora, and it is often polluted by miscellaneous bacteria, especially the bacteria that cause spoilage, which will cause the feed to deteriorate. Therefore, it must be Short-term isolation from the air can be stored for a long time

In this way, on the one hand, the fermentation of biological waste is not complete, and the bioavailability is not high; on the other hand, the cost of processing and storage will increase

[0006] 3. The composition of the medium for cultivating fermentation microorganisms is complex, different bacteria need to use different medium, and the cost is high

[0007] 4. The fermented feed cannot be stored for a long time, especially in the environment of natural stacking, high humidity and high temperature (30-40°C)
