Antibacterial fly maggot protein and preparing method thereof

Abstract

The invention discloses an antibacterial fly maggot protein and a preparing method thereof. The preparing method comprises the following steps of mixing a mixed bacterial liquid and a culture base material to obtain a mixed material; putting young project fly maggots into the mixed material, and conducting first-stage fermentation, second-stage fermentation and third-stage fermentation. By means of the technology, the powerful degradation capability of external digestion of the fly maggots can be fully utilized; meanwhile, the coordinated symbiosis effect of the fly maggots and associated bacteria thereof is also enhanced, so that the enzymolysis effect of a double-fermentation device on the material is more considerable. The antibacterial fly maggot protein can be used as a conventional raw protein feed material in porcine complete feeds. The antibacterial fly maggot protein can provide protein nutrients, can effectively control the diarrhea rate of piglets and can also be used for replacing zinc oxide in the porcine feeds.

Description

technical field [0001] The invention relates to the field of breeding feed, and mainly relates to an antibacterial fly maggot protein and a preparation method thereof. Background technique [0002] Since 2015, my country's total feed production has exceeded 200 million tons for four consecutive years. Among them, protein raw materials, as one of the main raw materials in feed, have a huge demand. About 60 million tons of soybeans and fish meal need to be imported every year. In 2020, there is still a shortage of 50 million tons of protein raw materials in my country. Therefore, the development and utilization of new high-quality protein resources has become an imminent new task for the feed industry. [0003] Animal-derived feed (fish meal, plasma protein powder, intestinal membrane protein powder, meat and bone meal) is a feed material made from the animal itself or the waste after slaughtering the animal. In terms of composition, they are all excellent protein resources. ...

Problems solved by technology

[0008] In view of the above-mentioned deficiencies in the prior art, the object of the present invention is to provide a kind of antibacterial fly maggot protein and preparation method thereof, described antibacterial fly maggot protein can be used in pig full-price feed as a kind of conventional protein feed raw material, besides can provide In addition to protein nutrition, it can also effectively control the diarrhea rate of piglets, and can be used to replace zinc oxide in pig feed, aiming to solve the problem that a large amount of zinc enters the soil with manure and pollutes the soil caused by the use of high doses of zinc oxide in existing pig feed The problem
