Description

Device for producing fish feed by using chicken manure and preparation method thereof

Technical Field

The invention belongs to the technical field of modern agricultural environment protection, relates to a preparation method for producing fish feed, and particularly relates to a device for producing fish feed by using chicken manure and a preparation method thereof.

Background

The chicken digestive tract is short, the feed enters the digestive tract of the chicken and is quickly excreted, the nutrients in the eaten feed can be generally absorbed by about 30 percent and most of the nutrients are discharged through the rectum, so a large amount of nutrient substances remain in the chicken manure, and in order to increase the utilization value of the chicken manure, the chicken manure is made into fish feed for feeding the fish, thereby effectively improving the fish-farming benefit.

Meanwhile, the chicken manure is comprehensively utilized, so that the sanitary environment of a chicken farm can be greatly improved, mosquitoes, flies and odor are eliminated, the spread of diseases is reduced, the resource can be fully utilized to be used as feed, fertilizer and the like, the chicken manure is changed into valuable, and better social benefit, ecological benefit and economic benefit are generated.

The nutrient substances contained in the chicken manure are different with the difference of the feed ingested by the chicken, various amino acids in the chicken manure are balanced, and each kilogram of dried chicken manure contains 5.4 g of lysine, 1.8 g of cystine and 5.3 g of threonine, which are all higher than the contents of corn, sorghum, bean cake, cottonseed and the like. The faeces of 1000 chickens, 1 year old, correspond to a crude protein content of 25 tonnes in peas. In addition, there are B vitamins, especially vitamin B12, and various trace elements. The crude protein in the dry matter of the chicken manure accounts for 31 to 33 percent, more than half of the crude protein is non-protein nitrogen such as uric acid, urea, creatine, ammonia and the like, and crude fiber contained in the chicken manure and a large amount of crude fiber in bedding grass, so the chicken manure is good feed for breeding fish.

However, the raw chicken manure contains parasitic ova and some toxic substances and germs, and the fish is directly fed by the raw chicken manure, which causes serious water pollution. Therefore, the raw chicken manure can not be directly fed, and the raw chicken manure needs to be subjected to certain sterilization treatment, so that the raw chicken manure can be changed into the nontoxic and nutrient-rich fish feed.

However, the existing processing device is large in size and difficult to operate, the process for preparing the fish feed is complex and high in cost, fresh chicken manure cannot be efficiently and quickly dried, sterilized and ground, and the fish feed cannot be quickly and fully mixed with other ingredients.
