Problems solved by technology

[0004] The technical problem to be solved by the present invention: aiming at the problem that the protein content of the existing tilapia feed is too high, resulting in a low feed protein conversion rate and water pollution, the present invention first mixes banana peels, pears and other substances Squeeze the juice, mix it with cornstarch, soybean meal and other substances to obtain the mixture, and spread the mixture on a glass plate. After placing the earthworms for breeding, collect the earthworms, dry and crush the residue on the glass plate to obtain the tilapia feed base , then dry and pulverize the collected earthworms and chicken livers, mix and cook them with Scutellaria chinensis, seaweed and other substances, filter, mix the filtrate with the tilapia feed base material and let it stand to obtain tilapia feed

Abstract

The invention relates to a preparation method of tilapia mossambica fodder and belongs to the technical field of fodder preparation. According to the invention, the preparation method comprises the following steps: firstly mixing materials such as banana skin and pear and juicing, and mixing with corn starch, bean pulp and the like to obtain a mixture; then paving the mixture on a glass plate, and after placing earthworm for breeding, collecting the earthworm, and drying and smashing residues on the glass plate to obtain the base stock of the tilapia mossambica fodder; and then, after drying and smashing the collected earthworm and chicken liver, mixing and cooking with radix scutellariae, seaweed and the like, filtering, and mixing a filtrate with the base stock of the tilapia mossambica fodder for standing, thus obtaining the tilapia mossambica fodder. In the tilapia mossambica fodder prepared according to the preparation method disclosed by the invention, the protein content is 27-29%, and the protein conversion rate reaches more than or equal to 3.25%, thus being favorable for the tilapia mossambica to digest and promoting the growth of the tilapia mossambica; the problem of overhigh content of ammonia nitrogen in aquatic water cannot be caused, pollution to the water cannot be caused, and the environment is protected.

Description

technical field [0001] The invention relates to a preparation method of tilapia feed, belonging to the technical field of feed preparation. Background technique [0002] Tilapias belong to the order Perciformes, the family Carrionidae, and the genus Tilapia. Originated in Africa, it is a small and medium-sized fish. Now it is a freshwater farmed fish cultivated by key scientific research in the world's aquaculture industry. It is known as one of the main sources of animal protein in the future. It has the advantages of wide appetite, fast growth, high yield, low oxygen resistance, less disease, strong reproductive ability, etc., and the meat is thick, tender, delicious, and has no intermuscular thorns. It is very popular in the market. As the world's largest tilapia breeding base, China ranks among the best in freshwater aquaculture in Guangdong Province. [0003] Tilapia's demand for protein is about 25% to 40%, and various plant raw materials can be effectively used. Ti...
