Feed for juvenile yellow croakers and preparation method of feed

Abstract

The invention belongs to the field of feeds, and particularly relates to a feed for juvenile yellow croakers and a preparation method of the feed. The feed is prepared from the following raw materials in parts by weight: 20-40 parts of shrimp powder, 20-40 parts of moringa tree leaf powder, 18-25 parts of pea powder, 12-18 parts of tapioca, 10-20 parts of kelp powder, 8-12 parts of lettuces, 2-4 parts of zeolite, 20-30 parts of palm oil, 15-25 parts of linseed oil, 6-10 parts of inositol, 3-8 parts of a vitamin premix, 2-6 parts of composite amino acids, 4-8 parts of catabolic enzymes, 20-30 parts of traditional Chinese medicine powder and 2-5 parts of an antioxidant. According to the feed disclosed by the invention, in accordance with the development condition of the digestive system and the immune system of the juvenile yellow croakers, the raw materials are screened, the composite nutrition feed containing the substances of protein, fat, amino acids, vitamins and the like is further prepared, and the protein, the fat and the amino acids are in a reasonable proportion and collocation, so that the sufficient absorption of nutrient substances by the juvenile yellow croakers is further promoted, and the feed digestibility is increased.

Description

technical field [0001] The invention belongs to the field of feed, in particular to a feed for juvenile yellow croaker and a preparation method thereof. Background technique [0002] Yellow croaker, also known as yellow croaker, is a collective name for yellow croaker, a genus of yellow croaker in the genus Yellow croaker. It is one of the important economic fish in China. From the south to the east of the Leizhou Peninsula in the South China Sea, this fish is a warm-temperature group swimming fish, and often inhabits the middle and lower layers of the offshore waters within a water depth of 60 meters. The large yellow croaker has two reproductive seasons: spring and autumn. Batch from the wintering area in the open sea to the offshore for reproductive migration. As a valuable economic fish, large yellow croaker has long been favored by consumers. Yellow croaker is rich in protein, minerals and vitamins, which has a good tonic effect on the human body and is beneficial to we...

Problems solved by technology

[0003] In view of the high medicinal value and edible value of yellow croaker, the market demand for yellow croaker has been increasing day by day in recent years, and juvenile fish, as the new force and backup guarantee of fish farming, have important leading significance. The development of juvenile fish directly affects the later stage. The output and quality of adult fish are issues, while the development of juvenile fish is inseparable from the nutrition and quality of the feed. In the juvenile fish stage, due to the development of the gastrointestinal digestive system and immune system Incomplete, if the feed is not matched properly, it will easily lead to disease and diarrhea of ​​juvenile yellow croaker fish, reducing the survival rate of juvenile fish, so it will have a huge impact on the output and quality of adult fish in the later stage, and it will be difficult to satisfy At present, there is a huge demand for yellow croaker in the market. It can be seen that in the juvenile stage of yellow croaker, according to the development of the gastrointestinal digestive system and immune system of the juvenile fish, as well as the demand for nutrients, etc., the juvenile fish suitable for growth and development Feed is the focus of current research. At the same time, it can also solve the problems of diarrhea, anorexia, and disease in juvenile yellow croaker fish due to unreasonable feed nutrition, which makes their survival rate low and affects the output of adult fish. The status quo of quality and other issues provides a new idea for the feed research of yellow croaker and even fish farming industry in the juvenile stage
