Selenium-enriched fish feed and preparation method thereof

Abstract

The selenium-enriched fish feed is composed of the following raw materials: soybean meal, rice bran meal, fish meal, meat and bone meal, wheat flour, corn flour, aburs cantoniensis, phyllostachys glauca leaves, tanacetum vulgare, citri reticulatae pericarpium, garlic, allium tuberosum seeds, cortex eucommiae, edible salt, compound vitamins, and yeast selenium. The soybean meal is crushed by selenium-enriched peas, the rice bran meal is selenium enriched unhusked rice bran meal and the corn flour is ground by selenium-enriched corn. The present invention also discloses a preparation method of the fish feed, which includes three steps of crushing, mixing and fermenting or four steps of crushing, mixing, liquid medicine preparing, and liquid medicine soaking. The traditional Chinese medicines and yeast selenium are added into the fish feed, which can enable the prepared fish feed to be richer in nutrition. The selenium-enriched fish feed is conducive to digestion and absorption, plays a certain health-care efficacy, improves the survival rate, reduces the morbidity, accelerates the growth speed of fish, and at the same time enable the fish flesh to be more delicious, more nutritious, and healthier for consumption.

Description

technical field [0001] The invention relates to an aquaculture feed and a preparation method thereof, in particular to a selenium-enriched fish feed and a preparation method thereof. Background technique [0002] Selenium is an indispensable trace element in the human body. Both selenium and vitamin E are anti-peroxidation substances (peroxides are harmful to the human body), and it has also been proved that it has a therapeutic effect on malnourished children caused by lack of protein Carcinogens are resistant. The main manifestations of selenium deficiency in the human body are hair loss and nail loss. Some patients have skin symptoms, and a small number of patients may have neurological symptoms and tooth damage. People with mild or moderate selenium deficiency have no obvious signs or symptoms. Possible diseases caused by selenium deficiency in human body: energy deficiency malnutrition, hemolytic anemia, Keshan disease, Kashin-Beck disease, hypertension, ischemic hear...

Problems solved by technology

Therefore, the number of meat and fish farming in our country is constantly increasing, and large-scale intensive farming of fish meat has been realized. In the process of fish farming, the most important part is feeding management. The selection of fish feed with reasonable preparation and scientific nutrition is the key to realizing The basic premise of maximizing breeding benefits. The existing fish feed lacks various nutrients due to unreasonable formula. Generally, it is fed with a single feed such as corn, grass powder, bean cake, and rice bran, which cannot satisfy the growth and development of fish at all. The demand for nutrition hinders the normal growth and development of fish. The fish grow slowly, the breeding cycle is prolonged, and they are prone to various infectious diseases, which affect the breeding rate and cause loss of benefits. At the same time, the nutritional value of fish is also greatly reduced, and the quality deteriorates.
