Selenium-rich oyster feed and preparation method thereof

Abstract

The invention relates to the technical field of oyster cultivation, in particular to selenium-rich oyster feed and a preparation method thereof.The selenium-rich oyster feed is prepared from, by mass, 18-32 parts of selenium-rich corn flour, 8-14 parts of sweet potato powder, 9-15 parts of selenium-rich spirulina, 7-9 parts of coscinodiscus, 7-9 parts of thalassemia, 3-5 parts of shrimp shell meal, 3-5 parts of fish bone meal and 2-6 parts of silkworm chrysalis meal. 10-18 parts of sesame oil residues, 5-8 parts of a traditional Chinese medicine mixed solution, 2-3 parts of a compound vitamin additive, 1-1.5 parts of selenium-enriched yeast and 0.2-0.4 part of cellulase. According to the invention, the selected coscinodiscus and thalasiosira in the raw materials are natural biological baits for oysters in a natural sea area environment, and the added selenium-enriched spirulina enables the content of selenium in the feed to be rich, so that the feed also has relatively strong oxidation resistance and immune function, the immunity of the oysters is improved, and the feed is suitable for being eaten by the oysters. The feed can effectively enhance the physique of the oysters, reduces the prevalence rate of the oysters, also reduces the breeding labor amount and the breeding cost, and is safer to eat aquatic products.

Description

technical field [0001] The invention relates to the technical field of oyster cultivation, in particular to a selenium-enriched oyster feed and a preparation method thereof. Background technique [0002] Oysters are the most common shellfish in my country's coastal areas, commonly known as oysters, oyster yellows, and sea oysters. Their soft parts contain 45% to 57% of protein, 7% to 11% of fat, and 19% to 38% of glycogen. It also contains a variety of vitamins, ash, etc., has high nutritional value, and is known as "sea milk". In addition to its delicious taste, oyster meat also has certain medicinal value. Oyster has low cholesterol content and high zinc content, which helps to improve male sexual function. [0003] Industrialized farming and some retail farming. In the breeding process of aquatic animals, feed is an indispensable staple food for aquatic animals.

Problems solved by technology

However, most of the existing feeds have added a large amount of chemical ingredients, such as antibiotics, hormones, etc. The abuse of these substances makes oysters produce strong drug resistance, and the physique of aquatic animals is also getting worse and worse. The disease ability is poor, which seriously affects the growth of oysters, and the disease rate is gradually increasing, and the mortality rate is also increasing. Farmers need to frequently replace therapeutic drugs or increase the dosage of drugs to treat aquatic animal diseases. Therefore, the cost of farming for farmers Substantial increase, breeding difficulty and farming labor are also increasing
