Problems solved by technology

The disadvantage is that the liquid of fresh and live unicellular algae needs to be transported and stored at low temperature, and the shelf life is about 7 days, which is not conducive to popularization and application; and the adult oysters have a large feed intake. For the oyster purification plant, the oysters entering the purification tank are about Tens of thousands of catties, the fresh and live unicellular algae liquid that needs to be fed every day is huge, and the fresh and live unicellular algae liquid production enterprises cannot continue to supply
The disadvantage is that the suspension is poor and the waste is serious
However, because fish oil cannot be mixed evenly with other raw materials in the feed, and it will cause agglomeration of the feed, it is impossible to add an appropriate amount of fish oil to the oyster feed

Abstract

The invention relates to the technical field of feeds, in particular to an oyster compound feed rich in fish oil and a preparation method of the oyster compound feed, and solves the problems that the fattening period of oysters is prolonged and the oysters are thin due to natural reasons. The invention provides a fish oil-rich oyster compound feed, which is characterized by being prepared from the following raw material components in parts by weight: 2 to 6 parts of fish oil, 5 to 10 parts of isochrysis galbana, 10 to 20 parts of schizochytrium limacinum, 10 to 20 parts of spirulina platensis, 15 to 25 parts of dunaliella salina, 8 to 12 parts of clostridium ethanol protein, 0.5 to 1 part of compound vitamin additive, 0.5 to 1 part of lipase, 0.5 to 1 part of sucrose fatty acid ester, 5 to 8 parts of sodium caseinate and 20 to 30 parts of corn starch. The invention also provides a preparation method thereof. The feed is used for feeding and fattening oysters.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to an oyster compound feed rich in fish oil and a preparation method thereof. Background technique [0002] Oysters are common shellfish along the coast of my country. They are called oysters in Fujian and Guangdong, oysters in Zhejiang and Jiangsu, and sea oysters or oysters in Liaoning and Shandong. [0003] Oyster is a kind of shellfish with great economic value. It is rich in nutrition and delicious in meat. The dry matter of the soft body contains 45-57% of protein, 7-11% of fat, 19-38% of glycogen, and its iodine content is higher than that of milk. Or egg yolk is 200 times higher and contains a lot of vitamins. It is a high-protein and low-fat seafood, also known as "sea milk". [0004] In recent years, with the rapid growth of oyster culture, it has exceeded the carrying capacity of the culture sea area, causing the amount of phytoplankton in the culture sea area to be insuffi...
