preparation example Construction

[0021]The preparation method of seabuckthorn extract is as follows: wash 120-150 parts of seabuckthorn in parts by mass and grind until gelatinized to form a slurry; At -65°C, carbon dioxide is used as a solvent for supercritical extraction, concentrated, placed in ice water solution for ultrasonic extraction for 30-45 minutes, filtered, and the filtrate is collected to obtain the seabuckthorn extract.

[0022] The preparation method of Eucommia ulmoides extract is as follows: wash 120-150 parts of eucommia ulmoides in parts by mass and grind until gelatinized to form a slurry, add pure water 4-5 times the weight of eucommia ulmoides to the slurry, and set the temperature at 100-120Mpa, 55 At -65°C, carbon dioxide is used as a solvent for supercritical extraction, concentrated, placed in ice water solution for ultrasonic extraction for 30-45 minutes, filtered, and the filtrate is collected to obtain the Eucommia extract.

Abstract

The invention relates to a high-fat black porgy feed which is composed of the following substances in percentage by weight: 20-30% of fish meal, 30-40% of soybean protein concentrate, 15-20% of high gluten flour, 6-9% of fish oil, 6-9% of corn oil, 1% of sodium dihydrogen phosphate, 1% of vitamin complex, 1% of composite mineral, 0.02% of phytase, 0.1-0.3% of composite amino acid, 2% of soybean lecithin and 2-3% of fat-lowering factor. When the high-fat black porgy feed is used for cultivation production, the fat-lowering factor is added into the feed to promote the liver fat metabolism and prevent the fatty liver from generation, thereby achieving the goals of reducing the protein consumption by reducing the quantity of protein for energy supply, lowering the cultivation feed cost and relieving the cultivation water body pollution caused by nitrogen excretion on the premise of not influencing the healthy growth of black porgies.

Description

technical field [0001] The invention belongs to the technical field of fish feed, and relates to a high-fat black sea bream feed that promotes fat metabolism in the liver, prevents the occurrence of fatty liver, reduces the cost of aquaculture feed, and reduces the pollution of nitrogen excretion to aquaculture water. Background technique [0002] Black sea bream (Acanthopagrus schlegelii) (common scientific name Sparus macrocephalus), belongs to the class of ray-finned fishes, the order of Perciformes, the family of breams, and the genus of bream. Black sea bream is a rare and valuable economic marine fish cultured in the southeast coast of my country and Japan, South Korea, Taiwan, Southeast Asia and other countries and regions. The adult fish has delicious meat and high nutritional value, and is welcomed by consumers at home and abroad. It is one of the most potential targets for intensive marine fish farming in the future. [0003] Fat is an important nutrient substance...
