Problems solved by technology

The higher amount of fishmeal in the turbot compound feed will inevitably increase the price of the compound feed, thereby increasing the artificial breeding cost of turbot
At the same time, the high fish meal in the feed leads to the phosphorus content in the feed exceeding the nutritional requirements of animals. In addition, soybean meal and other vegetable proteins also contain more phytate phosphorus that cannot be used by animals. These phosphorus that cannot be used by animals are discharged into the water body together, resulting in a environmental pollution

Abstract

The invention provides a low-fish-meal compound feed for turbots. The compound feed is prepared from 12.5-24.5% of Peru steam fish meal, 35-50% of soy protein concentrate, 2.5-4% of enzymolysis fish meal, 1.0-2.0% of mussel meat, 1.0-2.0% of scallop brims, 12-25% of high gluten flour, 0.5-1.0% of soya bean lecithin, 4.5-10% of fish oil, 4.5-10% of soya-bean oil, 0.7-2.1% of taurine, 0.2-0.6% of L-carnitine, 0.1-0.2% of a non-starch polysaccharide enzyme, 0.05-0.15% of phytase, 0.05-0.15% of glucuronolactone, 2.5-3.3% of a compound amino acid mixture, 0.5-1.0% of monocalcium phosphate, 0.1-0.2% of multivitamins for sea fishes and 0.4-0.8% of compound minerals for sea fishes. Compared to a common compound feed for turbots, the feed cost can be more effectively lowered, so that the economical cost of turbot cultivation is lowered. Moreover, the pollution on the water body caused by nitrogen and phosphorus discharge is remarkably reduced.

Description

technical field [0001] The invention belongs to the technical field of animal feed preparation, and in particular relates to a low-fish meal compound feed for turbot. Background technique [0002] Turbot (Scophthalmus maximus L.) belongs to the order of Flatfish, the family Bothidae, and the genus Scophthalmus. It is commonly known as "turkey fish" in China. Turbot is native to the east coast of the Atlantic Ocean, and is mainly produced in the waters near the North Sea, Baltic Sea, Iceland and Scandinavia. Since it was introduced into my country in 1992, it has rapidly developed into a dominant cultured fish species in northern my country due to its advantages such as high economic value, rapid growth, low oxygen consumption, adaptability to low water temperature life, easy acceptance of bait, and suitable for intensive farming. , has become a pillar industry of mariculture in my country, and has achieved good economic and social benefits. According to statistics, at prese...
