Problems solved by technology

[0004] However, the research on silver pomfret compound feed is still very weak, so that the growth rate of silver pomfret under artificial breeding conditions is much lower than that of wild silver pomfret, which is also one of the important factors restricting its large-scale breeding promotion
At present, the compound feed used in silver pomfret breeding has not been fully integrated with the feeding characteristics of wild silver pomfret for research and development design, which leads to low feed utilization rate of farmed silver pomfret

Embodiment 1

[0026] From August 2015 to October 2015, the technology of the present invention was used in the scientific research base of the East China Sea Fisheries Research Institute of the Chinese Academy of Fishery Sciences to carry out feeding experiments:

[0027] A special feed additive for silver pomfret, consisting of the following components in parts by weight: 18 parts of fresh jellyfish, 4 parts of chilled scleropoda, 4 parts of diatom (chaetoceros and lunster algae) concentrated solution, butyric acid 0.8 parts of Clostridium powder, 1.5 parts of soybean lecithin, 0.8 parts of vitamin C polyphosphate, and 6 parts of hypodermic powder.

[0028] Silver pomfret feed: by fish meal (ratio 61wt%), soybean meal (16wt%), flour (10wt%), fish oil (5wt%), soybean oil (5wt%), multivitamin (2wt%) and compound mineral (1wt%) ) composition, its protein content 49wt%, fat content is 16wt%.

Abstract

The invention relates to the field of aquaculture, and particularly relates to a special feed additive for silvery pomfret. The special feed additive for the silvery pomfret is prepared from the following components in parts by weight: 15-20 parts of fresh jellyfish, 3-5 parts of iced fresh copepoda, 3-5 parts of diatom concentrated liquor, 0.5-1 part of clostridium butyricum powder, 1-2 parts of soybean lecithin, 0.5-1 part of vitamin C polyphosphate and 5-8 parts of wheat middling. The invention also provides a preparation method and application of the feed additive. The feed additive provided by the invention can effectively promote the digestion and absorption ability of the silvery pomfret and the utilization rate of the feed, greatly improves a growth rate of the silvery pomfret, and meanwhile, obviously promotes the immunity of an organism.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a special feed additive for silver pomfret. Background technique [0002] Silver pomfret is a very promising future breeding target in China. The Donghai Fisheries Research Institute of the Chinese Academy of Fishery Sciences has achieved a series of research results after more than ten years: established the key technology of artificial breeding of silver pomfret; He developed the artificial breeding technology of silver pomfret and established different breeding models; carried out a series of basic biological research on silver pomfret, which laid a theoretical foundation for artificial breeding and breeding; systematically carried out the analysis of the germplasm resources of pomfret in my country, and for its resources Protection and breed selection provide data support. In the past two years, a pilot test base for silver pomfret breeding has been successfully establishe...
