Abstract

The invention relates to an anti-stress feed additive for cobias, which comprises following ingredients by weight percentages: 0 to 20 percent of vitamin C-2-phosphate, 10 to 20 percent of beta-dextran, 10 to 20 percent of vitamin E, 10 to 15 percent of potassium diformate, 8 to 12 percent of vitamin B1, 8 to 12 percent of vitamin B2, 8 to 12 percent of vitamin B6 and 8 to 12 percent of pretreatment-stage bitter salt containing 15 percent of magnesium. The invention has the advantages that the ingestion rate of the cobias is improved and the growth of the cobias is stimulated; the live rate of the cobias in a complete culture period and the unit yield are improved, and the economic benefits of cobias culture are increased; the meat quality of the cobias is improved, the product quality is improved, and foreign currency by exporting the cobias is increased; and raw materials for the anti-stress feed additive have stable resources, low cost and simple production technology.

Description

A kind of cobio anti-stress feed addictive

Technical field

The present invention relates to a kind of marine fish feed additive, particularly relate to a kind of cobio anti-stress feed addictive.

Technical background

What is called stress (stress) be meant a kind of nonspecific reaction that aquatic livestock is showed the poor environment factor.These factors comprise: water temperature sudden change (as the influence of cold current, heat), water quality mutation (as the influence of typhoon, heavy rain etc.), breeding density is too high, malnutritive and other outside stimulus etc.

Smooth, the delicious flavour of cobio (Rachycentron canadum) fine and tender taste; This fish is made raw fish, is considered to well received Atlantic salmon, the strong competitor of yellowfin tuna raw fish.It is fast to add the cobio growth, has therefore become a kind of important economic fish that China's southern area offshore and deep water mesh cage are cultured.Because breeding density is too high, add that maritime environment pollution, sea environment are complicated and changeable, therefore, usually be in stress situation in the cobio breeding process, have a strong impact on cobio ingest, grow and healthy, also can cause death under the serious situation.But up to the present, research and the application about the cobio anti-stress feed addictive yet there are no report.

Summary of the invention

The purpose of this invention is to provide a kind of cobio anti-stress feed addictive, it can remedy the above-mentioned deficiency of prior art.

Component of the present invention and percetage by weight scope are respectively: vitamin C-2-phosphate, 10-20; Beta glucan, 10-20; Vitamin E, 10-20; Potassium diformate, 10-15; Vitamin B1,8-12; Vitamin B2,8-12; Vitamin B6,8-12; The pre-processing stage magnesium sulfate that contains magnesium 15%, 8-12.

Advantage of the present invention is: (1) can significantly slow down and stress, improve the cobio grazing rate, promotes growth; (2) survival rate of raising cobio complete period breed improves specific yield, increases the economic benefit that cobio is cultured.(3) improve the cobio meat quality, improve product quality, increase foreign exchange earnings from exports; (4) this Antistress agent its raw material source is stable, cheap, and production technology is simple.

The specific embodiment

Take by weighing vitamin C-2-phosphate, 20kg; Beta glucan, 15kg; Vitamin E, 15kg; Potassium diformate, 10kg; Vitamin B1,10kg; Vitamin B2,10kg; Vitamin B6,10kg; Pre-processing stage magnesium sulfate (containing magnesium 15%), 10kg.These raw materials are all pulverized in advance and are crossed 120 mesh sieves, mix then, are the cobio anti-stress feed addictive.

2005-2006 in Ningde, Fujian, the experiment in Zhanjiang, Guangdong shows, after this Antistress agent is promoted the use of, in cobio complete period breeding process, can effectively prevent cobio stress, effectively extenuated the cold current weather in the first half of the year and the loss that the typhoon rainstorm weather of the second half year brings to aquaculture.Cobio offshore cage culture complete period feed coefficient is respectively 1.1 and 1.2, reduces by 21.4% and 25.3% respectively than control group (being respectively 1.4 and 1.6); The cobio complete period cultures average survival and arrives more than 90%, and control group only is 78% or 70%.See the following form).

Zhanjiang, Guangdong, Ningde, Fujian cobio offshore cage culture experimental result (2005-2006)

Illustrate: " control group " usefulness be the cobio mixed feed (patent No.: ZL 03112115.2) that does not add anti-stress feed addictive, " add Antistress agent group ": the anti-stress feed addictive that has added 0.1-0.2% in the cobio mixed feed (patent No.: ZL 03112115.2).

Claims

1, a kind of cobio anti-stress feed addictive is characterized in that its component and percetage by weight scope are respectively: vitamin C-2-phosphate, 10-20; Beta glucan, 10-20; Vitamin E, 10-20; Potassium diformate, 10-15; Vitamin B1,8-12; Vitamin B2,8-12; Vitamin B6,8-12; The pre-processing stage magnesium sulfate that contains magnesium 15%, 8-12.
