CN101480231A - Composite feeding promoting agent for Rachycentron canadum - Google Patents

Abstract

The invention relates to a cobia compound phagostimulant which comprises ingredients by weight percentages (W/W): 20 to 30 percent of dimethyl-beta-propionate thetin, 15 to 20 percent of inosinic acid, 10 to 20 percent of trimethylamine oxide, 10 to 20 percent of taurine, 5 to 10 percent of glycine, 5 to 10 percent of alanine and 5 to 10 percent of glutamate. The invention has the advantages that the cobia compound phagostimulant functioning as the feed additive in cobia feed is added by 0.1 percent to 0.2 percent; the ingestion and the growth of cobia are obviously improved, and residual feed is reduced so as to be favorable to environmental protection; the amount of fishmeal in the feed can be greatly reduced, fishery resources are protected, and the feed cost is decreased. Raw materials used in the cobia compound phagostimulant have stable resources, low cost and simple production technology.

Description

A kind of cobio composite feeding promoting agent

Technical field

The present invention relates to a kind of feed addictive, particularly relate to a kind of cobio composite feeding promoting agent.

Technical background

Feeding promoting agent for fish and prawn is to be the theoretical foundation development with the sense of smell of fishes and shrimps and sense of taste physiology in conjunction with feeding behaviour, is meant fishes and shrimps to be attracted to around the food and to evoke its appetite and then short its class material of ingesting.Phagostimulant gathers around the feed it by sense of smell, the sense of taste and the vision etc. that stimulate fish and shrimp, accelerates to ingest, and improves feed intake.Feeding promoting agent for fish and prawn can improve the feed palatability, improves food ration and efficiency of feed utilization, can also alleviate water pollution in addition, thereby reduces the incidence of disease, the death rate of fish, increases economic benefit.

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.But up to the present, use about the research of cobio phagostimulant and yet there are no report, this popularization and healthy sustainable development of cobio aquaculture for cobio Effictive nuisancelless feed is disadvantageous.

Summary of the invention

The purpose of this invention is to provide a kind of cobio composite feeding promoting agent, it can remedy above-mentioned deficiency and promote the cobio aquaculture to develop in a healthy way.

The present invention is made up of dimethyl-β-DMPT, inosinicacid, TMAO, taurine, glycine, alanine and glutamic acid, and their percetage by weight (W/W) scope is respectively: 20-30,15-20,10-20,10-20,5-10,5-10 and 5-10.

The present invention has following advantage: use in the cobio feed as feed addictive (1), and addition only is 0.1-0.2%; (2) promote that obviously cobio ingests, promote growth; Reduce residual bait simultaneously, help protecting environment.(3) can reduce the consumption of fish meal in the feed significantly, protect fishery resourses, reduce feed cost; (4) its raw material source of the present invention is stable, cheap, and production technology is simple.

The specific embodiment

The present invention reduces environmental pollution simultaneously, promotes that the sound development of cobio aquaculture is significant for the efficiency of feed utilization that improves cobio, the range of choice that enlarges the cobio feedstuff, reduction feed cost.

Take by weighing dimethyl-β-DMPT 25kg, inosinicacid 15kg, TMAO 15kg, taurine 15kg, glycine 10kg, alanine 10kg, glutamic acid 10kg; these seven kinds of compositions are worn into fine powder (crossing 120 orders); in mixer, mix (requiring the coefficient of variation≤5%) then, be efficient composite feeding promoting agent of the present invention.Addition at mixed feed: 0.1%-0.2%.

2005-2007, the experiment in Hainan, Guangdong shows, (1) under the prerequisite that formulation cost equates, mixed feed complete period in offshore net cage, deep water wind wave-resisting net casing are cultured uses, throw something and feed and add the feed of this product, the comparison of cobio rate of body weight gain improves 17%-26% and 15%-25% respectively according to feed, and the feed coefficient comparison reduces 14%-20% and 12%-19% respectively according to feed, significantly promotes to ingest, improve growth.(2) fish meal reduction by 20%, feed cost reduce under the prerequisite of 400 yuan/ton (cost of material in 2007) in mixed feed, complete period uses in offshore net cage, deep water wind wave-resisting net casing are cultured, the feed (the cost comparison reduces by 400 yuan/ton according to feed) of throwing something and feeding and adding this product, cobio rate of body weight gain and feed coefficient and control feed are suitable, embody the effect that significantly reduces the fish meal consumption, reduces feed cost.

Claims (2)

1, a kind of cobio composite feeding promoting agent; it is characterized in that being made up of dimethyl-β-DMPT, inosinicacid, TMAO, taurine, glycine, alanine and glutamic acid, their percetage by weight (W/W) scope is respectively: 20-30,15-20,10-20,10-20,5-10,5-10 and 5-10.

2, according to the addition of the described a kind of cobio composite feeding promoting agent of claim 1 at mixed feed: 0.1%-0.2%.
