Abstract
A phagostimulant of prawn for decreasing the cost of its feed by using it as the additive of feed is proportionally prepared from dimethyl-beta-thetin propionate, hypoxanthine nucleotide, taurine, glycine and glutamic acid.
Description
Technical field
The present invention relates to a kind of feed addictive, particularly relate to a kind of prawn bait that helps reducing feed cost.
Background technology
China's shrimp culture industry is after the serious blow of having experienced explosive disease of phase earlier 1990s, and it is flourish to have got back since middle nineteen nineties.Now, prawn culturing had become the pillar industry of China's mariculture already, and prawn feed has occupied the share of China's marine cultured animal manufactured feed more than 80% especially.Along with the fast development of breed scale, prawn output increases year by year, so the prawn price has glided into an irresistible trend.For this reason, reducing the prawn culturing cost by the reduction feed cost is the important problem of pendulum in face of the aquatic science and technology worker.Will fundamentally reduce the cost of prawn feed just must select for use other animal and plant protein sources partly to substitute the fish meal that price is high, supply growing tension.Yet fish meal content reduces and can cause again that the feed palatability is poor, animal feed intake descends.Therefore, this just need develop out effective prawn bait.
Summary of the invention
The purpose of this invention is to provide a kind of prawn bait, it can promote the ingest manufactured feed of low fish meal of prawn, reduces feed cost, keeps the shrimp culture industry sustainable development.
A kind of prawn bait; it is characterized in that being made up of dimethyl-β-DMPT (DMPT), inosinic acid, taurine, glycine, glutamic acid, their percetage by weight scope is respectively: 20-30,15-25,15-25,10-20 and 10-20.
The present invention has following advantage: use in prawn feed as feed addictive (1), and addition only is the 0.1-0.2% of feed weight; (2) obviously promote prawn to ingest and grow; Reduce residual bait simultaneously, help protecting environment.(3) can reduce the consumption of fish meal in the feed significantly, reduce feed cost; (4) its raw material source of the present invention is stable, cheap, and production technology is simple.
Embodiment
Take by weighing dimethyl-β-DMPT (DMPT) 25kg, inosinic acid 20kg, taurine 20kg, glycine 18kg, glutamic acid 17kg; these five kinds of compositions are worn into fine powder (crossing 200 orders); in mixer, mix (requiring the coefficient of variation≤5%) then, be prawn bait of the present invention.Adding prawn bait of the present invention in low-cost prawn feed not only can make animal obtain feed in the short period of time and the bait behavior is taken the photograph in promotion, reduce food consumption, and bait can also promote the secretion of digestive ferment, enlivens digestion and the absorption function of shrimp, thereby promotes the prawn growth.
(initial weight: 0.82 ± 0.02g) cultures to carry out Environment of Litopenaeus vannamei Low 18 days～August 6 May in 2002 in East Sea Island, Zhanjiang, Guangdong indoor circulation system, do not add prawn bait of the present invention in the control group feed (3 repetitions), contain 40% high-quality red fish meal in this feed formula.Add 0.1% in experiment feed (3 repetitions) the prawn bait (product of the present invention) of (percetage by weight, down with), fish meal content reduced for 30% (promptly containing 28% fish meal) than control group.After 80 days raising experiment finished, the prawn average survival of the experiment feed of throwing something and feeding was 98.5%, and average growth rate is 1210%, does not have significant difference (the average survival rate and the rate of body weight gain of control group are respectively 96.8% and 1249%) with control group; And the price comparison of experiment feed has reduced 180-250 unit/ton according to feed.
Carry out Environment of Litopenaeus vannamei Low land for growing field crops culture experiment 2 days～August 3 May in 2003 in Zhuhai, Guangdong, the control group feed does not add prawn bait of the present invention in (3 mouthfuls of pools, every mouthful of pool average area is 12 mu), contains 40% high-quality red fish meal in the feed formula.Add 0.1% prawn bait (product of the present invention) in the experiment feed (3 mouthfuls of pools, every mouthful of pool average area is 12 mu), fish meal content reduced for 30% (promptly containing 28% fish meal) than control group.After 90 days raising experiment finishes, the prawn per mu yield 1019kg of the experiment feed of throwing something and feeding, feed coefficient 1.02 does not have significant difference (per mu yield of control group and feed coefficient are respectively 1005kg and 1.04) with control group; And the average price of experiment feed is 5050 yuan/ton, and 5280 yuan/ton of control feed are 5.15 yuan/kilogram with the feed cost of testing the feed cultured prawn, and comparison reduces by 6.6% according to feed (5.49 yuan/kilogram).
Claims (1)
1, a kind of prawn bait is characterized in that being made up of dimethyl-β-DMPT, inosinic acid, taurine, glycine, glutamic acid, and their percetage by weight scope is respectively: 20-30,15-25,15-25,10-20 and 10-20.
