Clinical testing and clinical verification

Raise the test report of Europe eel

Test objective: Chinese herbal feed additive of the present invention can improve the production performance of multiple animal, also can accelerate the growth of fish, and for further verifying its effect, the inventor carries out feeding trial in July, 2000 to different size Europe eel.

Materials and methods: when common eel sorts, select the close common eel of specification to be divided into test group and control group, test feed is a underlying commodity bait, adds 0.2% additive of the present invention (being that per kilogram bait adds 2 grams).Control group adds antibiotic.About test period 40 days.Duration of test, the aquaculture management of test group and control group is the same.Observe active state and record feed consumption situation every day.

Result of the test:

Analyze and brief summary

1, add 2 ‰ additive fish growth speed of the present invention in feed and on average improved 11.9, the speed of growth of shrimps has improved 12%, and crab has improved 20.8%, and soft-shelled turtle has improved 6.2%.The most remarkable with heterophagous Colossoma brachypomum amplification especially in the fish, reach 35.5%.

2, additive of the present invention helps strengthening the physique of breed variety as feed addictive, and in the pilot fish, the survival rate of test group all is 100%, and the bream of control group then is 95%; The shrimps test has proved that also this point, the survival rate average out to 71.3% of test group, control group then are 68.0%; The survival rate difference of crab test is more obvious, and test group is 78.0%, and control group then is 70.7%.

3, use additive of the present invention, feed coefficient obviously reduces, and in pilot fish, the feed coefficient control group of four kinds of fishes is 1.7, and test group has only 1.3, feed coefficient reduces by 0.4, and promptly 23.5%, the range of decrease is appreciable, the feed coefficient of control group is 3.1 in the shrimps test, test group is 2.6 then, has reduced by 0.5, decreases by 16.1%; In the crab test, the feed coefficient of control group is 2.9, and test group is 2.7, has reduced by 0.2, and the range of decrease is 6.9%; In the soft-shelled turtle test, feed coefficient descends 0.5, and the range of decrease is 20.8%.Above-mentioned four tests, feed coefficient has on average descended 16.8%.

4,, can draw as drawing a conclusion according to above-mentioned feeding trial to 8 kinds of aquaculture kinds:

A, additive of the present invention can promote growth, significantly improve weightening finish, both have been applicable to special aquatic products animals such as crab, shrimps and soft-shelled turtle, also are applicable to common fish;

B, obviously improve the premunition of aquatic livestock, help the healthy growth of aquatic livestock, and can in disease prevention and cure, replace antibiotic;

C, significantly improve efficiency of feed utilization, reduce feeding cost by a relatively large margin;

D, this product are pure natural plant extract, by replacing artificial synthetic additive, help avoiding the medicament residue problem in the aquatic products, are a kind of green feed additives that is worthy to be popularized.

Raise the test report of pond crucian carp fish

Test objective:, carry out the contrast test of this product in certain fishing ground, effect district on September 14,18 days to 2002 April in 2002 in order to confirm the effect of additive of the present invention in aquaculture.

Test material and method

The silver Carassius auratus feed is a control group, and test group is added 2 ‰ additives of the present invention on control basis, do not add antibiotic in the test group.Feed formula adopts U.S. Brill feed formula software that optimization of C is provided, and pellet is processed by near processing space.

The selection of growing seedlings: select healthy pond crucian carp 2400 tails (189.6 kilograms of gross weights), adopt all to claim method it to be divided into control group and test group, every group of three repetitions, each repeats 400 tails.

The selection in fishpond and preparation: according to the fish-culture test requirement, select 900 square metres (long 42 meters, wide 22 meters), water source irrigation and drainage are convenient, surrounding environment is consistent, smooth at the bottom of the cement pool wall, pond, fishpond that mud is few, (flow through with the close basketry of thin bamboo strips used for weaving with water, can not cross fish is as the criterion) all separate and block into six little fishponds, 150 square metres of each little pool areas, about 0.8 meter of the depth of water; For keeping fishpond water level and the oxygenation of water irrigation and drainage miniflow, in each Xiao Chi lower-left.

The bait throwing in technology: bait is pressed into granular bait for fish according to testing program and bait preparation.Daily ration, feeding quantity, every group of every day be all by the bait of fry body weight 3%～5%, takes by weighing quantitative feed, fixed point is thrown something and fed, every 10 days dosages once.Every day is respectively at 9 o'clock in the morning, afternoon 6～7 o'clock in the fishpond fixedly the bait throwing in point throw something and feed twice, each group is write down the pellet feeding volume respectively.

Test event: two groups of fries are fed and finished test simultaneously in 150 days, and fishpond water is put totally, and group is caught clean, and statistics is respectively organized feed consumption rate, weightening finish.

The result of the test statistics: indexs such as statistics weightening finish, feed coefficient, inventory, the death rate and economic benefit, analyze with the SPSS statistical software.

Result of the test

Gaining effect: the test group control group 43.3kg that increases weight more, growth rate is 24.78%, difference is (P＜0.01 extremely significantly.

Feed coefficient: control group and degree test group feed coefficient be respectively 1.90 and 1.81, test group reduces by 4.74% than control group, significant difference (P＞0.05.

Survival rate: test group and control group survival rate are divided into 98%, 94%.Test group improves 4% than control group, significant difference (P＞0.05.

Economic benefit: test group and control group net profit are respectively 573.7 yuan and 353.3 yuan, and test group increases by 220.4 yuan than control group, and amplification reaches 62.4%, and difference is P＜0.01 extremely significantly.

Conclusions and recommendations

Use additive of the present invention in the pond crucian carp fish meal, reducing pond crucian carp fish disease, reduce feed coefficient, it is obvious to improve weightening finish and economic benefit aspect effect, and test group is individual neat, and scale is more glossy, and vigor strengthens.
