Description

A kind of Pelteobagrus vachelli adult fish pellet

Technical field

The present invention relates to the animal-breeding technical field, particularly relate to a kind of Pelteobagrus vachelli adult fish pellet.

Background technology

China is world fresh water fishery big country, and it is 1,998 ten thousand tons that China freshwater fish in 2008 is cultured total output, accounts for 70 % of China's fish total output.Because of the execution in marine fishing zero growth policy and closed fishing season, China's seawater fish output tends towards stability at present, and freshwater fish output but presents sustainable growth, and the fresh-water fishes industry is subjected to showing great attention to of society.Do not have high-caliber feed industry, just do not have the aquaculture of healthy and sustainable development.What developed country was long-term facts have proved: the contribution rate of the Application and Development of nutrient research and feed in aquaculture development is about 40%.China's aquatic feeds in 2008 is 2,000 ten thousand tons of less thaies also, all the other all rely on feeding raw material or iced trash fish directly to throw something and feed, not only significant wastage the limited feed resource of China, and cause severe contamination, disease to grow to water environment, the harm food sanitation safe threatens the sustainable development of China's culture fishery.Therefore, safe and efficient, the oligosaprobic nuisanceless mixed feed of research and development is the trend of domestic and international fishing with the feed technology development.

Pelteobagrus vachelli ( Pelteobagrus vachelli)), have another name called pseudobagrus vachelli, it is a kind of main small-sized economic fish that the Changjiang river, reservoir area of Three Gorges Heavenly Stems and Earthly Branches stream extensively distributes, also be the main catches of waters, reservoir area, present Yangtze River Gorges fish, sting between, muscle fat content height abundant, fresh and tender, the no flesh of meat flavour etc. and liked by the consumer, in recent years because of its amino acid content, its market price is high always, price remains on every kilogram of 24-32 unit for a long time, has become high-grade well sold and in short supply freshwater fish, has higher culture benefit.Because the Pelteobagrus vachelli growth phase is to slowly, the hysteresis of artifical compound feed preparation technique in addition causes the low or muscle color and luster variation of cultivation of fish grow speed, thereby has a strong impact on breed and the economic benefit of its adult fish.Therefore, developing effective artifical compound feed is to promote a cultured fishes important step of growth fast.

Summary of the invention

The objective of the invention is to overcome the above-mentioned defective that prior art exists, a kind of Pelteobagrus vachelli adult fish pellet is provided.

A kind of Pelteobagrus vachelli adult fish of the present invention pellet, its component and quality percentage composition are as follows:

Peeling dregs of beans 25～30%, rapeseed dregs 20～25%, cotton dregs 15～20%, flour 15～20%, steam fish meal 5～10%, corn protein powder 3～5%, low temperature dusty yeast 2～5%, seawood meal 1～3%, soybean lecithin 1～3%, fish oil 1～3%, bacillus subtilis 0.1～0.3%, vitamin C 0.1～0.3%, zinc methionine 0.03～0.05%, ethoxyquinoline 0.05～0.08%.

The preparation method of a kind of Pelteobagrus vachelli adult fish of the present invention pellet is simple: take by weighing each component, pulverize respectively, cross 60 mesh sieves, mix with soybean lecithin, fish oil, granulate then, promptly obtain pellet of the present invention.

Pellet of the present invention is good at water stability, and dissolve-loss ratio is low, and is little to water pollution; Can obviously improve the color and luster of Pelteobagrus vachelli, promote that sashimi (raw fish) is long; And its raw material source is stable, and cheap, production technology is simple; The mass percent of contained protein and fat is respectively 32～36% and 4～7%.

The specific embodiment

Embodiment 1:

Take by weighing peeling dregs of beans 28 kg, rapeseed dregs 22 kg, cotton dregs 16 kg, flour 15.72kg, steam fish meal 7 kg, corn protein powder 3 kg, low temperature dusty yeast 3 kg, seawood meal 2 kg, bacillus subtilis 0.1 kg, vitamin C 0.1 kg, zinc methionine 0.03 kg and ethoxyquinoline 0.05 kg, above each component is pulverized respectively, cross 60 mesh sieves, mix with 1kg soybean lecithin, 2kg fish oil again, granulate then, obtain pellet of the present invention.

In national zones of different two place test site indoor circulation cultivating system, the initial weight of Pelteobagrus vachelli is 12.4 ± 1.2 g, control group adopts the best commercial feed of culture efficiency in the market, and the used feed of experimental group adopts above-mentioned Pelteobagrus vachelli adult fish pellet.The feeds utilized protein content of control group and experimental group is identical, is the 36%(mass percent), and all divide into 3 repetitions.Through learning behind 56 days the raising experiment, the specific growth rate of the Pelteobagrus vachelli of the feed of the present invention of throwing something and feeding is 2.38%/sky ~ 2.52%/sky, is significantly higher than the control group (1.95%/sky ~ 2.13%/sky) that adopts commercial feed; The liver fat content of experimental group Pelteobagrus vachelli is 7.15%, significantly is lower than commercial feed group (9.38%); The muscle color and luster of experimental group Pelteobagrus vachelli than commercial feed group more near the color and luster of its spontaneous growth, i.e. back pitchy, the side yellow, belly is faint yellow.And, adopt liver pancreas glutamic-pyruvic transaminase (GPT), glutamic-oxalacetic transaminease (GOT) and superoxide dismutase (SOD) vigor (the 86.36 U g of the Pelteobagrus vachelli of above-mentioned experiment feed ^-1Albumen, 115.98 U g ^-1Albumen and 62.35 U mg ^-1Albumen) all be significantly higher than commercial feed group (61.35 U g ^-1Albumen, 87.24 U g ^-1Albumen and 34.68 U mg ^-1Albumen).

Embodiment 2:

Take by weighing peeling dregs of beans 25 kg, rapeseed dregs 23 kg, cotton dregs 15 kg, flour 16.5kg, steam fish meal 9 kg, corn protein powder 3.5 kg, low temperature dusty yeast 2.5 kg, seawood meal 1.5 kg, bacillus subtilis 0.2 kg, vitamin C 0.2 kg, zinc methionine 0.05 kg and ethoxyquinoline 0.05 kg, above each component is pulverized respectively, cross 60 mesh sieves, mix with 2kg soybean lecithin, 1.5kg fish oil again, granulate then, obtain pellet of the present invention.

Two places carry out the land for growing field crops culture experiment in national zones of different, the initial weight of Pelteobagrus vachelli is 17.6 ± 1.8 g, the culture experiment of two place fishes and the experiment of control group are carried out on 3 mouthfuls of pools respectively, the average area on every mouthful of pool is 6 mu, the feed that control group is used adopts the best commercial feed of culture efficiency on the market, the feed that experimental group is used adopts above-mentioned Pelteobagrus vachelli adult feedstuff of the present invention, and the content of albumen is identical in two kinds of feeds, is the 34%(mass percent).Behind 60 days raising experiment, the growth rate of Pelteobagrus vachelli of the experiment feed of throwing something and feeding is 2.86%/day ~ 2.92%/day, be significantly higher than control group with commercial feed (2.69%/day ~ 2.76%/day); The feeds utilized feed coefficient (1.62 ~ 1.65) of experimental group significantly is lower than commercial feed group (1.71 ~ 1.78).And, adopt muscle color and luster, liver fat content and liver pancreas glutamic-pyruvic transaminase (GPT), glutamic-oxalacetic transaminease (GOT) and superoxide dismutase (SOD) the vigor index of the Pelteobagrus vachelli of above-mentioned experiment feed all to be better than the commercial feed group.

The present invention not only can promote the growth of Pelteobagrus vachelli, reduces aquaculture cost, can also protect Upper Yangtze River Pelteobagrus vachelli germ plasm resource, keeps the sustainable development of Pelteobagrus vachelli aquaculture.
