Abstract
The composite micro ecological preparation for prawn consists of live bacteria bead and carrier, and features that the live bacteria bead contains Bacillus subtilis in 1-2 billion CFU/g, Bacillus licheniformis in 0.5-10 billion CFU/g, double microcapsule coated lactic acid bacterian in 0.3-0.5 billion CFU/g, and double microcapsule coated tobacco arthrobacter in 0.2-0.5 billion CFU/g, with the total live bacteria being in the range of 2-4 billion CFU/g. The present invention has the advantages of: small added amount of 0.1-0.2 %, obvious effect of raising immunity and survival rate of prawn, obvious function of raising the digestion and absorption of prawn and lowering the feed coefficient, no bad effect on the taste of feed, stable material source, low cost and simple production process.
Description
Technical field
The present invention relates to a kind of fodder additives, particularly relate to a kind of prawn and use compound micro-ecological preparation.
Background technology
Because problems such as drug residue and bacterial drug resistances, the cry that limits the microbiotic use in the world is more and more higher.In feed, improve the immunizing power of aquatic animal, can reduce antibiotic use like this by adding probiotics (active bacteria formulation).Since the nineties in 20th century, the existing both at home and abroad many reports of the application of the probiotics of single bacterial strain on aquatic products, but find that in actual applications the probiotics of single bacterial strain often action effect is limited, is difficult to satisfy the actual needs of prawn culturing.
Summary of the invention
The purpose of this invention is to provide a kind of prawn and use compound micro-ecological preparation, it can overcome the above-mentioned shortcoming of existing single composition probiotics.
A kind of prawn is used compound micro-ecological preparation, formed by viable bacteria pearl and carrier, it is characterized in that described viable bacteria pearl has subtilis, 10-20 hundred million CFU/g, Bacillus licheniformis, 5-10 hundred million CFU/g, through the milk-acid bacteria of bilayered microcapsule bag quilt, 3-5 hundred million CFU/g are through the tobacco Arthrobacter of bilayered microcapsule bag quilt, 2-5 hundred million CFU/g, total viable count scope is 20-40 hundred million CFU/g.
The present invention has following advantage: use in prawn feed as fodder additives (1), and addition only is 0.1-0.2%; (2) obviously strengthen the immunity of organisms of prawn, improve surviving rate; (3) significantly improve the prawn digestibility, promote growth, reduce feed coefficient; (4) the present invention does not have any detrimentally affect for the palatability of feed; (5) all there is sale the used raw material domestic market of the present invention, steady sources, and cheap, production technique is simple.
Embodiment
Take by weighing the former powder of subtilis (1,000 hundred million CFU/g) 1.5kg, the former powder of Bacillus licheniformis (1,000 hundred million CFU/g) 0.75kg, through the former powder of milk-acid bacteria (the 20000000000 CFU/g) 2.25kg of bilayered microcapsule bag quilt, through the former powder of tobacco Arthrobacter (the 20000000000 CFU/g) 1.5kg of bilayered microcapsule bag quilt, take by weighing carrier (beer yeast powder) 94kg in addition and above-mentioned four kinds of former powder are made into 100kg.These four kinds of former powder and carrier are mixed (requiring the variation coefficient≤5%) in mixing machine, be prawn of the present invention and use compound micro-ecological preparation.Product viable bacteria total content of the present invention is 3,000,000,000 CFU/g; Wherein: subtilis, 1,500,000,000 CFU/g; Bacillus licheniformis, 7.5 hundred million CFU/g; Through the milk-acid bacteria of bilayered microcapsule bag quilt, 4.5 hundred million CFU/g; Through the tobacco Arthrobacter of bilayered microcapsule bag quilt, 300,000,000 CFU/g.
The applicant studies show that, the bacterial strain that will have different efficacies is mixed with compound micro-ecological preparation by certain compatibility, can make and show the obvious synergistic effect between the different strains, improves action effect greatly.
The present invention shows in the shop experiment of Chinese prawn, tigar prawn and Environment of Litopenaeus vannamei Low, adds product of the present invention (shrimp happy 333) 1.0-2.0g/kg in the feed, just can significantly promote the prawn growth, reduces feed coefficient; Significantly improve prawn immunizing power, 5 kinds of main immune indexes of prawn (hemocyte phenoloxidase activity, alkaline phosphatase activities, respiratory burst activity, hemocyte sum and activate the phagocytic capacity etc.) improve 1.5-4.6 doubly than control group.
The smart shrimp-cultivation pool experimental result of the 50 mu of high positions in Qionghai in 2004: the prawn surviving rate improves 18.2%, and feed coefficient 1.04 reduces by 17.3% than control group.Zhuhai, Guangdong 100 mu of common shrimps pond reconnaissance test-results shows that the prawn surviving rate improves 19.3%, and feed coefficient 1.01 reduces by 18.7% than control group.
The smart shrimp-cultivation pool experimental result of the 120 mu of high positions in Longhai City, Fujian in 2004: the prawn surviving rate improves 21.8%, and feed coefficient 1.09 reduces by 20.8% than control group.Zhanjiang, Guangdong 100 mu of common shrimps pond reconnaissance test-results shows that the prawn surviving rate improves 18.2%, and feed coefficient 1.0 reduces by 19.2% than control group.
The smart shrimp-cultivation pool experimental result of the 120 mu of high positions in Nanhui, Shanghai in 2004: the prawn surviving rate improves 17.2%, and feed coefficient 1.01 reduces by 16.3% than control group.The North Sea, Guangxi 160 mu of common shrimps pond reconnaissance test-results shows that the prawn surviving rate improves 18.9%, and feed coefficient 0.97 reduces by 15.4% than control group.
In addition, outdoor field experiment also shows, adds product 1.0-2.0g/kg of the present invention in the feed, can significantly improve the content of genus bacillus in tigar prawn aquaculture water, enteron aisle and the ight soil, suppresses the propagation of vibrios (Vibrio spp.).
