[summary of the invention]
The purpose of this invention is to provide and a kind ofly can use, have prevention Tilapia mossambica streptococcosis function and artifical compound feed balanced in nutrition culturing high temperature season.
For achieving the above object, the technical solution used in the present invention is as follows:
A kind of artifical compound feed with prevention Tilapia mossambica streptococcosis function, calculate by percentage to the quality, comprise fish meal 1-5%, dregs of beans 20-30%, dish dregs of rice 20-30%, cotton dregs 10-15%, DDGS (the dry thing of maize alcohol lees and raffinate): 10-15%, rice bran 5-10%, flour 15-20%, corn 5-10%, soya-bean oil 1-2%, phosphatide oil 0.5-1.5%, calcium monohydrogen phosphate 1-2%, bentonite 1-10%, many ore deposits of multidimensional pre-composition 0.5-1%, Choline Chloride 0.1-0.5%, antioxidant 0.01-0.05%, mould inhibitor 0.1-0.5%, compound Chinese medicine additive 1-5%.
Preferably, calculate by percentage to the quality, comprise fish meal 2-5%, dregs of beans 20-30%, dish dregs of rice 20-30%, cotton dregs 10-15%, DDGS (the dry thing of maize alcohol lees and raffinate): 10-15%, rice bran 5-10%, flour 15-20%, corn 5-10%, soya-bean oil 1-2%, phosphatide oil 0.5-1.5%, calcium monohydrogen phosphate 1-2%, bentonite 1-10%, many ore deposits of multidimensional pre-composition 0.7%, Choline Chloride 0.2%, antioxidant 0.01-0.05%, mould inhibitor 0.1-0.5%, compound Chinese medicine additive 1-3%.
Albumen, energy, vitamin and mineral raw material adopt prior art in the feed, wherein, described compound Chinese medicine additive is with after mixing in Radix Codonopsis 10-20 part, Radix Isatidis 5-15 part, Herba Andrographitis 5-15 part, honeysuckle 5-15 part, rhizoma menispermi 5-15 part, coptis 5-15 part, golden cypress 5-15 part, rheum officinale 5-15 part, Radix Astragali 5-15 part of weight portion, pulverize with micronizer, smashing fineness reaches 100 orders.
With mixing in proportion after the above-mentioned raw materials pulverizing,, make tilapia feed after the extruding cutting by conventional feed machinery.
Compare with common tilapia feed, the present invention has following advantage: 1, the nitrogen of feed can be than balance, and Tilapia mossambica is to its digestibility height, can not cause in the water ammonia nitrogen too high and bring out the streptococcus outburst; 2, add multiple antibacterial Chinese herbal medicines additive in the feed, improved the antibacterial ability of Tilapia mossambica, can effectively prevent the generation of Tilapia mossambica streptococcosis.
[specific embodiment]
The invention will be further described below in conjunction with specific embodiment.
Embodiment 1
According to the mass percent meter, take off the feedstuff of stating after the pulverizing: fish meal 5%, dregs of beans 22%, the dish dregs of rice 20%, cotton dregs 10%, DDGS (the dry thing of maize alcohol lees and raffinate) 10%, rice bran 5%, flour 15%, corn 6%, soya-bean oil 1.2%, phosphatide oil 0.5%, calcium monohydrogen phosphate 1%, bentonite 1.79%, many ore deposits of multidimensional pre-composition 0.7%, Choline Chloride 0.2%, antioxidant 0.01%, mould inhibitor 0.1%, compound Chinese medicine additive 1.5%.The compound Chinese medicine additive is after 15 parts of mixing of 15 parts of 10 parts of 10 parts of 10 parts of 10 parts of 10 parts of 10 parts of 15 parts of Radix Codonopsis, Radix Isatidis, Herba Andrographitis, honeysuckles, rhizoma menispermis, the coptiss, golden cypresses, rheum officinales, the Radix Astragali in weight portion, form with the micronizer pulverizing, smashing fineness reaches 100 orders.After raw material fully mixes,, make tilapia feed after the extruding cutting by feed manufacturing machine.
Present embodiment forage protein content is: 30%, and fat content is: 3.8%.
Present embodiment adopts attacks malicious the checking, and three groups are established in experiment, and 5 every group parallel.Three feeds utilized common Tilapia mossambica commercial feed a, common Tilapia mossambica commercial feed b, embodiment of the invention feeds of being respectively of group.Experiment is carried out in aquarium.The experiment beginning, it is approaching to put into size specification in each aquarium, and each 30 tail of the Tilapia mossambica of physical health, every urosome weigh about 6 grams.The total body weight difference of Tilapia mossambica restrains less than 1 in each aquarium.Experiment divides three phases to carry out.Stage one: 1 month by a definite date throw something and feed the stage, 9 of every mornings and afternoon 3 feeds Tilapia mossambica of feeding with correspondence, adopting is satiated with food throws something and feeds the feeding volume unanimity of each aquarium.Stage two: injection stage is 8 * 108 Streptococcus iniae bacterium liquid (take out purifying in the Tilapia mossambica body of bacterium liquid bacterial strain uses therefor by the death of trouble streptococcosis and cultivate acquisition) 1ml to every tail Tilapia mossambica injection concentration.Stage three, one month by a definite date observation stage, the Tilapia mossambica that continues to throw something and feed each experimental group by described method of stage one, observed and recorded Tilapia mossambica death condition simultaneously.Final experimental result statistics is as follows:
Experimental results show that the medicinal herb components that contains in the feed provided by the invention has antibacterial action, can effectively prevent the generation of Tilapia mossambica streptococcosis, reduce the injury of streptococcosis Tilapia mossambica.
The prescription of testing used Tilapia mossambica commercial feed a is: calculate by percentage to the quality and comprise fish meal 2%, dregs of beans 35%, the dish dregs of rice 35%, rice bran 10%, flour 14%, soya-bean oil 1%,, calcium monohydrogen phosphate 1%, bentonite 1%, many ore deposits of multidimensional pre-composition 0.7%, Choline Chloride 0.2%, antioxidant 0.1%.
The prescription of Tilapia mossambica commercial feed b: calculate by percentage to the quality, comprise fish meal 2%, dregs of beans 30%, the dish dregs of rice 40%, rice bran 14%, flour 10%, soya-bean oil 1%,, calcium monohydrogen phosphate 1%, bentonite 1%, many ore deposits of multidimensional pre-composition 0.7%, Choline Chloride 0.2%, antioxidant 0.1%.
