Abstract
The invention discloses a freshwater fish feed additive and a production method thereof. According to the feed additive provided by the invention, components are prepared reasonably, processing is convenient, cost is lower, and decomposition speed is high; decomposition speed and utilization speed of urea in the feed additive are coordinated, ammonia poisoning caused by ammonia accumulation in blood is avoided, and the defect of poor palatability of conventional feed is overcome; the feed additive is ground by a colloid grinder, emulsion is formed and dried in a spray dryer at the normal temperature to form microspheres, microspheres are taken as the feed additive, and powder, granules, tablets or capsules can also be prepared from the microspheres; the feed additive is applicable to aquatic creatures such as freshwater fish, shrimps and the like.
Description
Technical field
The invention belongs to aquatic animal feed technical field, and in particular to a kind of fresh water fish feed additive and its production method.
Background technology
The characteristic of ammonia can be utilized using microorganism in fresh water fish body, often application nonprotein nitrogen replaces protein feeds in fresh water fish feed, to save protein resource.Fish meal has the advantages that nitrogen content is high, low production cost, is the nonprotein nitrogen source of highly deep development.Research has shown that, fish-meal can breed rapid microbial growth, and fresh-water fishes can substantially increase feed intake 15~20% after feeding, improve digestibility 20%.However, fish meal is just rapid after entering hydrolyzing, there is ammonia to discharge at once, blood is entered by body, and its rate of release just causes animal ammonia poisoning often more than the utilization speed of internal microorganism when the ammonia amount for entering blood exceedes liver detoxification ability.And existing feed have palatability difference the characteristics of, the repulsion behavior of aquatic animal may be caused.The defect of the aquatic equal various degrees of class feed product applied in the market, it is impossible to properly settle feed problem present in application process, popularization and application of the influence feed in fish production.
The content of the invention
In order to solve above-mentioned deficiency, it is an object of the invention to provide a kind of fresh water fish feed additive and its production method, the feed addictive decomposition rate is mutually coordinated with using speed, it is to avoid ammonia is accumulated in blood causes ammonia poisoning, while solving the shortcoming of conventional feed palatability difference.
The technical scheme adopted by the invention to solve the technical problem is that：The present invention provides a kind of Nonprotein nitrogen feed additive and its component of production method suitable for fresh-water fishes, is formulated by following components, (percentage by weight)
Calcium carbonate
5~10%
Fish meal 30~50%
Cornstarch 30~40%
Coating material 2~20%
Coating material therein may be selected from least one or combinations thereof in gelatin, sodium carboxymethylcellulose, ethyl cellulose, PVP, Carbomer.
The present invention provides the preparation technology of a kind of fresh water fish feed additive and its production method：
The fish meal and cornstarch of actual specific gravity are uniformly dispersed in coating material solution, emulsion is ground to form through colloid mill, put at normal temperatures and be dried to microballoon in spray dryer, as feed addictive, may be made as powder or granule, tablet, capsule etc..
The beneficial effects of the invention are as follows：The preparation technique of ultramicro grinding, microencapsulation and miniature balling-up is used in production technology, fish meal is made microballoon of the diameter between 40-100um, make its rate of release in fresh water fish body slow and continue, mutually coordinate with other utilization speed, decomposition rate is too fast in vivo to solve the problems, such as fish meal, can be prevented effectively from animal ammonia poisoning；Granulation quality is improve using spray drying technology, gained grain graininess is uniform, inclusion is abundant, inserts the peculiar taste of the imperceptible fish meal of animal in aquatic animal feed, it is easy to edible.The selected equal safety non-toxic noresidue of coating material, will not damage in metabolic process to animal body.In process of production, all operations are completed under normal temperature condition, do not result in nuisance decomposition, reduce the loss of raw material.And in actual production, manufacturer can be made the different dosage forms such as the powder or granule, tablet, capsule of suitable needs as desired by adding the auxiliary materials such as starch further to mix in obtained fish meal microballoon, substantially increase practicality of the invention；Suitable for the feed addictive of the aquatic animals such as fresh-water fishes, shrimp.
Calcium carbonate is added, calcium can be supplemented to fresh-water fishes, promote aquatic animal growth.
Specific embodiment
The component of a kind of fresh water fish feed additive and its production method, is formulated by following components, (components by weight percent)
Embodiment 1
Formula：Calcium carbonate 80g, fish meal 500g, cornstarch 480g, gelatin 20g
Preparation method：Fish meal and cornstarch are uniformly dispersed in gelatin solution, emulsion is ground to form through colloid mill, put be dried to microballoon in spray dryer at normal temperatures, obtain final product a kind of fresh water fish feed additive of the invention.May be made as powder or granule, tablet, capsule etc..
Embodiment 2
Formula：Calcium carbonate 90g, fish meal 500g, cornstarch 450g, sodium carboxymethylcellulose 50g
Preparation method：It is completely the same with embodiment 1.
Clinical practice example：10 fishing ground feedings are closely carried out to Jiangsu Province TAI HU AREA with Nonprotein nitrogen feed additive produced by the present invention.None example produces malaise symptoms, and fresh water fish crop steadily increases, and protein content is improved；Fresh-water fishes meat palatability is improved.
Claims (2)
1. a kind of fresh water fish feed additive and its production method, it is characterised in that including calcium carbonate, fish meal, cornstarch, coating material；It is characterized in that：It is formulated by following components, (percentage by weight) calcium carbonate 5~10%, fish meal 30~50%, cornstarch 30~40%, coating material 2~20%；Coating material therein may be selected from least one or combinations thereof in gelatin, sodium carboxymethylcellulose, ethyl cellulose, PVP, Carbomer.
2. a kind of a kind of fresh water fish feed additive as claimed in claim 1 and its production method；It is characterized in that：Preparation technology is：The calcium carbonate of actual specific gravity, fish meal and cornstarch are uniformly dispersed in coating material solution, emulsion is ground to form through colloid mill, put be dried to microballoon in spray dryer at normal temperatures, as feed addictive, be made powder or granule, tablet, capsule.
