Abstract

The invention discloses biological fermented feed for increasing the growth speeds and improving the immunity of freshwater shrimps. Corn flour, potato flour, fishbone meal, pork powder, bagasse, fermented cottonseed meal and rapeseed meal are used as fermentation substrates, mixed bacterium solid fermentation modes are adopted, and mixed bacteria include enterococcus faecium, lactobacillus acidophilus, rhodopseudomonas palustris, aspergillus oryzae and lactobacillus fermentium. Fermentation processes include that the additive amount of ammonia water is 1%, the inoculation amount is 1%, the fermentation temperature is 32 DEG C, the fermentation time is 40 h, and the thicknesses of the substrates are 30 cm. The biological fermented feed has the advantages that the feed fermented by the aid of the processes has high nutritional value and is good in palatability, the growth speeds of the freshwater shrimps can be effectively increased, and the immunity of the freshwater shrimps can be effectively improved.

Description

A kind of biological fermentation feed for improving the fresh water shrimp speed of growth and immunity

Technical field

The present invention relates to a kind of feed, sends out in particular to the biology of a kind of raising fresh water shrimp speed of growth and immunity Ferment feed.

Background technology

In recent years, the culture fishery of China is developed rapidly, but by the factor such as high-density breeding and excessive bait throwing in Impact, the aquatic livestock growing environment of China constantly deteriorates.At present using antibiotic and disinfectant come prevention and control shrimp, crab Disease has become common technological means, but with being on the rise the problems such as the drug-fast enhancing of pathogen and medicament residue, Change intrinsic prevention from suffering from the diseases has become the task of top priority, and applied nutrition immunology principle to improve aquatic livestock with treatment method Premunition have been considered as realizing nuisanceless ecologic breeding and guarantee the effective means of culture fishery sustainable development, be worth Carry out in-depth study and inquire into.

The content of the invention

In order to solve the above problems, the invention provides a kind of biofermentation for improving the fresh water shrimp speed of growth and immunity Feed, specific design scheme is：

With corn flour, mealy potato, fishbone dust, powder of pork, bagasse, fermentation cotton dregs, rapeseed dregs as fermentation substrate, consolidated using mixed bacterium The fermentation mode of state, mixed bacteria includes lactoenterococcus, lactobacillus acidophilus, Rhodopseudomonas palustris, aspergillus oryzae, acidified milk bar Bacterium, zymotechnique is：It is 40h, substrate thickness for 32 DEG C, fermentation time that ammoniacal liquor addition 1%, inoculum concentration is 1%, fermentation temperature 30cm。

Above-mentioned fermentation substrate is made up of the raw material of following weight ratio：Corn flour 30%-40%, mealy potato 20%-30%, fishbone dust 5%-10%, powder of pork 5%-10%, bagasse 10%-20%, fermentation cotton dregs 5%-10%, rapeseed dregs 5%-10%, each raw material sum is 100%。

Above-mentioned mixed bacteria includes following component according to mass fraction：

4 parts of lactoenterococcus, 1 part of lactobacillus acidophilus, 1 part of Rhodopseudomonas palustris, 4 parts of aspergillus oryzae, lactobacillus fermenti 4.

Above-mentioned mixed bacteria needs the inoculation liquid for preparing 0.3% bacterial classification content using front, and compound method is according to fermentation The content of substrate weighs a certain amount of bacterial classification and is added to containing in corn flour, the warm water solution of glucose, and 32 DEG C of culture 24h are standby With.

Beneficial effects of the present invention

By the way of mixed culture solid state fermentation, zymotechnique is simple, it is easy to implement for one, the present invention.

The two, feed using this formula, fermenting out, nutriment collocation is reasonable, will not be because of subalimentation or excess Growth to fresh water shrimp has adverse effect on.

Three, using the present invention in Mixed Microbes proportioning, it fermentation substrate can be degraded after with the little of absorption easy to digest The forms such as molecule protein, small peptide, nucleic acid are present, and vegetable protein therein can be converted into the mycelian protein of microorganism, while rich Containing various probios and various enzymes, the development of fresh water shrimp immune organ can be effectively promoted and resistance against diseases is improved, while Also the speed of growth of fresh water shrimp can be accelerated.

The four, biological fermentation feed that the present invention is provided, containing substantial amounts of probio, it can directly absorb or degradation water In organic substance or noxious material, improve the water environment of breeding water body.

Specific embodiment

Embodiment 1

Prepare fermentation substrate：Corn flour 30%, mealy potato 30%, fishbone dust 10%, powder of pork 5%, bagasse 10%, fermentation cotton dregs 5%, Rapeseed dregs 10%；

Prepare mixed bacteria：

4 parts of lactoenterococcus, 1 part of lactobacillus acidophilus, 1 part of Rhodopseudomonas palustris, 4 parts of aspergillus oryzae, 4 parts of lactobacillus fermenti.

Embodiment 2

Prepare fermentation substrate：Corn flour 40%, mealy potato 20%, fishbone dust 5%, powder of pork 10%, bagasse 15%, fermentation cotton dregs 5%, Rapeseed dregs 5%；

Prepare mixed bacteria：

Embodiment 3

Prepare fermentation substrate：Corn flour 35%, mealy potato 25%, fishbone dust 10%, powder of pork 10%, bagasse 5%, fermentation cotton dregs 10%th, rapeseed dregs 5%；

Prepare mixed bacteria：

In order to prove the effect of the present invention, it is real that I carries out feeding to fresh water shrimp in certain Freshwater Shrimp Aquiculture field using this feed Test, it is specific as follows：

The Procambius clarkii that experiment is provided using Xuyi lobster limited company.First Procambius clarkii is placed in into the Shui nationality before experiment System stalwartness, the shrimp that energy is strong and appendage is complete is therefrom selected to use shrimp as experiment after temporarily being supported 5 days with basal feed in case again. The a length of 3-6cm of shrimp body, body weight is 3-8g.Experimental water is the running water through abundant aeration, and natural temperature is（25±5）DEG C, PH is 7.2 ± 0.5, and dissolved oxygen is 5.8-7.0mg/L.Experiment is divided into into control group and test group 1, test group 2 and test with shrimp 3 four groups of groups of group, control group continuation is fed with basal feed, and test group 1 is raised using the biological fermentation feed that embodiment 1 is prepared Hello, the biological fermentation feed feeding that test group 2 is prepared using embodiment 2, the biology that test group 3 is prepared using embodiment 3 Fermented feed feeds.

After culture 60d, the Procambius clarkii growing state of control group and each test group is as shown in table 1：

Group	Length（cm)	Body weight（g)	Feedstuff-meat ratio	Survival rate（%）
					Control group	7.04±0.20	10.12±0.55	2.4	95.8
Test group 1	7.70±0.23	12.01±0.51	2.1	98.3
					Test group 2	7.62±0.21	11.98±0.49	2.2	98.0
Test group 3	7.80±0.24	12.11±0.50	2.0	98.9

Table 1

Experiment shows, using the biological fermentation feed of the present invention, can effectively improve the speed of growth and immunity of fresh water shrimp.
