Description
Technical field
The present invention relates to field of feed additive technology, and in particular to a kind of feed addictive of prevention chicken sudden death.
Background technology
Rare bird cultivation sudden death syndrome, disease is jumped also known as turning over, be rather troubling chronic disease in modern rare bird aquaculture it
One.This disease is often betided in the Broiler chicks of 3 ~ 35 ages in days.It is characterized in that outward appearance is larger, fleshiness chicken is mostly occurred, it is sick
Preceding to be taken action out of control suddenly without obvious sign, scream, front and rear tumble, dipteron is acutely agitated, muscle cramp, and then neck leg is stretched, and is carried on the back
Portion lands and dead.Cut open inspection result is basically identical：Cardiac enlargement, pericardial fluid increases；Lung is dark red, oedema；Liver increase, it is pale,
It is frangible；Kidney bleaches；Splenomegaly；Bursa of farbricius enlargement；Ectopia cloacae etc..The average sick rate of sudden death syndrome is 1% ~ 3%, public fowl life
Sick rate is apparently higher than female bird.Some expert investigations show, the disease be after Marek's disease and chronic respiratory after being ill, harm extensively
The topmost new disease of poultry husbandry.Although the death rate of syndrome of dying suddenly is relatively low, it account for very in general mortality rate
Big proportion, so the preventing and treating to the disease is significant.
The content of the invention
It is an object of the invention to provide a kind of feed addictive for preventing chicken to die suddenly.
The technical solution adopted by the present invention is,
A kind of feed addictive for preventing chicken to die suddenly, the additive is made up with mole cricket of raw material, when specifically making,
（1）Mole cricket and water are pressed 1:10 part by weight mixed grinding screened stock, particle sice in serosity adds after 90-100 mesh, slurries sterilizing
Heat adjusts its pH value to 8.3-8.5 to 60-62 DEG C, adds alkali protease to digest 5-6 hours by the part by weight of 2%-3%；
（2）High temperature is gone out after enzyme, is cooled to 33-35 DEG C, adjusts slurries pH to 2.2-2.5, and acid is added by the part by weight of 1%-1.8%
Property protease hydrolyzed 2-3 hours；
（3）High temperature is gone out after enzyme, is cooled to 10-13 DEG C, adjusts slurries pH to 5.5-6, and low temperature egg is added by the part by weight of 5%-7%
White enzyme is digested 14-15 hours；
（4）The enzymolysis liquid that the enzyme that goes out is obtained, is then centrifuged 6-8 minutes with 5000-5500 revs/min of rotating speed, discards precipitation, is obtained
Supernatant；
（5）Supernatant obtains preventing the feed addictive of chicken sudden death through vacuum, low temperature, spray drying.
Beneficial effect of the present invention is that the present invention makes the feed addictive for obtaining prevention and treatment chicken sudden death by former material of mole cricket
Effect is fabulous, and more than 99.6%, cure rate has no drug resistance prevention effective percentage more than 83.8%, the mole cricket former material valency for being used
Lattice are cheap, easily materials, and process is not used chemical addition agent or extractant, the finished product safety non-toxic for obtaining.

Below in conjunction with specific treatment and prevention example, the present invention is further described；
Wherein prevention example is subjects with the same kind chick of firm hatching, totally 200, is randomly divided into experimental group and blank group
2 groups, every group 100, test period is 1 year, and during experiment, two groups of feeding environments, feeding feed stuff, management methods are identical,
Two groups of live box feeding feed stuffs are conventional feed, and without prevention chicken sudden death composition, experimental group, will be by embodiment 1 during testing
The additive that making is obtained is made an addition in daily grain of chicken, wherein, addition is that 2 ‰, 3-6 monthly age additions are before the monthly age of preceding chicken 3
Addition is 2% after 8 ‰, 6 monthly ages；
After off-test, chicken sudden death incidence, as a result see the table below 1 during statistics each group experiment：
| Group | Chicken sudden death incidence（%） |
| Blank group | 38% |
| Experimental group | 0% |
During above-mentioned experiment, to the additive that the ratio addition embodiment 1 in the daily grain of chicken for sudden death symptom occur in 5% is obtained,
The ill poultry of feeding, is used in conjunction 3-5 days, statistics case fatality rate, cure rate；The results are shown in Table 2：
| Group | Case fatality rate（%） | Cure rate（%） |
| Diseased chicken | 3 | 35 |
As shown in Table 1, the additive for being obtained to the addition present invention in daily grain of chicken can significantly reduce chicken sudden death incidence rate, have preferably
Preventive effect, to occurring adding the additive that the present invention is obtained in symptom diseased chicken daily ration, have preferably effect to treatment chicken sudden death
Really, diseased chicken The dead quantity is significantly reduced.
