Description
Technical field
The present invention relates to a kind of animal feed additive, more particularly, to raising Funiu White Goat speed of weight increment and immunity
Feed addictive and its preparation method.
Background technology
Funiu White Goat is Henan Province's Local Excellent kind, is mainly distributed on the Funiu Shan Mountain in Western Henan Province and the west and south
Area.Funiu White Goat has that meat production is good, dressing percentage is high, reproductive performance good, resistance to thick feeding, premunition are strong, suitable mountain region is herded
The advantages of.
Some diseases are frequently encountered in the feeding process of Funiu White Goat, treatment disease not in time can cause serious
Loss.But the diagnosis of the disease in actual operation needs to overcome more suffering, could correctly accomplish, therefore in reality
The prophylactic discovery of operation, improve Funiu White Goat resistance against diseases seem of crucial importance.Traditional method is using anti-
Raw element class medicine.But because the generation of drug resistance, antibiotic are accumulated in vivo, the harm to chicken health is had resulted in, and
Excessive antibiotic is excreted to the environmental pollution caused in environment, and then influence is will also result on human health, thus both at home and abroad
Begin one's study biological control or bionomic control, green feed additive is developed, in the hope of solving the above problems.
The Chinese patent of application number 201210486329.4 discloses a kind of raising Funiu White Goat speed of weight increment and is immunized
The feed addictive and its preparation method of power, improve the feed addictive and its preparation method of Funiu White Goat speed of weight increment and immunity, institute
The feed addictive stated is made up of the Radix Astragali, dried orange peel, malt, the bark of official magnolia, the dried immature fruit of citron orange, rhizoma atractylodis, the fruit of glossy privet, Poria cocos and zeolite, and each component is accounted for
The mass percent of feed addictive total amount is:Radix Astragali 28%-52%, dried orange peel 20%-30%, malt 8%-12%, bark of official magnolia 9%-11%, trifoliate orange
Real 4%-6%, rhizoma atractylodis 4%-6%, fruit of glossy privet 1%-3%, Poria cocos 1%-2%, zeolite 1%-2%.Chinese herb feed additive of the invention can show
Production performance, the immunity of organisms for improving Funiu White Goat are write, its feedstuff-meat ratio is reduced;And the immune of Funiu White Goat can be promoted
Competent cell activation, so as to improve the immunologic function of body.
There is the effect on driving birds is not good of Chinese medicine in the technology, the raw material for using are relatively more, the more expensive problem of cost of material.
The content of the invention
The invention aims to provide, using effect is good, improve the feed of Funiu White Goat speed of weight increment and immunity adds
Plus agent and its preparation method.
Solving the technical scheme of its problem is:
Improve the feed addictive of Funiu White Goat speed of weight increment and immunity, including following percentage by weight composition:

(0.25 μm of filter membrane diameter)Tromethamine, pullulan, sodium selenite solution add fermentation medium in, while need addition
L-Methionine;
3)Fermentation tank culture:Full-automatic 5L stirred-tank fermenters(BIOTECH-5BGZ, it is public that emerging biological plant engineering finite is protected in Shanghai
Department)Middle dress fermentation medium 3L, inoculum concentration 10%(v/v), speed of agitator 350r/min, 23-27 DEG C of temperature, the L/ of throughput 3.0
Min, incubation time 25-30h.Determine pH.
Preferably, step 1):Culture 20h, 30 DEG C of cultivation temperature, shaking speed 200r/min;
Preferably, step 2):Shake flask fermentation culture, 27 DEG C of temperature, shaking speed 200r/min;
Preferably, step 2):L-Methionine is added in 0h, and addition concentration is 10 m mol/L;
Preferably, step 3):Dress fermentation medium 3L, inoculum concentration 10%(v/v), speed of agitator 350r/min, 27 DEG C of temperature, lead to
The L/min of tolerance 3.0;
Preferably, step 3):PH is detected in place using plum Teller electrode, by the mol/LH of auto-feeding 32SO4Or 3 mol/
LNaOH solution is adjusted maintaining pH to change within ± 0.02.
Beneficial effects of the present invention:The feed addictive for improving Funiu White Goat speed of weight increment and immunity of the invention and
Its preparation method, by adding Se-enriched yeast, in Se-enriched yeast and tromethamine, pullulan, sodium selenite intermixture group whole blood
The vigor of GSH-Px and the content of serum selenium are significantly increased, and particularly Se-enriched yeast has biology higher to ruminant
Utilization rate, therefore selenium content is few in excreta, is conducive to environmental protection.Tromethamine and pullulan also have enhancing anti-after combining
The effect of sick ability.Selenium has humidification to animal cell immunity function, can improve the conversion of periphery blood lymphocyte simultaneously
Ability, improves T cell quantity in lymphocyte, so as to strengthen the premunition of body, can improve the antioxidation of body, reduces
The destruction of free radical and MDA to cell membrane integrity, so as to improve the immunity and resistance against diseases of body.
