Description
Technical field
The present invention relates to a kind of feed addictive, particularly relate to a kind of feed addictive of the raising lactation performance of lactating sows based on the seed of cowherb.
Background technology
Breast milk is that piglet is nascent to the source of the main nutrient matter between weaning period, and the quality and quantity of breast milk has determined the survival rate and the speed of growth of piglet.The low milking capacity of sow can directly cause piglet nutritional deficiency, slow, the death rate of growth to increase, and influence the weaned piglet body weight, and the aggravation stress of baby pigs caused ablaction also influences the subsequent growth growth.Therefore, the elementary object between sows in lactation is to guarantee the enough nutrition of sow absorption, and the milk that secretion is sufficient keeps suitable body condition, and sow can normally be oestrused behind weaned piglet and ovulation, enters the next one breeding cycle.Have data to show, compare with foreign outstanding sow milk performance, the lactation potentiality of domestic most milking sows are only brought into play about seventy percent, thereby room for promotion is very big.Domestic many scholars have done a large amount of research to this, as increasing the addition of energy, proteins,vitamins,and minerals in agent of feed for nursing sow, but produce little effect.That have even in sow feed, add the feed addictives of a large amount of antibiotic and so on, not only can not improve the milk performance of sow, but also animal is developed immunity to drugs, have a strong impact on reproductive performance of sow and the health of piglet.For this reason, people urgently wish to develop a kind of milk performance that had both improved milking sow, noresidue again, the feed addictive that has no side effect.
Chinese herbal medicine is the rarity of motherland's medical science, and China people have the history of long use Chinese herbal medicine.Chinese herb feed additive has functions such as promoting growth, prevent disease, raising lactation, use the back to the animals and animal product noresidue, have no side effect, be difficult for developing immunity to drugs.Because the use of Chinese herbal medicine also rests on the basis of experience and conventional formulation, add that traditional research method and manufacture craft fall behind, the Chinese herbal medicine of feasible China is not well utilized and is developed, especially in feed additive industry, the utilization of Chinese herbal medicine is very not extensive, and effect also is under suspicion.Mainly there is following several big problem in restriction Chinese herbal feed additive large-scale application: (1) adding proportion height: because conventional method adopts common pulverizing, drug effect in the plant can not be utilized by the animal fast Absorption, therefore everybody adopts high addition more, generally need add 0.5%～5% to does not wait, cause cost to raise, and high addition causes the feed palatability poor, and animal produces few food or food refusal behavior; (2) drug effect is slow and waste is serious: Chinese medicine plays a role by group effect, does not reach the Western medicine level on taking stopgap measures fully, because plant directly enters in the intestines and stomach, the active ingredient in the plant could finally be absorbed by animal after by plant cell wall.Because food has only certain stop effect in intestines and stomach, some active ingredient fails in time to be absorbed by animal, just along with chyme excretes, makes drug effect can not get embodying; (3) process technology is improper: the someone proposes to adopt advanced microwave leaching technology, Chinese herbal medicine effective ingredients is improved significantly, but different pharmaceutical leach extraction method difference, the solvent difference, technical difficulty is very big, the cost of investment height, and have pollution problems, the extract unit cost that its production obtains is extremely high, has limited popularization.
We are verified in research several years ago, adopt suitable cell grade micro mist broken, and effect is poor unlike extracting effect, not only reduce addition but also reduce cost, suitable applying.
Broken being meant with the biological cell broken wall of cell grade micro mist is the comminution process of purpose, and it is not purpose with the smashing fineness, but pursues the sporoderm-broken rate of cell.Broken by the cell grade micro mist, the medium particle diameter of former green material can be brought up to more than 300 orders from 40～80 orders of traditional handicraft, for general medicinal material, the breaking-wall cell rate under this fineness condition is greater than 95%.Cell intracellular active ingredient behind broken wall fully comes out, the rate of release and the burst size of medicine can significantly improve.The medicinal material particle is after the cell grade micro mist is broken, and microscopically is observed only has the minute quantity intact cell to exist.The cell grade micro mist is broken to mainly contain following advantage aborning: (1) increases the drug absorption rate, improves the Chinese traditional medicine biology utilization rate.The main pharmacodynamics composition of Chinese medicine is distributed in the cell and cytoplasm usually, and based in the cell.Active ingredient comes out in its cell behind the breaking-wall cell, and drug effect increases substantially, and onset speed is fast; (2) help the retains biological activity composition, improve drug effect.In the broken process of cell grade micro mist, can not produce superheating phenomenon through control, or under low-temperature condition, carry out, and pulverizing speed is fast, helps keeping the bioactive ingredients and the various nutritional labeling of non-refractory, thereby improve drug effect; (3) conservation is convenient to use.Chinese medicine is after the cell grade micro mist is broken, and available smaller dose obtains the curative effect of former prescription (decoction).General medicine, after the cell grade micro mist is broken, no longer pass through lixiviate, etc. processing, reduced loss of active ingredients in the production link, maximally utilised raw material, and, be convenient to take because the increase of fineness can improve mouthfeel.On the other hand, be in totally-enclosed dustless system, to carry out because of the cell grade micro mist is broken, can effectively avoid outside contamination, the content of microorganisms of product and dust are controlled.Predictably, the broken technology of Chinese medicine cell grade micro mist will provide preferable approach for the Chinese medicine utilization.
From the modern nutriology theory analysis, the contained alkaloid of Chinese herbal feed additive, polysaccharide, glucoside, volatile fatty acid, organic acid etc. all are bioactivators, to improving mammiferous milk performance good action are arranged.Some composition in the Chinese herb feed additive and mammogenesis, galactin synthetic and secrete closely related, as promote prolactin, cortex hormone of aadrenaline secretion etc., the Chinese herbal medicine that quickens galactosis is by improving body courier's material (cAMP and cGMP) level, regulate the metabolic activity of mammary glandular cell, promote the growth of the synthetic and mammary gland of mammary gland anabolism, milk composition, realize increasing the effect of breast.The seed of cowherb has activating blood to promote menstruation, the effect of lactogenesis detumescence, can treat agalactia, through close, disease such as dysmenorrhoea, acute mastitis swell and ache.The cell culture experiments confirmation, the seed of cowherb, the Radix Astragali can promote mammary glandular cell to absorb the outer free amino acid of born of the same parents, make the synthetic increase of mammary glandular cell albumen by reinventing mammary glandular cell inside is Ultrastructural.Current awareness search work station (Z09) looks into new confirmation through the Ministry of Education, is that the feed addictive of the raising lactation performance of lactating sows of master side does not appear in the newspapers with the seed of cowherb.
Summary of the invention
Technical problem to be solved by this invention is: overcome the deficiencies in the prior art, a kind of feed addictive of improving lactation performance of lactating sows and preparation method thereof that is used to is provided.
The present invention solves the technical scheme that its technical problem takes: this feed addictive that is used to improve lactation performance of lactating sows is composed of the following components, and the total weight parts of described each component is 100 parts, wherein,
50～60 parts of the seeds of cowherb
5～8 parts of dandelions
8～10 parts of rhizoma atractylodis
5～8 parts of akebis
5 parts of the Radixs Astragali
5 parts in Radix Glycyrrhizae
