A kind of feed addictive of preventing and treating the domestic animal sand crack
Technical field
The invention belongs to the feed stripped technical field, be specifically related to a kind of feed addictive that can prevent and treat the domestic animal sand crack, solve the problem of domestic animal sand crack.
Background technology
Along with the raising of boar seed selection degree, the pig back fat is more and more thinner, the speed of growth is more and more faster, fertility is more and more higher, build is constantly improved, but has also caused series of problems, and sand crack namely is one of them.Market pig generation cracked feet generally just realized at the middle and late growth stage or before closing on listing, although market pig seldom because sand crack is eliminated, sand crack can make that its speed of growth slows down, feed intake reduces, the Time To Market prolongation, the loss that brings thus can not be underestimated.Rough calculation, if market pig postpones 10 days because cracked feet causes Time To Market, the loss of every pig just can be up to 60~80 yuan.
Sand crack is a global question, and the reason that causes its generation is many-sided, but main cause is owing to the various nutrients shortage causes, such as calcium phosphorus deficiency, manganese deficiency, scarce zinc, scarce vitamin D, scarce biotin etc.And mycotoxin can cause the vitamin incomplete absorption, causes the shortages such as biotin, vitamin D; The biotin addition is inadequate; Trace element zinc absorbs not, the absorption of Calcium in Feed, iron, the too high antagonism zinc of copper, and the too high antagonism zinc of calcium absorbs in the drinking-water that has; Fat adds not in the feed, causes vitamin A or D incomplete absorption, and Calcium and phosphorous absorption is inadequate, the keratinization insufficient strength; Illumination is inadequate, and vitamin D transforms not, affects Calcium and phosphorous absorption etc., and above-mentioned factor all can cause sand crack.In addition, domestic animal kind, feeding environment etc. also can cause the generation of cracked feet.
At present, for the sand crack that nongenetic, non-feeding environment factor cause, the remedial measure of taking is generally: in seasonal frequently-occurring disease early stage, such as autumn and winter handing-over period, add 200~250mg biotin in feed per ton, to prevent sand crack.As falling ill, the biotin addition can increase by 1~1.5 times, to increasing and decreasing according to circumstances more by the end of January.For dry and cracked coffin, smear cod-liver oil every day 1~2 time, the pig that falls ill the simultaneously 0.5kg carrot of feeding every day is added 1% grease in the mixed feed, to curing cracked feet certain booster action is arranged.Sand crack treatment measure in the production: a bag biotin+compound vitamin+ZnSO
4Spice, injection of antibiotics diminishes inflammation simultaneously.Perhaps utilize existing on the market " care of feed precious " series products blindly to replenish biotin (but fact proved that having added the biotin domestic animal still can sand crack) to pig.Above-mentioned measure is more single, is simple additional a certain element, can not fundamentally solve the sand crack problem.
Summary of the invention
The object of the invention is to provide a kind of feed addictive of preventing and treating the domestic animal sand crack, solves the problem of domestic animal (especially boar, market pig) sand crack.
For achieving the above object, the present invention adopts following technical scheme:
A kind of feed addictive of preventing and treating the domestic animal sand crack, it comprises the raw material of following percentage by weight:
Fatty powder 18~21%
Zinc fumarate 6~8%
Biotin 1~3%
Cobastab
20.3~0.5%
Pantothenic acid 0.2~0.3%
Folic acid 0.2~0.3%
Ethoxyquinoline 0.08~0.2%
Carrier 68~72%.
Described fatty powder is feed grade fatty powder (wherein the quality percentage composition of fat is 40,45 or 50%), and described zinc fumarate is the feed grade zinc fumarate, and described biotin is feed grade biotin (the quality percentage composition of biotin is 2%), described Cobastab
2Be the feed grade Cobastab
2(Cobastab
2The quality percentage composition be 80%), described pantothenic acid is feed grade pantothenic acid (the quality percentage composition of pantothenic acid is 90%), described folic acid is feed grade folic acid (the quality percentage composition of folic acid is 95%), described ethoxyquinoline is the feed grade ethoxyquinoline.
Preferably, the quality percentage composition of fat is 50% in the described feed grade fatty powder; The quality percentage composition of zinc is 36% in the described feed grade zinc fumarate, and the quality percentage composition of ethoxyquinoline is 30% in the described feed grade ethoxyquinoline.
Described carrier is preferably zeolite powder and/or litter shell powder.
The preparation method of additive of the present invention: with biotin, folic acid, pantothenic acid, Cobastab
2, ethoxyquinoline and 1/2 carrier mixing get mixture a; Then zinc fumarate and remaining 1/2 carrier mixing are got mixture b; At last fatty powder and mixture a and b are fully mixed, get final product.Annotate: finished product 100% is by 40 orders.
The usage and dosage of additive of the present invention: cooperate the basic diet of domestic animal to use together, addition is 0.2% of basic diet weight, can play the effect of prevention and treatment sand crack.
The function of each component of the present invention:
Fatty powder: provide capacity essential aliphatic acid, the facilitation that linoleic acid is certain to being absorbed with of biotin.
Organic zinc: sow is inadequate to malabsorption or the Zinc in Feed element addition of zinc element, can cause sand crack or side to split.When boar lacks zinc, do not satisfy skin, hoof keratinization process to the needs of zinc, occur typical sand crack symptom yet, especially the breeding season boar, symptom is even more serious.On the market in the commodity pig's mixed feed zinc content be 52.92ppm, suppose every pig feed 3kg of searching for food every day, day taking in a zinc amount is 158.76mg, also just normally needs 53% of zinc amount.Through the test of Jiangsu Agricultural College experimental center, be 163.75ppm by the hair zinc content when boar is normal, only have 130.9ppm when suffering from cracked feet.The zinc that the present invention adds is zinc fumarate, and is higher than the absorption rate of inorganic zinc.
Biotin: being that animal body is kept the necessary low molecule organic matter of normal physiological function, is the indispensable nutriment of animal body.When long-term lacking or famine biotin, because not keeping cuticula intensity and the hardness of hoof, the hoof tips qualitative change is soft, and very easily wearing and tearing can cause the coffin be full of cracks, and hoof transverse fissure and foot pad crack are also hemorrhage, sometimes have the symptoms such as rear foot spasm, depilation and inflammation.According to investigations, the pig on many national pig farms has the situation of egg-white injury, the biotin that contains effective value in its feed is too low, cause that the hoof tips qualitative change is soft, easy to wear, it is coarse to add pigsty floor, thereby cause cracked feet, breach then can occur and infect, occur when serious walking lamely, particularly intensive airtight feed lacks motion and this disease of the easier generation of solar radiation.Biotin has certain effect to cuticula intensity and the hardness of keeping hoof, and is relevant with limb hoof tips materialization and hoof integrality.Its participates in carbohydrate, lipid, protein and the nucleic acid metabolism of body, and participates in the metabolic processes such as other nutriments such as Methyl transporters reaction, also with the function of lysozyme activation and sebaceous glands, and Cobastab
6, folic acid, pantothenic acid metabolism closely related.Dry weather, temperature shakiness, sow is for the variation that conforms, and the body surface capillary shrinks, because the biotin metabolism occurs unusually, causes normal lipid material to be secreted and reduces, and it is thin tender that coffin becomes.Fat in the daily ration, folic acid, pantothenic acid, Cobastab
12Cobastab
6Deng all closely related with absorption and the metabolism of biotin.
Cobastab
2: have the growth of promotion and cytothesis; Promote the normal growths such as skin, nail, hair; The function of protection skin follicle mucous membrane and sebaceous glands; Also be protein, sugar, fatty acid metabolism and energy utilization and the necessary material of composition, can protect the health of skin.Cobastab in the body
2Storage be extremely limited, therefore need in the feed of every day, provide.Cobastab
2Easily by photo damage, in alkaline solution heating also easily destroyed be the main cause that causes its loss.
Pantothenic acid: play an important role in a lot of metabolic processes, it is essential for synthetic, the amino acid whose oxidative degradation of synthetic and degraded, the membrane phospholipid (comprising sphingolipid) of aliphatic acid.The major physiological activity form of pantothenic acid is coacetylase and acyl carrier protein, and their metabolic function is as acetyl group or fatty acyl group carrier.Pantothenic acid helps to form cell in vivo, is fat and sugar class indispensable material when being transformed into energy.In addition, can also resist stress, anti-infective, prevent some antibiotic toxicity.
Folic acid: be a kind of water-soluble B family vitamin, all most important to the multiple physical body metabolic processes, people's somagenic need with its erythroblast, norepinephrine and salad holder peaceful (neural chemical composition) in next life.Show that according to contemporary Chinese medical journal data people's pregnancy period Supplement of folic acid can prevent neonate's actinal surface to split.Use folic acid can promote this mechanism of skin health, the present invention adds this vitamin to promote the product effect.
Beneficial effect of the present invention:
Additive of the present invention is rich in the required various nutrients of domestic animal (such as grease, vitamin and organic trace element etc.), and reasonable mixture ratio science, provide the good growth such as domestic animal skin, cuticula, hair follicle, sebaceous glands the nutritive and health protection components required with Function, can effectively prevent and treat the domestic animal sand crack, High-efficient Production for boar provides basic guarantee, the stealthy economic loss of effectively avoiding market pig to cause because of sand crack.
