Abstract

A kind of control growth period of animal fur and the ontogenetic method of promotion.Contain the silicon capsule of melatonin at the DAZHUI acupoint subdermal implantation of fur-bearing animals such as mink, the 0.7-1.2mg/ kilogram, body weight makes long-acting, slow release go out melatonin, and the bark fetching time that can make animal is in advance and promote the ontogeny of animal.A kind of special Luer's syringe makes operation easy, easily row for heeling-in medicine usefulness.

Description

The method and the specific purpose tool of control growth period of animal fur

The present invention is a kind of method with medicine control growth period of animal fur and promotion growth.

The fur of some precious fur-bearing animals such as mink etc. has very high economic worth.Mink had twice moult spring and autumn in 1 year, and the winter staple length just can be slaughtered bark fetching after becoming.This seasonality of mink and some animals is moulted and is subjected to the adjusting of periodicity of illumination.The winter hair is grown in advance in order to induce, maturation, thereby makes the bark fetching time in advance, reduces feed cost and administrative expenses, can control growth period of animal fur with manual light control's method.Xiao Yongjun etc. have reported with constant short-day and the method that shortens sunshine gradually and have made mink winter hair maturation time (zoology magazine in advance, 24(4): 26-30,1989), but this method is because animal population is big, control is difficult, need to build photocontrol room and some auxiliary devices, expensive big, the popularization of this method is restricted.Peptide hormone melatonin (melatonin) can produce the effect that is equivalent to regular minimizing illumination in animal body, can make animal in long photoperiodic midsummer, on physiology, promptly enter short photoperiodic autumn, the summer hair is come off in advance, bring out the growth ahead of time of winter hair, make the bark fetching time in advance.Report can stimulate woolen growth of goat and the woolen growth cycle of control goat with the method for melatonin control goat wool growth in the European patent EP-0241272, increases the output of the high high-quality cashmere (Cashmere) of commodity value.

The object of the present invention is to provide a kind of melatonin can bring out the short-cut method that precious fur-bearing animal winter hair is grown in advance and promoted to grow with trace.Method is simple for this, need not anaesthetize, and the heeling-in position of melatonin microencapsulation is reasonable, and postoperative is unlikely to be bitten by animal self.Another object of the present invention provides a kind of instrument that supplies the heeling-in medicine to use.

Embodiment of the present invention are that melatonin is contained in the little silicon capsule, and heeling-in is at subcutaneous particular acupoint, and the heeling-in of saying so more specifically is in DAZHUI acupoint, make long-acting, slow release go out melatonin with the control growth period of animal fur with promote animal growth.Used silica gel tube internal diameter is 2.4mm, and it is cut into the long short tube of about 1.5cm, uses 70% alcohol flushing, sterilization, dry for standby.With binding agent with an end sealing.Melatonin (white powder goods) is dissolved in 30% ethanol, makes every 50ul contain the 0.50-0.85mg melatonin, melatonin solution is added silica gel tube, decompressing and extracting under the room temperature with sample injector.The capsular other end can seal or open-ended.Available one little square table is as operating-table, skin place iodine disinfection in mink DAZHUI acupoint (on first vertebrae), cut an osculum (about 0.5 centimeter), take out special sleeve pipe syringe (as accompanying drawing), to contain the microencapsulation of melatonin by the fenestella (1) of the syringe sleeve pipe syringe cavity (2) of packing into, it is subcutaneous that sleeve pipe syringe needle (3) is inserted DAZHUI acupoint by otch, advance the real core of syringe to advance post (4), capsule is imbedded definite position, take out the sleeve pipe syringe, with iodine tincture cotton balls sterilization wound, need not sew up, operation finishes.The amount of the ermine heeling-in melatonin of every heavily about 700 grams is 0.50-0.85mg, and promptly per kilogram of body weight is buried medicine 0.7-1.2mg.

The sleeve pipe syringe is by a metallic sheath tube chamber (2), and the real core of rustless steel advances post (4), and syringe needle (3) and propeller spring (5) are formed.The thick 1cm of casing cavity, internal diameter 0.4cm, long 4.5cm, pars intermedia has a wicket (1) on telescopic chamber, long 2cm, wide 0.5cm, contain Drug Capsule from then on window put into syringe cavity.At the tubulose syringe needle (3) of telescopic front end spreading 2cm, telescopic trailing edge connects a spring (5), supports solid propelling post.

This method is simple to operate, determines the subcutaneous of acupuncture point because special syringe can be squeezed into capsule, and otch is little, capsule can not overflow, and has removed the drug anesthesia of general operation usefulness from, Baoding, shave operations such as hair, stitching, the operation of every ermine can be finished in 1-2 minute.Once bury medicine, slow release, long-acting, the medication trace, with low cost.It is reasonable to bury the medicine position, and animal itself can not touch, can avoid scratching or biting, but nearly all position of mink health all self touch, but big vertebra acupuncture point place can not touch.It is good to bury medicine animal appetite, does not have any untoward reaction.Can make mink summer hair shift to an earlier date 1-1.5 month with this method and come off, bring out winter hair growth, the fur period of maturation can shorten 1-1.5 month, and the bark fetching time is greatly shifted to an earlier date, and saves feedstuff, labour, administration fee etc.This method promotes ontogenetic effect in addition, and the body that is tried ermine is long, and body weight and pelage quality all are better than contrasting the ermine group.The fur that is tried ermine all is first class basically, and body is long than the long 3-5 centimetre of the ermine group mean of raising under similarity condition.

This method is to some other fur-bearing animal, and as Vulpes, Nyctereutes procyonoides, Felis lynx linnaeueus., down producing goat etc. also are suitable for.

Embodiment

Being tried ermine is 650 public ermines, in late July heeling-in melatonin capsule, and every heavily about 700 grams of ermine, the amount 0.85mg of heeling-in melatonin.To contain Drug Capsule from pack into the sleeve pipe of syringe of the fenestella of special Luer's syringe, cut about 0.5 centimeter long osculum at the place, big vertebra acupuncture point that is tried ermine, the syringe needle of syringe is subcutaneous by little otch insertion, and the real core of pushing syringe advances post that capsule is squeezed into, and operation finishes.

Good from the heeling-in capsule to slaughtering bark fetching animal subject appetite, have no adverse reaction.

Early September is tried ermine and begins the summer hair and come off, winter hair growth, and contrast ermine group begins the summer hair late October and comes off winter hair growth.

Get and tried 45 of ermines to survey body when performing the operation July 29 long, average 37.5cm, JIUYUE measurement on the 11st, the long 42.0cm of average body, balanced growth 4.5cm therebetween.The contrast ermine is got 30 tests, increases to 40.7cm by 39.9cm respectively in the above-mentioned identical time, and average body length increases 0.8cm.

Tried ermine early November and slaughter bark fetching, 650 furs are first class, and size reaches 130% 195,260 of 120% size, 195 of 110% size.The government purchase standard is 59 centimeters, size 100%.

Contrast ermine group early December bark fetching, in 165 public ermines, not the having of 130% size, 40 of the first class skins of 120% size, 80 of the first class skins of 110% size, 15 of the first class skins of 100% size, other has 30 sizes below 100%, promptly less than 59 centimeters.
