Pig farm often should inject only to the pig vaccinal, medicaments, occasionally, we can discover pig inject, do not have due effect however; This among them reason, it is the choice because of medicaments commonly undeserved or the dosage of inject is undeserved wait, the means method that of course still a main factor injects namely is undeserved.
The inject method with commonly used swinery includes inject of intramuscular injection, hypodermic, vein and celiac inject.
One, intramuscular injection
Point to will vaccinal inject within muscle. Notice syringe needle wants when inject enough long, in order to assure vaccine really in infuse muscle, intramuscular injection place is binaural hind sticks enclothed area.
① , general situation, no matter be vaccine or medicaments,best inject is in cervical (the position sees a picture 1, 2) , because of coxal muscle " hard " , cause a pig easily should stimulate, muscle stretchs tight closely, bring difficulty to inject. This position masters hind leg inside not easily also, not easy Baoding. Cervical skin is loose, muscle is rich, the benefit absorption at medicaments, capture ear ministry easy Baoding, so best inject is in cervical.
② , number one is the diameter of aperture of pressing with a finger, the diameter is bigger, the medicaments that the inject inside unit time enters is more. What give out below is referenced data, specific applying, deepness of dosage of property of the size that the choice of syringe needle wants to consider a pig, medicaments, inject, inject.
When ③ , inject perpendicular at body skin skin receives an injection, the attention injects from the back of the pig, make sure the pig is in only as far as possible narrow space.
Inject is undeserved, if pursue,meet, occurrence pus bubble
2, hypodermic
subcutaneous tissue of medical fluid infuse, pig farm is commonly used is to give swinery to hit drive bug needle, normally we give kind of swinery the syringe needle that inject grows with 20-25mm, perpendicular go into the needle, the syringe needle that uses normal length is spent with respect to 40-45 into the needle, particular operation pursues as follows:
3, vein injects
Vein injects: Vein inject is medical fluid direct inject arrives inside blood-vessel, make medical fluid produces the technology of a kind of cure of the effect quickly. Basically use at rescue danger to weigh ill pig, choose ministry of hard of hearing commonly, ear vena cava. When online · expert suggests to do vein to inject, · pig farm uses ear of alcohol tampon inunction first rear ear vena cava, make vein angry piece, assistant coerces vein of ear radical ministry to make hemal beat rises with finger.
4, celiac inject
Celiac inject is medical fluid inject arrives inside abdominal cavity, achieve remedial goal thereby. Piggy often uses this kind of method. When online · expert suggests to inject, · pig farm shoulds not be too deep or slant at ahead, lest injure splanchnic organ. Also cannot too slant at rear, lest injure the bladder of fluid of Gu full make water.
Multi-purpose at young pig. Because abdominal cavity can accommodate many medicine fluid to have relatively absorb ability, reason but infuse is larger medical fluid. But must be not to have pungent medical fluid, weather chill is noted again measure into medical fluid relatively a long time, need to add medical juice lukewarm to ～ of 38 ℃ 39 ℃ . If bigger pig, send ear ministry cyanosis due to illness, when cannot seeing clear blood vessel, also can make celiac injection.
Young pig can mention Baoding of two hind legs, bigger pig can make its lie on his back, after showing tall before small gesture. Before noting, shake first pig hind legs, make bowel is in charge of forward ministry to move. Next poodle disinfection.
Inject place arranges 37.5px place in the side outside penult tit. Syringe needle had better choose long and thin pinhead, the dot removeds the skin to a side first before inject, show pinhead of perpendicular penetrate into with the skin again, the pinhole on such skins and abdominal muscle. The pinhole on peritonaeum is absent to go up point-blank, can prevent celiac infection. After syringe needle penetrate into is celiac, return the heart that take an injection, look to whether have alvine content thing, if can be not noted,enter medical fluid, speed shoulds not be too fast, a pinhead is dialed after noting, disinfection.
Different kind gives medical characteristic
Intramuscular injection: Place of advantage as above says, absorb fast, ache is light, medical effect rapid, dosage accurate, action is credible, can arise local reach directional action, but defect is to may cause muscle spasm.
Hypodermic: Achieve medical effect quickly, cannot or when unfavorable classics profess to convinced gives drug, can use. Be digested easily inside gastric bowel path like insulin profess to convinced enzymatic destroy, lose action, and hypodermic is absorbed quickly, solution, excitant to Yi Rong small perhaps do not have excitant medicaments and vaccine, can make subcutaneous injection. Defect is workload inject dose is big, large, stimulating wait.
Vein injects: The effect since vein inject is the fastest, biology availability is highest also, it is very difficult to hit vein to pig pig at ordinary times, use at rescue commonly sick into death pig.
Abdominal cavity injects: Peritoneal less than, its draw rate faster (2 hours of or so) . When the pig only lesser and when searching ear vein hard, or day cold skin vasomotor or the pig is in anaemic and angular circumstance when blood-vessel is not apparent, die with anticreep water through celiac inject fluid infusion, because issue above of dysentery dehydrate 1/3 to have life risk namely, celiac inject is familiar pattern giving drug, it is especially when anaesthesia, and the operation is convenient. Defect is any medicaments applicable, some meetings affect the effect time of medicaments, the influence is absorbed.
Medicaments of different approach giving drug draws rate different also, general vein injects > inspiratory to medicine > celiac inject > intramuscular injection > hypodermic > profess to convinced gives drug > rectum gives drug. Because all sorts of means giving drug have actor drawback each, the manage of medicaments changes property and biologic characteristic also the difference is very big, the proposal is specific the way giving drug when using drug, still require specific condition concrete analysis.
