Swine Artificial Insemination Procedures

As the swine industry scale and intensive level of continuous improvement, breeding sows has a direct impact on the level of the financial advantages of farmers. To raise the level of sow breeding one of the most direct and effective way is usually to use Artificial Insemination. Artificial insemination technologies not merely can greatly improve the conception price of sows to accelerate the pace of improvement of pig breeds, and market the improvement of pig production levels, but also substantially reduce the amount of boars in the breeding and lessen fees. Artificial insemination of pigs in Incubator China inside the early 50s from the 20th century a modest quantity of institutions of greater understanding, scientific analysis units to test the late 70s much more broadly employed inside the production, and accomplished great impact. But our existing artificial insemination price of about 30% in the created countries and 60% to 85% possess a gap, as a result, also vigorously promoted. The procedure of artificial insemination possess the following methods:

Ready just before semen collection semen area cleaning and disinfecting; regulation Laboratory Thermostatic Bath at space temperature to 25 . To set precise Cup, Holes Glass Tube Air Dryer rod, thermometer, gauze, latex gloves and other equipment placed at 40 incubator preheated (except in summer time); microscope regulate the focal length, maintaining the temperature boxes microscopy 35 ~ 37 , containing Holes Glass Tube Air Dryer film and into the microscope coverslip box preheat; prepared warm Baking Water Bath around 25 .

Boar semen collection wrapper around the extended hair reduce, circumcised crowding, the inner item in urine, utilizing a damp cloth dipped in potassium permanganate Baking Water Bath back one way by the circumcision mouth clean. Semen release are normally easy to make use of the hand technique. The donor members must put on latex gloves, the boar semen collected in collection cup fine, fine cup set with two to 4 layer gauze hooded filtration at space temperature with low thermal insulation needs to set the cup, then speedily test room inspection, diluted and can be stored.

Clear liquid Top quality Inspection Visual inspection semen standard gray or white colour, the higher the concentration the more the colour white; typical smell slightly fishy smell, or smell; usually weakly alkaline or neutral. Determination of sperm vitality

verify is always to make certain that sows impregnated an essential technology. Particular methods of operation are: semen drops within the 38 continuous temperature of the Holes Glass Tube Air Dryer slide, a ten point method to score, fresh semen survival rate greater than 0.6, storage of semen survival rate greater than 0.four. Morphological examination of sperm tails

, decapitation, a protoplast, the first large, double-headed, two-tailed, Orio, and so on. are deemed abnormal sperm. The rate of boar sperm fine not greater than 18%, greater than 20% of not appropriate for Insemination.

Inspection is usually to establish the concentration of checking the concentration of sperm dilution on the crucial basis of visual observation by means of the microscope approach, the semen might be divided into dense, medium and sparse three levels. Additionally, the board may also be obtained by blood count, sperm density gauge correct calculation of sperm density. One of the most commonly used artificial insemination sperm density of 0.five million / ml, insemination of 60 to 80 ml, to ensure successful sperm 3000000000 ~ 4000000000.

Semen dilution, repackaging, and save the pig semen dilution formula There are numerous, according to their effects, preservation methods, and economical decision to make a decision which. The formula frequently utilised is: glucose 5 to six grams of sodium citrate 0.three to 0.5 grams of EDTA or EDTA 0.1 g, enhanced to 100 ml with distilled Baking Water Bath, the scale of pig farms normally by 1000 ml volume of preparation. OK properly after dilution, the corresponding diluent into the semen along Beibi slow, slow rock edge chamfer; diluted semen in accordance using the specifications of separate packaging, the sperm will be kept at area temperature 1 to two hours slow release after 17 temperature into the refrigerator. Estrus in sows

Insemination fit accurately the quality of sperm transport towards the cervix, the pregnancy price is higher to make sure an essential hyperlink in sows. Insemination of particular techniques of operation are: Get rid of the stored semen, Sperm viability inspection, following passing the slow warming to 37 for insemination. Insemination must sow vagina prior to a clean wipe using a towel, when the very first upward into the vas deferens, in accordance with anticlockwise cervical arrival in sows.

In brief, the proper use of artificial insemination technology can significantly enhance the sow conception rate, enhance the good quality of pigs to lessen the spread of disease, decrease production charges and the majority of farmers to attain higher financial advantages, is worth advertising.
