Swine Artificial Insemination Procedures




As the swine industry scale and intensive degree of continuous improvement, breeding sows features a direct influence around the level of the economic benefits of farmers. To raise the level of sow breeding one of the most direct and effective way is to use Artificial Insemination. Artificial insemination technology not only can significantly enhance the conception price of sows to accelerate the pace of improvement of pig breeds, and promote the improvement of pig production levels, but in addition drastically reduce the number of boars inside the breeding and minimize charges. Artificial insemination of pigs in Incubator China inside the early 50s from the 20th century a little quantity of institutions of higher understanding, scientific research units to test the late 70s far more widely utilized within the production, and accomplished very good impact. But our existing artificial insemination rate of about 30% in the created countries and 60% to 85% possess a gap, consequently, also vigorously promoted. The procedure of artificial insemination have the following methods:
Prepared prior to semen collection semen space cleaning and disinfecting; regulation Laboratory Thermostatic Bath at room temperature to 25 . To set precise Cup, Holes Glass Tube Air Dryer rod, thermometer, gauze, latex gloves along with 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; ready warm Baking Water Bath about 25 .
Boar semen collection wrapper around the extended hair cut, circumcised crowding, the inner item in urine, making use of a damp cloth dipped in potassium permanganate Baking Water Bath back 1 way by the circumcision mouth clean. Semen release are generally basic to use the hand approach. The donor members must put on latex gloves, the boar semen collected in collection cup fine, fine cup set with 2 to 4 layer gauze hooded filtration at space temperature with low thermal insulation wants to set the cup, then swiftly test room inspection, diluted and can be stored.
Clear liquid High quality Inspection Visual inspection semen normal gray or white colour, the larger the concentration the a lot more the colour white; normal smell slightly fishy smell, or smell; usually weakly alkaline or neutral. Determination of sperm vitality
verify would be to make certain that sows impregnated a crucial technology. Distinct methods of operation are: semen drops inside the 38 continual temperature on the Holes Glass Tube Air Dryer slide, a ten point system to score, fresh semen survival price higher than 0.six, storage of semen survival rate greater than 0.four. Morphological examination of sperm tails
, decapitation, a protoplast, the very first big, double-headed, two-tailed, Orio, etc. are deemed abnormal sperm. The price of boar sperm fine not more than 18%, more than 20% of not appropriate for Insemination.
Inspection would be to decide the concentration of checking the concentration of sperm dilution on the crucial basis of visual observation through the microscope approach, the semen may be divided into dense, medium and sparse three levels. In addition, the board also can be obtained by blood count, sperm density gauge correct calculation of sperm density. The most typically utilised artificial insemination sperm density of 0.five million / ml, insemination of 60 to 80 ml, to make sure efficient sperm 3000000000 ~ 4000000000.
Semen dilution, repackaging, and save the pig semen dilution formula There are numerous, in line with their effects, preservation approaches, and economical decision to choose which. The formula frequently utilized is: glucose 5 to 6 grams of sodium citrate 0.3 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 in general by 1000 ml volume of preparation. OK nicely following dilution, the corresponding diluent into the semen along Beibi slow, slow rock edge chamfer; diluted semen in accordance with all the specifications of separate packaging, the sperm will likely be kept at area temperature 1 to 2 hours slow release soon after 17 temperature in to the refrigerator. Estrus in sows
Insemination match accurately the top quality of sperm transport towards the cervix, the pregnancy price is higher to ensure an essential link in sows. Insemination of specific strategies of operation are: Get rid of the stored semen, Sperm viability inspection, following passing the slow warming to 37 for insemination. Insemination need to sow vagina prior to a clean wipe using a towel, when the very first upward in to the vas deferens, in accordance with anticlockwise cervical arrival in sows.
In brief, the correct use of artificial insemination technology can greatly improve the sow conception price, increase the top quality of pigs to decrease the spread of disease, decrease production costs as well as the majority of farmers to achieve greater financial advantages, is worth promoting.
