Swine Artificial Insemination Procedures

As the swine sector scale and intensive degree of continuous improvement, breeding sows has a direct impact around the degree of the economic benefits of farmers. To raise the degree of sow breeding probably the most direct and successful way would be to use Artificial Insemination. Artificial insemination technologies not just can greatly enhance the conception rate of sows to accelerate the pace of improvement of pig breeds, and promote the improvement of pig production levels, but also drastically minimize the number of boars within the breeding and minimize charges. Artificial insemination of pigs in Incubator China inside the early 50s of the 20th century a little quantity of institutions of greater learning, scientific study units to test the late 70s more extensively utilized in the production, and accomplished very good impact. But our present artificial insemination rate of about 30% on the developed countries and 60% to 85% possess a gap, for that reason, also vigorously promoted. The process of artificial insemination possess the following methods:

Ready before 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 as well as other gear placed at 40 incubator preheated (except in summer season); microscope regulate the focal length, keeping 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 about the extended hair cut, circumcised crowding, the inner product in urine, utilizing a damp cloth dipped in potassium permanganate Baking Water Bath back one way by the circumcision mouth clean. Semen release are usually basic to work with the hand technique. The donor members need to wear latex gloves, the boar semen collected in collection cup fine, fine cup set with two to four layer gauze hooded filtration at area temperature with low thermal insulation demands to set the cup, then swiftly test room inspection, diluted and may be stored.

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

verify is usually to make sure that sows impregnated an essential technology. Particular approaches of operation are: semen drops within the 38 constant temperature in the Holes Glass Tube Air Dryer slide, a ten point method to score, fresh semen survival price greater than 0.6, storage of semen survival price higher than 0.four. Morphological examination of sperm tails

, decapitation, a protoplast, the first big, double-headed, two-tailed, Orio, etc. are considered abnormal sperm. The rate of boar sperm fine not more than 18%, greater than 20% of not appropriate for Insemination.

Inspection would be to establish the concentration of checking the concentration of sperm dilution from the crucial basis of visual observation via the microscope strategy, the semen can be divided into dense, medium and sparse 3 levels. Furthermore, the board also can be obtained by blood count, sperm density gauge correct calculation of sperm density. Probably the most frequently utilized artificial insemination sperm density of 0.5 million / ml, insemination of 60 to 80 ml, to ensure powerful sperm 3000000000 ~ 4000000000.

Semen dilution, repackaging, and save the pig semen dilution formula There are many, according to their effects, preservation techniques, and economical option to determine which. The formula frequently employed is: glucose five to six grams of sodium citrate 0.3 to 0.five grams of EDTA or EDTA 0.1 g, improved to 100 ml with distilled Baking Water Bath, the scale of pig farms in general by 1000 ml volume of preparation. OK nicely right 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 probably be kept at room temperature 1 to 2 hours slow release after 17 temperature into the refrigerator. Estrus in sows

Insemination fit accurately the quality of sperm transport for the cervix, the pregnancy rate is high to make sure an essential link in sows. Insemination of distinct methods of operation are: Get rid of the stored semen, Sperm viability inspection, following passing the slow warming to 37 for insemination. Insemination ought to sow vagina before a clean wipe using a towel, when the 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 drastically boost the sow conception price, increase the top quality of pigs to minimize the spread of illness, reduce production fees and also the majority of farmers to achieve higher economic rewards, is worth advertising.
