Swine Artificial Insemination Procedures

As the swine market scale and intensive amount of continuous improvement, breeding sows includes a direct effect around the amount of the financial benefits of farmers. To raise the level of sow breeding probably the most direct and successful way would be to use Artificial Insemination. Artificial insemination technology not only can significantly improve the conception rate of sows to accelerate the pace of improvement of pig breeds, and promote the improvement of pig production levels, but in addition substantially reduce the number of boars in the breeding and minimize fees. Artificial insemination of pigs in Incubator China within the early 50s from the 20th century a small number of institutions of greater studying, scientific analysis units to test the late 70s far more widely used inside the production, and achieved good impact. But our existing artificial insemination price of about 30% of the developed countries and 60% to 85% possess a gap, consequently, also vigorously promoted. The procedure of artificial insemination have the following measures:

Prepared prior to semen collection semen room 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 gear placed at 40 incubator preheated (except in summer season); microscope regulate the focal length, maintaining the temperature boxes microscopy 35 ~ 37 , containing Holes Glass Tube Air Dryer film and in to the microscope coverslip box preheat; ready warm Baking Water Bath about 25 .

Boar semen collection wrapper about the lengthy hair cut, circumcised crowding, the inner solution in urine, employing a damp cloth dipped in potassium permanganate Baking Water Bath back a single way by the circumcision mouth clean. Semen release are usually straightforward to utilize the hand technique. The donor members must wear latex gloves, the boar semen collected in collection cup fine, fine cup set with 2 to four layer gauze hooded filtration at area temperature with low thermal insulation wants to set the cup, then speedily test area inspection, diluted and may be stored.

Clear liquid Good quality Inspection Visual inspection semen normal gray or white color, the greater the concentration the far more the color white; typical smell slightly fishy smell, or smell; generally weakly alkaline or neutral. Determination of sperm vitality

verify is always to make certain that sows impregnated a crucial technology. Certain approaches of operation are: semen drops within the 38 constant temperature in the Holes Glass Tube Air Dryer slide, a 10 point system to score, fresh semen survival rate greater than 0.six, storage of semen survival price greater than 0.four. Morphological examination of sperm tails

, decapitation, a protoplast, the first big, double-headed, two-tailed, Orio, and so on. are regarded abnormal sperm. The price of boar sperm fine not greater than 18%, more than 20% of not suitable for Insemination.

Inspection is usually to determine the concentration of checking the concentration of sperm dilution from the critical basis of visual observation by means of the microscope method, the semen can 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. Essentially the most generally utilized artificial insemination sperm density of 0.five 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, in accordance with their effects, preservation strategies, and economical selection to determine which. The formula typically used is: glucose 5 to six grams of sodium citrate 0.3 to 0.five grams of EDTA or EDTA 0.1 g, enhanced to 100 ml with distilled Baking Water Bath, the scale of pig farms generally by 1000 ml volume of preparation. OK nicely following dilution, the corresponding diluent in to the semen along Beibi slow, slow rock edge chamfer; diluted semen in accordance together with the specifications of separate packaging, the sperm will likely be kept at space temperature 1 to 2 hours slow release after 17 temperature into the refrigerator. Estrus in sows

Insemination match accurately the high quality of sperm transport for the cervix, the pregnancy price is high to ensure an important link in sows. Insemination of distinct techniques of operation are: Get rid of the stored semen, Sperm viability inspection, following passing the slow warming to 37 for insemination. Insemination should sow vagina ahead of a clean wipe using a towel, when the first upward into the vas deferens, in accordance with anticlockwise cervical arrival in sows.

In quick, the proper use of artificial insemination technologies can significantly boost the sow conception price, boost the quality of pigs to lessen the spread of illness, decrease production costs as well as the majority of farmers to achieve higher economic benefits, is worth promoting.
