ESTRUS SYNCHRONIZATION AND ARTIFICIAL INSEMINATION IN PIGS.
The successful artificial insemination of sows depends on the hygienic deposition of enough sperm at the appropriate time so as to have an adequate sperm reservoir in the oviduct at the time of ovulation. The time of natural ovulation is controlled by the surge of Lutenizing Hormone near the onset of estrus. Ovulation will occur in 85 to 90 percent of sows 42 +/- 2 hours after an injection of human chorionic gonadotrophin (hCG) or 38 ± 2 hours after gonadotrophin-releasing hormone (GnRH).
If ovulation is expected to occur 38 or more hours after detection of estrus, such as would be expected following a gonadotrophin-induced estrus or naturally short wean-to-estrus intervals, treatment with GnRH or hCG will provide a high degree of predictability to the time of ovulation.
Recent research shows that 200 μg of triptorelin given intra-vaginally to sows at 96 hours after weaning synchronizes ovulation and results in fertility with number of live born pigs and farrowing rate similar to controls.
There are considerable economic benefits of the use of single fixed-time insemination, with the most obvious being the cost savings from the reduction in breeding time and labor. The overall advantage will be having a number of litters per time on farm which will result in proper management and an all in all out strategy. The cost of housing and feeding of boar is also reduced as highly productive boars are sourced and the quality and quantity of sperm weighed against physical mating cannot be compared. The sperm can also be procured from proven stock,hence eliminating the need for your own boar thus saving time and money with regards to management.
An artificial insemination parlor will also be an innovative startup in pig industry,where genetically proven boars are fed and raised on a separate facility with the sole aim of operating a sperm bank, with proven genetic traits .
