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 . # gene pool # sperm bank # Artificial insemination bank # boar farm # stud startup.

GENETICS AND PIG PRODUCTIVITY.

Improving genetic lines not only improves production but it creates disease free/resistant lines that maintains herd health and ensures profitability.A lot of pig producers sort and select breeds that will be stable in their environment and produce optimally,this they often do by importing breeding stocks or crossing various lines to come up with that that is suitable for their environment. A pig breeding network in Thai is producing genetic lines that are suitable and adaptable to Asian countries; The siam pigs run by Dr Sakchai Topanurak, Chulalongkorn University and major driving force behind SiamPigs. The goal of SiamPigs' is not only to improve production performance, but also to solve endemic and chronic herd health problems. This concept was borne out of the fact that Western pig breeds do not always come fully prepared for the Asian reality as they are full of various pathogens and different market needs,the need to select genetic lines that are resistant to disease and yielding higher lean meat percentages. The operations of breeding systems ensures a nucleus herd is free from diseases. Genetics from a high health breeding nucleus will subsequently be distributed to a production herd. Breeders lower in the breeding pyramid of course always try to keep their production herds as free from diseases as a nucleus herd would be – and also try to maintain similar high health standards, e.g. by applying strict bio security measures. This is done to enable the pigs to perform to their full genetic potential so that they can deliver effective and competitive products. SiamPigs, established in Thailand, is a network of pig producers using improved genetics, disease tolerant and disease resistant pigs as a tool. The group's goal is not only to improve production performance, but also to solve endemic and chronic herd health problems. Many pig farms have successfully reduced the risk of infection from outside the farm by applying a model that revolves around the principle of 'one nucleus, one farm' . SiamPigs developed its own breeds – Duroc line 929, Large White line 7788, Landrace line 4701 and Siam Kurobuta, with the productivity of the network's members being on par with the world's top producers. Farms in the network vary in size, starting from 400 to more than 10,000 sows. The network covers more than 100 farms in Thailand, with over 250,000 sows using breeding stock and semen developed by SiamPigs.

HOUSING PIGS IN STYLE!!!

Pigs housed in beautiful and conducive environment,grow faster, better and are less prone to diseases. The role of housing in production can not be over emphasized,look at how pigs are housed for better productivity; look at the Cavite pig city; Read more here;http://www.pigprogress.net/Growing-Finishing/General/2015/9/Cavite-Pig-City-A-city-within-a-city-2673896W/
