The development and approval of a new generation of reproductive hormones for advancing and synchronizing ovulation in swine has been attracting attention for their application use of single fixed-time insemination (SFTI). The technology is based on the administration of a hormone to sows after weaning and is followed by only one timed insemination the next day.

Data for on-farm performance shows similar fertility to standard breeding protocols based on conventional artificial insemination (CAI) involving estrus detection and multiple inseminations. However, changing from a well-established CAI procedure to a new breeding protocol is likely to raise questions and concerns.
To help pig producers understand the new technology, this article discusses some areas of change, risk and reward, as well as answers these questions:
- How does hormonal control of ovulation work?
- What hormones are used to synchronize ovulation?
- When using SFTI, will one insemination really work?
- On farms with good reproductive performance, what benefits can SFTI bring?
- Are there different options for implementing the SFTI technology on my farm?
- What metrics should be considered in order to measure the success of SFTI?
