Precision monitoring of reproductive state via development of pen side mucus testing and continuous remote monitoring
Precise detection of ovulation timing is critical for the pig industry in order to maximise production. There is not currently any real time methods that accurately predict when ovulation will occur, to enable optimal timing of artificial insemination. This project aims to develop industry-friendly methods of pre-determining the time of ovulation using pig behaviour and monitoring of changes in cervical mucus the precede ovulation. The project will be conducted in conjunction with collaborators at SARDI and SunPork South.
Bacterial persistence and sperm deterioration in chilled boar semen: Implications for antimicrobial stewardship in Australia
Increasing concern around antimicrobial resistance has led the Food and Agriculture Organisation of the United Nations to identify misuse of antimicrobials in the livestock sector as being a major concern. In light of this, the Australian Pork industry body (Australian Pork Limited; APL) advocates for ‘As little as possible, as much as necessary’ when using antibiotics. One area that falls short of these guidelines is the use of boar semen for artificial insemination, where it is common practice to add antibiotics to storage media. This research aims to characterise the profile of bacteria typically present in Australian boar semen and inform the risk of removing antibiotics from the process.
