Porcine reproductive and respiratory syndrome (PRRS) is a viral disease that causes a decrease in reproductive performance in breeding animals and respiratory disease in pigs of any age. PRRS is the most economically significant disease affecting swine production in the world today.
SOUTH KOREA - The Fourth Asian PRRSpective opened yesterday in South Korea's Jeju Island to update Asian pig farmers on the latest scientific research on PRRS and effective solutions in keeping it under control.
In hyperprolific sows with the potential to produce large litters, gestation length will typically last for 3 months, 3 weeks and 3 to 5 days. The more foetuses present, the less room there is for adhesion of the placenta of each individual pig to the uterine wall. To facilitate maximal embryonic development, it is important that the sow is optimally nourished prior to insemination. Also it is important to recognise and minimise stress factors such as fluctuations in environmental temperature, social stress such as fighting and exposure to toxins and infections e.g. PRRS. In hyperprolific sows particularly, these factors have significant negative impact on the forthcoming gestation.
