Optimising output per sow
Sow output in Ireland is below that in more efficient pig producing countries. If an Irish 500 sow unit could increase output to that achieved in The Netherlands (26.5 pigs/sow/year), net profit p.a. would increase by €35,650. This would further stimulate growth of the national herd. Welfare and ethical concerns mean that genetic selection for hyper-prolificacy has received negative publicity in other countries where large litters of light, marginally viable pigs are associated with increased mortality. Hence, increases in sow output in Ireland should be achieved in a more sustainable manner. The objective of this project is to increase sow output by:
- Improving sow nutrition (feed allowance, L-carnitine, L-arginine, fish oil, vitamin D supplementation, fermentable substrates) to maximise the sows’ genetic potential for large litters while also increasing the viability of the additional piglets born
- Improving colostrum quality to reduce piglet mortality
- Implementing pre-weaning interventions (nurse sows, rescue decks and energy supplementation) to keep weak piglets alive.
Archived databases from sow nutrition studies will be mined and animal experiments conducted. Best practice guidelines for optimisation of sow output will be prepared and results will be disseminated effectively to enable prompt adoption by stakeholders with the aim of realising Harvest 2020 targets.

- Increasing the number of pigs produced/sow/year using nutritional and management strategies
- Improving the chances of survival of live-born pigs, maintaining the industry mortality average.
