Help to Reduce Infertility Risk04 September 2012
UK - Sows and gilts that are served from mid-September to late October may suffer from infertility problems including delayed oestrus, increased returns and abortions.
Predisposing factors include sows being weaned in poorer conditions, warm days, cool nights and decreasing day lengths. There are some things you can do to minimise the risk:
- Minimise draughts and ensure any cracks in ceilings and around doors are sealed
- Increase the amount of bedding being used
- Feed sows and gilts to body condition
- Re-instate the winter feed curve
- Provide 14 to 16 hours of light per day, of a minimum of 200 lux, from the beginning of August. Install a light timer, consider introducing more lights into dark houses and wash existing bulbs. Whitewashing walls/tents will also reflect light
- Provide more physical boar contact pre- and post-service to provide ongoing support for the maintenance of pregnancy and to detect cycling sows.
