- Too often, producers mate gilts who are not yet cycling properly – thinking that they’re second oestrus animals when, in fact, they are still only at first oestrus.
- Gilt culling policies need to be stricter. Around 1 in 10 gilts are sub-fertile so producers should focus on good oestrus detection and then cull the last ones to start cycling. Getting rid of poorer gilts at this stage will reduce low fertility throughout the herd.
