We have consistently struggled to achieve an acceptable conception rate (90%), especially with our second-litter sows.
We have tried feeding extra food in farrowing, decreasing the number suckling, and giving additional contact with the boars – and the opposite.
But I have always suspected that what we need to do is take them out of production for three weeks to allow time for recovery from the strains of the first litter.
The only issue has been where to house these animals during this period.
Until this week I couldn’t see a solution. But as a result of some of the alterations we have been carrying out, the light bulb came on – and now all I need to do is find the additional gilts to maintain the service levels.

The muck pad has been emptied and the waste straw cleaned up from the pad and removed in anticipation.
We are awaiting the arrival of our newest member of staff at the end of the month. When he gets here we will be able to speed up alterations and spend more time with the stock. I personally cannot wait.
With the current very hot weather my comments last time on growing gills have to be revisited. We now need air conditioning for both staff and stock.
