What do I do with this census?

In previous articles we have talked about the importance of a good sow replacement, and we have explained methods to calculate an adequate sow replacement rate. In this article we are going to show an example of a bad replacement policy and its consequences throughout time on the productivity of the farm.

Seasonal effects (temperature and light): analysis and minimization of their consequences

It is a widely documented fact that pig production has seasonal variations mainly focused on a descent in the reproductive efficiency in the gestation phase (difficulty in the coming into oestrus, a higher number of reproductive failures) during the summer and autumn months.
