The piglets born to primiparous sows show a worse performance during the nursery stage and a twofold risk of dying than the piglets born to multiparous sows.
Pig farms data analysis
Small piglets with a low viability are a growing problem, and they represent one of the main causes of pre-weaning mortality.
The improvement in prolificacy seems to be linked, in many cases, to a lower uniformity of the weights at birth.
It's necessary to promote a standardization of the causes of the losses/cullings of the sows. Some rules on which this standardization can be based on are proposed.
The registration of the sow losses/cullings in the management computer programs is normally something easy, but it is not always given the importance that it really has so, sometimes, the registration is incomplete, with wrong dates and without writing down the cause of the loss/culling. Nevertheless, its correct registration and its later analysis can give us very useful information for the correct technical-financial management of the farm.
In a very near future we will have an enormous amount of data with more speed and ease than ever, and also from very different origins.
Only the 17% of the companies use more than the 75% of the collected information and only the 27% of them think that they use it better than their competitors.
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.
