In order to keep the population of the different kinds of animals constant, the flows of pigs must be constant. This is, we must keep the production pace of the farm.
Pig farms data analysis
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.
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.
