The farrowing interval is one of the production parameters more commonly used as an indicator of the production efficiency of a farm.

Born in Segovia in 1969, Miguel Angel earned a degree in Agronomy with a specialization in animal husbandry from the Polytechnic University of Madrid.
After finishing his studies, he worked for 10 years in the production department of the genetics company, PIC España S.A., carrying out various responsibilities such as consulting farms that used PIC España genetics, and 5 years managing the selection and multiplication nucleus of 5200 sows that PIC España has in the province of Soria.
After leaving PIC España, he began working for PigCHAMP Pro Europa S. L., a multidisciplinary company that services farmers, laboratories and business related with animal production. Within PigChamp Pro Europa, his main responsibility is in the department of management and data analysis, although he also helps in other departments such as the environmental, project testing and veterinary consulting departments.

Which factors affect the WTSI? Among the factors with a biggest influence we have: inadequate intake during lactation, season of the year, and length of the lactation.
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.
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 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.
Normally, when we ask a farmer which is their average number of weaned piglets per sow they normally know this parameter, because its calculation is easy, nevertheless...
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.
