The reference database of the Spanish swine sector has made a study of the main productive and reproductive variables of Spanish pig farms between 2010 and 2016 (more than 850,000 sows are part of BDporc). This study includes statistical graphs that you can see in the link we attach.
We hope you find it interesting in spite of the fact that the article is not translated into English.
