In swine breeding, fourth-site gilts are acquired already pregnant with an average of 40 days of gestation. These animals are being used to supply the production system needs, maintaining the zootechnical indexes, expressed by the number of live, dead and mummified piglets. These indices can be analyzed by the number of weaned piglets/gilts/year, which show that how much more born piglets, more profitability. Besides that, they also demonstrate how these animals went through a process of genetic selection to generate better descents.
