A study conducted at the Faculty of Veterinary Medicine and Animal Science (FMVZ) at USP, in collaboration with other universities, has revealed that the gestation environment of female pigs can significantly influence the development of the piglet's brain. The research indicates that pigs kept in uncomfortable environments during pregnancy are more likely to exhibit repetitive behaviors (stereotypies) in their offspring, with epigenetic changes observed in areas of the brain linked to emotions. This study highlights the importance of providing an enriched gestation environment for pigs to improve their welfare and that of their offspring, as Brazil has banned the use of gestation crates by 2045. The findings were published in the scientific journal Epigenetics and were supported by the São Paulo State Research Support Foundation (FAPESP) and the Coordination for the Improvement of Higher Education Personnel (CAPES).
