Climate, heat-stress, and genetics impact whole-blood gene expression levels in crossbred pigs
Résumé
As global warming becomes more potent, heat waves and overall temperature increase causes damage to agronomical systems. Excessive heat causes animal welfare and production complications within developed and developing countries.
INRAE designed an experimental cross to study the genetic basis of heat sensibility in pigs. This cross was between the cosmopolitan Large-White race (industrially selected for its growth capacity) and the Creole race, from Guadeloupe, and adapted to tropical environments.
Crossbred offsprings were raised in two distinct climates (n≈180 per environment). Here, we focus on the effects of genetics, climate and heat-stress on gene expression levels in the whole blood.
