Changes in cortisol and cortisone in hair of pigs under heat stress
The use of cortisone and the estimation of 11β-HSD type 2 activity in hair is recommended instead of using hair cortisol concentrations alone.

Effect of drying and warming piglets at farrowing on preweaning mortality
Drying and warming the piglets favors their survival only in farrowing units with moderate or suboptimal temperatures (<25ºC).
IHT Group to manufacture, sell hog-cooling technology developed at Purdue
Patented cooling pads developed by animal science experts keep boars and sows cooler, improve their feed intake and milk output, and increase piglet wean weight.
Impacts of evaporative pad cooling on finishing pig performance
Cool cell pads improved pig well-being by providing more cooling than sprinklers but pig performance was unaffected.

These results suggest electric-heated mats and heat lamps were comparable in maintaining the performance and postural behaviors of piglets.
Heat stress affects the sows' reproductive cycle
From their respective academic and on-farm perspectives, Josep Gasa and Josep Casanovas comment on a recent study regarding the effect of heat stress on sows: Which weeks does it affect the farrowing rate the most? What about the weaning-to-first-service interval? Are there differences depending on parity?
