Gestational heat stress and phytogenic supplementation influence sow growth, bioenergetics, thermoregulation, and subsequent offspring resilience

Abstract The study objectives were to determine whether a phytogenic supplement reduced physiological stress in heat-stressed (HS) gestating sows and to evaluate how HS alters maternal growth responses and postweaning growth and stress responses in their piglets. Twenty-six pregn...

Material consequences: An initial assessment of the influence of flooring type on lactating sow thermoregulation in summer heat

Abstract Heat stress (HS) impairs lactating sows’ ability to provide adequate nutrition for their litters, prompting the development of management practices and new housing systems to alleviate its effects. However, few have investigated materials used in farrowing crate construc...
