Heat stress in sows: hidden consequences for sow and offspring performance

When foetuses develop in a heat-stressed gestation sow, a condition known as in utero heat stress occurs, and piglets may be born smaller with impaired gut microbiome and immune function. Additionally, these piglets show greater susceptibility to stress later in life. Although these consequences are not always immediately apparent, they are important to manage and prevent.
