43 Evaluating the use of a monoterpene-based phytogenic supplement to alleviate the effects of gestational heat stress on the sow and her developing offspring Open
The study objective was to evaluate whether a phytogenic supplement would reduce the physiological stress response in heat-stressed (HS) gestating sows, thereby improving growth and welfare outcomes in their piglets following weaning and t…

PSIII-12 Influence of early gestational heat stress on biomarkers of mammary gland development in replacement gilts genomically selected for thermotolerance or thermosensitivity Open
Heat stress (HS) alters physiological and metabolic processes in lactating sows leading to decreased milk production, which is a major factor limiting growth and survivability of piglets. While genomic selection for thermotolerance may be …

22 Feeding the early gestating gilt during heat stress: Implications towards fetal viability, growth, and development Open
Gestational heat stress (GHS) directly impacts litter development and viability and has long term negative postnatal effects on offspring. However, current data on the interactions between GHS, maternal feed energy partitioning, and fetal …

96 Evaluating the impact of macroenvironment temperature on thermoregulatory and milk quality parameters in lactating sows and their litter Open
Farrowing facility macroenvironment temperatures (TMacro) are often maintained at the upper end of the thermoneutral zone (24–25°C) of lactating sows, which may result in heat stress and reduced milk quality and quantity. Therefore, the st…

Plasma γ-Aminobutyric Acid (GABA) Concentrations in Lactating Holstein Cows during Thermoneutral and Heat Stress Conditions and Their Relationships with Circulating Glucose, Insulin and Progesterone Levels Open
Heat-stressed lactating dairy cattle exhibit unique metabolic symptoms, many of which are undoubtedly involved in heat-induced subfertility. Because of its known systemic effects, we hypothesized that γ-aminobutyric acid (GABA) participate…

PSX-18 Determining the Optimal Macroenvironment Temperature to Improve Lactating Sow and Piglet Productivity Open
Pre-weaned piglets prefer higher temperatures than lactating sows. To address this, swine producers use heating lamps or pads in combination with maintaining farrowing room macroenvironment temperatures at the upper end of the thermoneutra…

381 Evaluating Indirect Measures of Milk Production in Heat-Stressed Lactating Sows Genomically Selected for Improved Thermotolerance Open
Lactating sows are among the most heat stress sensitive population in the swine herd. Exposure to high ambient temperatures causes a marked decrease in production measures and welfare in lactating sows and may have a negative downstream im…

PSXIII-B-5 Early Gestation Heat Stress Improved Measures of sow Growth Performance but did not Impact Fetal Growth Open
In utero heat stress negatively impacts fetal development and alters postnatal phenotypes in swine. However, the effects of heat stress (HS) on fetal growth during early gestation is relatively unknown. The study objective was to evaluate …
