Larsen and Laporta evaluated the effects of heat stress of the dairy cow on the second generation of dairy cows. 

• The daughter’s (F₁) of a mother (F₀) exposed to heat stress (shade only for heat abatement) in late-gestation produced less milk in their first lactation
•  The grand-daughter’s (F₂) also had reduced lactation compared to the grand-daugther’s of cows that had access to shade and active cooling via fans and water soakers
•  Otherwise, the grand-daughter’s of mother’s exposed to heat stress had no difference to the control group: same growth trajectories, dry matter intakes and phenotype of the mammary gland
