The objective of this study was to assess the effects of THI during month of foaling on the duration of gestation of Thoroughbred mares. The gestational length of 437 pregnancies of 279 Thoroughbred mares carrying and delivering normal singleton foals were recorded and analyzed during four foaling seasons of the Southern Hemisphere.
