Summary:An abstract of a study by Proctor et al on the effects of in utero heat stress (IUHS) on boar growth and reproduction prior to, during, and after puberty is presented. Confirmed pregnant gilts were subjected to either thermoneutral conditions during gestation or were subjected to relative humidity (RN) from d 1 to 30, heat stress conditions from d 30 to 60, and TN from d 60 until farrowing. Results show that IUHS boars had decreased sperm production, diminished sperm quality, and delayed testicular growth during puberty, indicating the negative repercussions on boar reproduction.
