SUMMARY Sixty Yorkshire, Hampshire and Yorkshire • Hampshire gilts and sows were used to study changes in respiratory rate and rectal temperature before, during and after parturition. Measurements began around 12 hr before birth of the first piglet was anticipated and continued at hourly intervals until 12 hr after parturition. Ambient temperature was 20 C_+3. Data for each female were averaged over five periods: (A) 24 to 12 hr before birth of the first piglet, (B) 12 to 4 hr before birth of the first piglet, (C) 4 hr before birth of the first piglet, (D) parturition, and (E) 24 hr after birth of the last piglet. Respiratory rate was highest ( P < . 0 5 ) d u r i n g p e r i o d B. Respiratory rate (breaths rain -1, mean +SE) during periods A, B, C, D and E was, respectively: 54+7, 91+4, 72_+4, 35_+3 and 25_+3. Rectal temperature was higher (P
