The extra-uterine life adaptation is a critical period for the newborn. Several changes occur in different organ systems including respiratory function and acid-base balance. The aim of this study was to hypothesize the occurrence of acidosis in newborn kids and obtain blood gas and acid-base parameters of kids in the first 24 hours of life. For this, 33 goat kids of both sexes were used. The blood samples were collected by jugular venipuncture immediately after birth, 5, 10, 15 minutes and 24 hours of life. The blood pH, oxygen partial pressure (pO2), carbon dioxide partial pressure (pCO2), total carbon dioxide (TCO2), bicarbonate concentration (HCO3), base excess (BE) and oxygen saturation (SO2) were determined with a portable blood gas analyzer. Significant differences were observed between the moments in all variables of the kids blood gas values. The newborn kids had respiratory acidosis during the immediate post-partum period, normalizing at 24 hours of life.
