Venous blood gas parameters in healthy Mediterranean buffalo calves in the first 72 hours of life.

In the first hours after calving the neonate radically modifies its anatomy and physiology to adapt to extrauterine life. These modifications, however, make the calf prone to respiratory and metabolic dysfunction. Thus, stillbirth, defined as the death of the neonate within 48 h after birth, represents a relevant issue for buffalo farming. Of the clinical procedures, the blood gas analysis of venous samples provides useful information regarding the acid-base status of the neonate, allowing the optimal management of potential illness calves. However, the blood gas parameters have never been studied in the buffalo calf in the first 72 h of life. Thus, this study aimed to report blood gas parameters at calving and 1, 12, 24, and 72 h after birth in healthy buffalo neonates born after normal parturition. The study involved 20 healthy buffalo calves, born from normal pregnancy and parturition. The parturition and the first hours after were monitored by closed-circuit television cameras, and within 1 min after calving the buffalo neonate received a clinical evaluation (APGAR, temperature), venous blood sampling for blood gas (pH, partial pressure carbon dioxide - pCO
