Most calf mortality is due to a serious problem called dystocia. Dystocia is when cows have difficulty birthing due to a large or awkwardly positioned fetus. Dystocia has been a direct link to the failure of the passive transfer of immunoglobulins. Barrier et al. (2013) investigated neonatal physiology, survival, health, and growth of 455 calves following the occurrence of dystocia. Calves delivered during dystocia suffered from higher stress, higher mortality, and reduced transfer of immunoglobulins. In other animals, oxygen therapy is used to improve physiological function and reduce stress, therefore, some research has focused on using supplemental oxygen in dairy calves. Bleul et al. (2008) examined the effects of intranasal oxygen on the respiratory state of neonatal dairy calves. Before and after oxygen was administered, researchers evaluated the arterial partial pressure of oxygen and carbon dioxide and oxygen saturation. Results concluded intranasal oxygen significantly improved the survival rate of calves with respiratory distress. Providing calves with supplemental oxygen post-birth may be used to improve the level of passive transfer of immunoglobulins, save farmers time and money and, most importantly, reduce calf mortality.
