Two-dimensional speckle tracking is feasible in calves and as in other species systolic radial function can be more reliably evaluated than circumferential and diastolic function. Hyperlactatemia, hypercapnia, low pH and low O 2 sat are commonly observed in premature calves. Effect on mortality of venous Lactate, pH and pCO 2 Levels in 110 premature calves with Respiratory Distress Syndrome (RSD) was investigated in the study. The study was performed between 2010 and 2014. All premature calves were admitted to the clinic within 24 hours after birth. In addition to short gestational age, clinical signs of low birth weight, including an inability to stand, short and silky hair, and incomplete eruption of the incisor teeth were also present in the premature animals. Ninety-four of the premature calves were Holsteins, 16 were Swiss-Browns; and 42 were bull calves. Blood samples were collected anaerobically into heparinized tubes from the jugular vein and measured immediately using a blood gas analyzer. Data were expressed as means and standard deviation (Mean AE sd). Independent samples T test was used to compare the venous blood gas indicators of surviving and non-surviving premature calves.
