Electrocardiographic examination in calves: a preliminary study

This study aims to describe and evaluate normal electrocardiographic parameters in calves.Twenty healthy male Holstein calves were included and divided into two groups of 10 animals each. Calves aged between 25 and 30 days have been enrolled in the Group 1. Calves aged between 177 and 183 days have...
