Assessment of electrocardiographic parameters of Red Sokoto goats

Abstract

The study was necessitated due to the economic importance of Red Sokoto goat, its resilient nature and limited literature on electrocardiographic parameter of the breed. The research was conducted using thirty goats comprising of 15 does and 15 bucks within the ages of 1-3 years and an average weight of 35kg. Electrocardiographic parameters were recorded using the three standard limb leads (I, II and III) as well as the  augmented limb leads (aVR, aVL and aVF). Various forms of negative and positive wave deflections were recorded. Positive P and T waves were predominant in all the leads (standard limb leads and augmented leads). Typical QRS complex was predominant in all the leads with little qR in leads II, III and aVF. The mean electrical axis was between -178° and +170°. Cardiac rhythm was determined using P wave orientation and most of the animals had sinus rhythm. The mean heart rate was 141 ± 4.8 beats per minute and ranged from 92 to 164. The various forms of  electrocardiographic waves recorded in Red Sokoto goat differ from those of other breeds of goats. The records obtained suggest that Red Sokoto goat has faster cardiac electrical conduction.
