Abstract | Pregnancy and parturition are normal physiological conditions that bring about changes in some physiologic parameters, hence the need to establish the electrocardiographic (ECG) parameters and possible changes at different reproductive stages of red Sokoto goat. The research was carried out using twenty red Sokoto goats with a mean age of 2±0.17 years. The does were assessed for pregnancy using ultrasonography. Oestrous synchronisation was conducted using controlled internally drug release CIDR(R) and natural mating was allowed. Bright (B) mode real time ultrasound scanning was conducted using 2.5 MHz sector transcutaneous probe of Vet image 201 ultrasonographic machine of Recorders and Medicare Systems (RMS) (P) LTD to ascertain pregnancy. A single channel electrocardiograph (EDAN VE 100) with a 25 mm/s paper speed and 10mm/mV was used to take the ECG in the standard limb leads (I,II and III) and the augmented limb leads (aVR, aVL and aVF). Comparison of different waves in all the Leads between the periods revealed statistically significant differences in P-wave Amplitude in Leads II, III, aVR, and aVF with postpartum animals having highest records in Leads III, aVR, and aVF, while highest in pregnant animals in Lead II. The P wave duration also differ significantly in the augmented limb leads (aVR, aVL and aVF) with all the records highest in postpartum. There was statistically significant difference in T wave duration in Leads II, III, aVR, aVL and aVF, with highest record in postpartum period in Leads II, III and aVR , while highest records in aVL and aVF were recorded during pregnancy. T wave Amplitude also differs significantly in Leads I, III, aVR, and aVF with highest records in postpartum period in all the significant leads. The QRS interval show statistically significant difference in Leads I, III and aVF with highest record in postpartum period in Leads I and aVF , while highest record during pregnancy was obtained in lead III. Reproductive stages have variable effect on electrocardiographic parameters of the Red Sokoto goat.
