Electrocardiographic analysis of ST-segment duration and morphology in sheep and goats: Effect of species,breed,age and sex

The importance of obtaining normal values of st-segment for specific breeds of animals besides the high variability of indices in small ruminant has been emphasized. the animals were assigned into 4 groups (g1-4),according to their age: g1<3 months,3 months ≤g2< 1 year,1 year≤g3<3 years,and g4 ≥ 3 years old. there were 34 animals in each study group. the animals were assigned to two comprising groups: sheep,goat,male and female. also,the animals were divided into three groups according to their breed,including: kermani sheep,saanen and cashmere (raini) goats. the present study showed that sex,age and breed had no effect on st-segment in sheep and goats and the obtained data can provide a good basis for judging the st-segment length and morphology in difference sexes,breeds and age groups of sheep and goats.
