[ECG similarities in the parents and offspring of thoroughbred horses].

This research studied the Electrocardiogram (ECG) traits in two thoroughbred horse sires, their offspring, and one mare with her daughters, revealing the hereditary transfer of certain ECG characteristics in these horses.

Introduction

• The study investigates ECG characteristics in a set of thoroughbred horses. Specifically, it focuses on two sires named Manrico and Infernal, their 26 offspring, and a mare named Victoire with her five daughters.
• The main objective of the research is to observe and understand any similarities that may exist in the ECG traits of the parents and offspring.

Findings

• The study demonstrates the inheritance of certain ECG characteristics from the sire (father) as well as the dam (mother) to the offspring.
• This consistency in ECG traits is particularly noticeable in the sire Manrico and his offspring, as well as in the mare Victoire and her daughters. These traits include the inclination of the electric cardiac axis, intrinsicoid deflexion lag, P wave shape, and deep S in the 3rd connection.

Implications

• The findings suggest that there is a hereditary component involved in the passing down of specific ECG characteristics, which could be used for breed selection and in veterinary medical interventions.
• This deeper understanding of the genetic influence on ECG traits in horses could contribute to the fields of equine genetics, breeding, and veterinary cardiology.

Conclusion

• The research successfully established the transmission of ECG traits from parents to offspring in thoroughbred horses, revealing that certain ECG characteristics are maintained across generations.
