1. A method of screening a racehorse candidate, said method comprising:
- (i) obtaining a measurement of the width of the ventricular septal wall of said racehorse candidate; and
(ii) comparing said measurement to a collection of measurements from a group of horses, wherein said collection of measurements comprises ventricular septal wall width measurements for horses of about the same age, sex, and weight as said racehorse candidate.

Abstract
The present invention relates to methods for selecting racehorse candidates. Provided herein are methods for increasing the likelihood of selecting candidates that will be high earners, while reducing the likelihood of selecting candidates that will be low carners, on the basis of certain cardiac measurements.

29. A method of screening a racehorse candidate to select a high earner router, said method comprising:
-
(i) obtaining a measurement of the cross-sectional area of the left ventricle in systole, the cross-sectional area of the left ventricle in diastole, or the percent change in ventricular area per stroke of said racehorse candidate;
(ii) obtaining a measurement of the height×
weight of said racehorse candidate;
(iii) comparing said measurements from said racehorse candidate to a collection of measurements from a group of horses, wherein said collection of measurements comprises height×
weight measurements and cross-sectional area of the left ventricle in systole measurements, cross-sectional area of the left ventricle in diastole measurements, or percent change in ventricular area per stroke measurements from horses of the same age, weight and sex as said racehorse candidate.

30. A method for maintaining a horse registry system for identifying the potential racing ability of a candidate racehorse, the method comprising:
-
(i) obtaining measurements from a group of horses;
(ii) standardizing said measurements for age, sex, and weight;
(iii) classifying said horses according to their racing abilities; and
(iv) determining the relationship between the measurements of said horses and their racing ability. - View Dependent Claims (31)

32. A method of screening a racehorse candidate, said method comprising:
-
(i) obtaining an echocardiographic image of the heart of said racehorse;
(ii) rating the image according to at least one cardiac parameter selected from the group consisting of the general shape of the heart at diastole and systole, the clarity and sharpness of contrast of left ventricle during diastole and systole, the smoothness of the left ventricle during diastole and systole, blood backflow from the left ventricle during diastole and systole, valve closure, and clarity of the image in diastole; and
(iii) comparing the rating to a collection of ratings of the same cardiac parameter from a group of horses of about the same age, sex, and weight of said racehorse candidate.
