Body Measurements:
- Body Length (BL)
- Chest Width (CW)
- Thorax Depth (TD)
- Thorax Perimeter (TP)
- Head Length (HL)
- Head Width (HW)
- Neck Length (NL)
- Leg Length (LL)
- Shoulder Length (SL)
- Knee Perimeter (KP)
- Cannon Bone Perimeter (CP)
- Croup Length (CL)
- Point of Hip-Stifle Distance (HSD)
- Femur Bone Length (FL)
Linear Conformation Traits:
- Knee Frontal Angle (KFA)
- Knee Lateral Angle (KLA)
- Factors such as breeder, age, sex, coat color, and inbreeding had significant effects on the conformation traits.
- The results suggest that early selection of PRE horses based on foal conformation could be a reliable and cost-effective strategy for predicting adult performance traits.
- Genetic correlations between the same traits in young and adult horses were above 0.75 for most traits, indicating strong predictability of adult conformation from foal measurements.
