Estimation of Actual and Ideal Bodyweight Using Morphometric Measurements of Miniature, Saddle-Type, and Thoroughbred Horses.
Abstract: Adding breed type, height, and neck circumference to body length and girth circumference improves bodyweight (BW) estimation in different breeds of horses; however, equations have not been developed for all breed types. The objectives were to develop BW estimation equations for Miniature, saddle-type, and Thoroughbred horses using morphometric measurements. Measurements were collected on adult (≥3 years, nonpregnant) saddle-type (n = 209), adult (n = 249) and juvenile (<3 years, n = 61) Miniatures, and adult Thoroughbreds (n = 100). Personnel determined body condition score (BCS), measured withers height and girth circumference at the third thoracic vertebra, body length from the point of the shoulder to the point of the buttock and to a line perpendicular to the point of the buttock, and neck circumference at the midway point between the poll and withers. Each horse was weighed using a livestock scale. Bodyweight estimations equations were developed using linear regression modeling and log transformation. Mean (±standard deviation) BCS was 6.1 (±0.8), 5.4 (±0.6), 6.0 (±1.0), and 5.0 (±0.6) for adult and juvenile Miniatures, saddle-type, and Thoroughbreds, respectively. Bodyweight estimation equations developed through the current research were within 4% of the scale BW and offered improvements over previous BW estimation equations and weight tapes, which were off by 5%-25%. Owner-estimated BW was within 8%-15% of scale BW. Morphometric measurements were successfully used to develop BW equations for Miniature, saddle-type, and Thoroughbred horses. The equations will assist owners and professionals with managing horse BW and will be added to the Healthy Horse application.

Summary
This research summary has been generated with artificial intelligence and may contain errors and omissions. Refer to the original study to confirm details provided. Submit correction.
The study developed new equations for estimating the body weight of miniature, saddle-type, and thoroughbred horses by incorporating accurate morphometric measurements including breed type, height, and neck circumference. The new equations significantly enhanced the accuracy of weight estimation in these horse breeds compared to traditionally used methods.
Objective and Methodology of the Study
- Estimation of actual and ideal bodyweight in horses is crucial for their proper management and care. Despite the previous attempts to create equations for bodyweight (BW) estimation, no universal solution has been found as those equations were not covering all horse breeds.
- The research aimed to create more reliable and standard BW estimation equations for three specific breeds of horses – Miniature, saddle-type, and Thoroughbred horses – based on their morphometric measurements.
- Measurements were taken from adult and juvenile Miniatures, saddle-type, and adult Thoroughbreds. The data collected included body condition score (BCS), withers height, girth circumference at the third thoracic vertebra, body length, and neck circumference.
- Each horse’s actual bodyweight was measured using a livestock scale for comparison purposes and the linear regression modeling and log transformation were used to develop the estimation equations.
Main Findings and Implications
- The equations developed through the research were effective in improving bodyweight estimations of the tested horse breeds, offering an accuracy within 4% of the scale bodyweight.
- This proved to be a considerable improvement over the previous bodyweight estimation methods, such as weight tapes or owner estimations, which could differ from the actual weight by 5%-25% and 8%-15% respectively.
- This study is important as these new equations will assist horse owners and professionals in more accurately managing horse bodyweight.
- In practical terms, the equations will be added to the Healthy Horse application, a software helping horse owners and professionals manage equine health and nutrition.
