Relationship Between Age, Gender, Height, Body Condition Score, and Body Weight in Thoroughbred Yearlings Raised in Kentucky

Forty years ago, Henneke and coworkers developed a body condition score (BCS) system for horses that is widely used today. This system applies a score of 1 to an emaciated horse and a score of 9 to an extremely obese horse. The system was originally designed to measure BCS in Quarter Horse broodmares, but it […]

Factors Affecting Birth Weight in Thoroughbred Foals Born in Kentucky, United Kingdom, and Australia

Kentucky (KY), United Kingdom (UK), and Australia (AUS) are major breeding regions for Thoroughbreds. Birth weights (BW) are commonly measured in each region and are perceived as important parameters for assessing foal health and future athletic ability. This study was conducted to evaluate how foal BW is affected by gender, mare age, parity, month of […]

Race Training Improves Skeletal Muscle Mitochondrial Volume Density, Function, and Capacity in Thoroughbreds

Racehorses are among the most elite athletes in the equine industry. However, little is known about mitochondrial adaptations to race training. To test the hypothesis that race training increases mitochondrial biogenesis and capacity, gluteus medius samples were collected from Thoroughbred horses (11 geldings, 2 mares) before and after 14 wk of early race training. Horses […]

Growth and Development of Thoroughbred Horses

Research into the growth and development of Thoroughbreds managed on commercial breeding farms is reviewed in this paper. Because horses are not meat-producing animals, less research has been performed quantifying growth, muscle, and bone development than with other production animals. However, variations in growth and development are linked with both value and wastage in young […]

A Supplement Containing Marine-Derived Minerals Increases Bone Density in Thoroughbred Racehorses in Early Training

Bone density and strength are important for the long-term health and soundness of performance horses. Marine-derived mineral complexes improve bone density and strength in laboratory animals and humans. Additionally, nutrients without established requirements in horses, such as boron, silicon and vitamin C, may affect bone health. This study evaluated the effect of feeding a supplement […]

Body Weight, Wither Height And Growth Rates In Thoroughbreds Raised In America, England, Australia, New Zealand, And India

The purpose of this study was to obtain growth data from populations of Thoroughbreds born and raised in various countries and compare body weight, daily weight gain, and wither height growth curves. Information was collected for the years 1996 to 2006. A linear regression model with foal age as the explanatory variable and country as […]
