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 […]

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 […]

Nutritional Management and Feeding of Sick and Hospitalized Horses

When a horse arrives at a veterinary hospital, several nutritional or feeding challenges may be encountered. Feeding programs should aim to avoid weight loss, unless it is required for a specific condition (e.g., equine metabolic syndrome). Negative energy balance can lead changed intestinal microbiota, reduced immunity, and increased incisional complications. Some horses with peracute or […]

The Need For and Production Of Quality Forage Feeds

Horses have evolved over millions of years as roaming grazing animals, and they have specialized digestive tracts adapted to digest and utilize diets containing high levels of plant fiber. They are capable of eating and processing large quantities of forage to meet their nutrient demands. In an attempt to maximise growth or productivity, horses are […]

Feeding and Management Practices for Racehorses in Turkey

The aim of this study was to gather information on feeding practices and to identify nutrient imbalances of racehorses in Turkey. A total of 134 racehorses who visited the Turkish Jockey Club Racecourse Equine Hospital in Istanbul were referred for professional nutritional advice in 2013. Each horse was examined, and body weight (BW), body condition […]

Nutrition: Key Issues and the Consequences of Getting Them Wrong

Large investments in horses are made in China annually, but the wastage rate due to poor performance, slow growth, suboptimal body condition, colic, lameness, infertility, and other disease is high. Ten key issues related to nutrition and feeding horses in China have been identified as possible contributors to this wastage. These issues include lack of […]

Pasture-Associated Stringhalt: Contemporary Appraisal of an Enigmatic Syndrome

Although described clinically for several centuries, stringhalt remains an intriguing and enigmatic condition. In pasture‐associated stringhalt (PSH), the clinical sign of exaggerated, prolonged hindlimb flexion is associated with a peripheral neuropathy affecting the larger myelinated axons that is thought to be the result of exposure to a plant‐derived neurotoxin. Multiple host and environmental risk factors […]

Mineral and Vitamin Supplementation Including Marine-Derived Calcium Increases Bone Density in Thoroughbreds

Bone quality is important for the long-term health and soundness of performance horses. In racehorses, insufficient bone density is associated with shin soreness, an important cause of lost training time and reduced starts, as well as other aspects of bone fatigue. Risks of injury during training are associated with insufficient bone density. Research has previously […]

Nutrient Content of Australian Horse Pastures—Effect of Season

Most Australian horses rely on pasture for some of their nutrient intake, and many are just on pasture without supplementary feed for some part of the year. To determine the nutrient intake of horses on pasture for comparison with recommended daily allowances, nutritionists need to know not only the pasture intake but also the nutrient […]

Nutrient Content of Australian Horse Pastures—Nutrient Intakes Compared to Requirements

Most Australian horses rely on pasture for some of their nutrient intake, and many are just on pasture without supplementary feed for some part of the year. To determine the nutrient intake of horses on pasture for comparison with recommended daily allowances, nutritionists need to know not only the pasture intake but also the nutrient […]
