Topic:Body Mass
Body mass in horses refers to the total weight of an individual horse, which is an important parameter in equine health and management. It influences various aspects of a horse's physiology, including metabolism, locomotion, and overall health status. Accurate assessment of body mass is essential for determining appropriate feeding regimens, medication dosages, and for evaluating growth and development in young horses. Body mass can be measured directly using scales or estimated using body condition scoring systems and weight tapes. This page compiles peer-reviewed research studies and scholarly articles that explore the methods for assessing body mass, its impact on equine health and performance, and its role in the management of different horse breeds and disciplines.
Scaling stride frequency and gait to animal size: mice to horses. The stride frequency at which animals of different size change from one gait to another (walk, trot, gallop) changes in a regular manner with body mass. The speed at the transition from trot to gallop can be used as an equivalent speed for comparing animals of different size. This transition point occurs at lower speeds and higher stride frequencies in smaller animals. Plotting stride frequency at the trot-gallop transition point as a function of body mass in logarithmic coordinates yields a straight line.
Left ventricular function in mammals of greatly different size. Studies of left ventricular volume and pressure have been carried out in the control state in four classes of intact anesthetized mammals (horses, cattle, swine, and dogs), body weights of which varied 54-fold. On the basis of these studies of both large and small hearts, extending over a wide range, a pattern of function for the left ventricle of all mammals has been described. Mathematical equations are given describing the interrelationships between left ventricular end-diastolic volume and end-systolic volume, stroke volume, cardiac output, stroke-work, heart rate, and total peripheral res...
