How Much Weight?

A question which frequently arises is the amount of weight a horse should or can carry. The rule to ascertain the carrying power ( in pounds) of a horse is to divide his body weight by 5.757, and add to this 28 lbs. A general rule is a horse can eat 15 - 20 % of its own body weight. For an example a 1200 lb. horse can carry approximately 180 to 240 pounds.

A recent report from the University of Kentucky Livestock Disease Diagnostic Center in Lexington, KY suggests the many different conditions affecting older horses. The study indicated a greater longevity for pony breeds. The majority of conditions pertained to gastrointestinal, musculoskeletal and reproductive systems. (Figure 3.)

In general, infectious diseases are an important cause morbidity and mortality in horses. However, infectious diseases were a much less common cause of illness in geriatric horses compared to conditions that were anatomical, traumatic, or neoplastic in nature. Only approximately 10-15 % of all diagnoses had an infectious etiology. These were most commonly pneumonia and enteritis cases.

Some basic recommendations can be made to owners of geriatric horses. To reduce the incidence of gastrointestinal disorders horses should be fed diets with ample high quality roughage and that abundant water and appropriate exercise are provided.

Regular deworming and dental care are also essential in older horses to help ensure optimal gastrointestinal function. The environment should be policed for hazardous areas and stocking rates should be appropriate for pasture.

Older foaling mares, especially following difficult deliveries, should be closely monitored and veterinary assistance sought immediately if undue pain or signs of shock are observed.
