This study was designed to determine the effects of fat adaptation on carbohydrate and fat oxidation in conditioned horses during low-intensity exercise.

The purpose of this study was to examine the effects of an external nasal strip (NS), frusemide (FR) and a combination of the 2 treatments (NS + FR) on exercise-induced pulmonary hemorrhage (EIPH) in Thoroughbred horses. It was hypothesized that both the NS and FR would attenuate EIPH as assessed by red blood cell count in bronchoalveolar lavage fluid.

Very little research has been conducted to determine the trace mineral requirements for athletic horses. The objectives of this study were to
1) determine the digestibility and retention of copper, zinc and manganese over four different levels of intake (basal, 50% of NRC added, 100% of NRC added, and 200% of NRC added) and 2) determine how regular exercise and training alters the requirements for these trace minerals. Results of the present study suggest that exercise training results in a higher requirement for Zn, but does not affect the true digestibility and maintenance requirements of Cu and Mn in mature Thoroughbred horses.

To delay the onset of fatigue, endurance horses are often fed at rest stops during races. The resulting increase in blood insulin may adversely inhibit lipolysis. In humans, ingestion of fructose produces a smaller insulin rise than glucose. This study compared glucose and fructose as carbohydrate supplements for endurance horses.

To determine the effects of 3 rations (low grain, fat, high grain) on plasma creatine kinase (CK) activity and lactate concentration in Thoroughbred horses with recurrent exertional rhabdomyolysis (RER). Rations high in grain and formulated to exceed daily energy requirements may increase episodes of rhabdomyolysis in thoroughbred horses susceptible to RER.

High-grain diets for the exercising horse were compared with diets which provided 15% of the total caloric intake from either vegetable oil or a highly fermentable fibre source (beet pulp). Six Thoroughbreds age 3 years were fed one of 3 diets or 5 weeks in a replicated 3 x 3 Latin square.
