Bodyweights And Growth Rates Of Spring- And Autumn-born Thoroughbred Horses Raised On Pasture
AIM: To examine the growth of spring- and autumn-born Thoroughbred foals raised on pasture.
The Pituitary And Testicular Responses To Gnrh Challenge Between 4 And 14 Months Of Age In Thoroughbred Colts Born In Spring And Autumn
Gonadotropin releasing-hormone analogue (buserelin) challenges were carried out every 8 weeks from 4 to 14 months of age on thoroughbred colts born in the spring (n = 6) or autumn (n = 5) to define the onset of puberty.
The Effect Of Varying Dietary Starch And Fat Content On Serum Creatine Kinase Activity And Substrate Availability In Equine Polysaccharide Storage Myopathy
The effect of dietary starch and fat content on serum creatine kinase (CK) activity and substrate availability was evaluated in 4 mares of Quarter Horse-related breeds with polysaccharide storage myopathy (PSSM).
Antioxidant Supplementation And Subsequent Oxidative Stress Of Horses During An 80-km Endurance Race
This study tested the development of oxidative stress and the effects of antioxidant supplementation in an 80-km ride. A precompetition survey revealed that no competitor would participate without vitamin E supplementation; therefore, 46 horses were paired for past performances and randomly assigned to two groups of 23 each for 3 wk of supplementation before the ride.

Onset Of Puberty In Pasture-raised Thoroughbreds Born In Southern Hemisphere Spring And Autumn
OBJECTIVES: To examine the age, bodyweight and date of onset of puberty in Thoroughbreds born in spring and autumn.
LH And Testosterone Responses To Five Doses Of A GnRH Analogue (Buserelin Acetate) In 12-month-old Thoroughbred Colts
To determine the responsiveness of the pituitary–gonadal axis of peri-pubertal colts to GnRH, buserelin (0.5, 1, 5, 10 and 40 μg) was given to 13 male Thoroughbred yearlings (n=3–8 colts per dose).
Comparison Of Volumetric Urine Collection Versus Single-sample Urine Collection In Horses Consuming Diets Varying In Cation-anion Balance.
To determine daily variation in urinary clearance and fractional excretion (FE) of electrolytes and minerals within and between horses and to compare volumetric and single-sample urine collection for determining FE values of diets with a range of dietary cation-anion balance (DCAB).
Effect Of Dietary Starch, Fat, And Bicarbonate Content On Exercise Responses And Serum Creatine Kinase Activity In Equine Recurrent Exertional Rhabdomyolysis
To determine the effect of dietary starch, bicarbonate, and fat content on metabolic responses and serum creatine kinase (CK) activity in exercising Thoroughbreds with recurrent exertional rhabdomyolysis (RER), 5 RER horses were fed 3 isocaloric diets (28.8 Mcal/d [120.5 MJ/d]) for 3 weeks in a crossover design and exercised for 30 minutes on a treadmill 5 days/wk.
Comparison Of The Metabolic Responses Of Trained Arabian And Thoroughbred Horses During Low And High Intensity Exercise
he metabolic responses to low and high intensity exercise were compared in 5
Arabian (AR) and 5 Thoroughbred (Tb) horses. The higher aerobic and anaerobic capacity of the Tb horses likely contributed to their superior high intensity exercise performance. Conversely, the AR may be better adapted for
endurance exercise as evidenced by the greater use of fat. These metabolic differences may reflect breed variation in muscle fiber types.
