The Effect of Season and Breed on Hypothalamic-Pituitary-Adrenal Axis Hormones, Metabolic Hormones, and Oxidative Markers in Ponies and Horses.

Background: Endocrine function in ponies differs from horses, with seasonally increased concentrations of plasma adrenocorticotropic hormone (ACTH) and an increased risk of insulin dysregulation.

Hypothesis: (1) Season and breed differences exist in concentrations of hypothalamic-pituitary-adrenal axis and metabolic hormones; and (2) systemic oxidative status is significantly different between ponies and horses and correlates with endocrine hormones.

Animals: Thirty-four healthy Welsh ponies and 14 healthy Quarter horses.

Post-anesthetic CPS and EQUUS-FAP scores in surgical and non-surgical equine patients: an observational study.

Background: Equine pain scoring may be affected by the residual effect of anesthetic drugs.

Objectives: To compare pain scores in the hours immediately following anesthetic recovery to baseline pre-anesthetic scores in equine patients undergoing surgical and non-surgical procedures.

Study Design: Clinical observational study.
