Inspiratory and expiratory tracheal pressures during high‐intensity exercise in harness racehorses
Equine Veterinary Journal, EarlyView.Abstract Background Exercise‐related upper respiratory tract (URT) disorders are common in racehorses. Objective assessment of URT mechanics is essential to quantify degrees of obstruction caused by URT disorders identified upon dynamic endoscopy. Objectives To establish reference values for inspiratory and expiratory tracheal pressures (cmH2O) during ...

Abnormal cleavage patterns in equine in vitro‐produced embryos lead to higher early pregnancy loss
Equine Veterinary Journal, EarlyView.Summary Background Despite significant advances, in vitro production (IVP) of equine embryos continues to lack standardised embryo classification criteria and is associated with increased rates of early pregnancy loss compared with in vivo‐derived blastocysts.

Equine Veterinary Journal, EarlyView.Abstract Background Radiographic protocols for the metacarpo‐/tarsophalangeal joint during pre‐purchase examinations (PPE) vary internationally, but their impact on pathology detection remains unclear. Optimising imaging protocols is essential to balance diagnostic accuracy with workflow efficiency and radiation exposure.

Equine Veterinary Journal, EarlyView.Abstract Background There are limited data on long‐term follow‐up of radiographic changes of the proximal sesamoid bones (PSBs) in Thoroughbred racehorses. The effect of training and racing on radiodensity of the PSBs in live Thoroughbreds has not been described.
