Article Synopsis
- The study compared two different winter management strategies for Thoroughbred weanlings and yearlings in Hokkaido, Japan: one group was kept outdoors for 22 hours (22hr group), while the other group had 7 hours outdoors with 1 hour of exercise on a horse-walker (7hr+W group).
- Results showed that the 7hr+W group had similar daily travel distances as the 22hr group but exhibited better body weight gains, lower body temperature, and improved heart rate variability, indicating better overall metabolic health.
- Endocrine analysis revealed that the 7hr+W group had higher levels of prolactin and insulin-like growth factor, suggesting that this management strategy is more effective for
Article Synopsis
- The study examined radiographic changes in the forelimbs of foals over the first year of life, focusing on specific angles related to hoof and joint alignment.
- Key measurements showed significant increases in hoof angle and phalanx angles in the early weeks, indicating rapid developmental changes, while some angles decreased after reaching peak growth.
- The findings suggest that foals initially have a flexed fetlock and upright hoof alignment, transitioning to a mature conformation by six months, with physiological variations linked to common diseases in foals.
The effects of an extended photoperiod (EP) on body composition of Thoroughbreds colts and fillies from December at one year old to April at two years old were investigated. Seventy-three Thoroughbreds reared and trained in Hidaka Training and Research Center, Japan Racing Association, Hokkaido were used. Forty-one horses were under the EP conditions from December 20 to April 15, and the 32 horses were under natural light alone as the control group.

The horses were divided into two sex groups and reared and trained in Hidaka or Miyazaki for 7 months from October of one year of age to April of two years of age. Body weight (BW), rump fat thickness (RFT), fat-free mass (FFM), and percentage of fat (%F) were used as parameters of body composition.

However, in this study, we report a case of ICH in a 14-year-old boy with mild COVID-19 infection without pneumonia who had no such risk factors. The only abnormal laboratory finding was temporary depletion of vitamin K-dependent coagulation factors.
