Recumbency as an Equine Welfare Indicator in Geriatric Horses and Horses with Chronic Orthopaedic Disease.

Abstract: Recumbency is a prerequisite for horses achieving rapid eye movement (REM) sleep and completing a full sleep cycle. An inability to lie down due to environmental insecurities or pain results in REM sleep deficiency, which can cause substantial impairment of welfare and health. Therefore, the present study used wearable automated sensor technology on 83 horses housed in an animal sanctuary to measure and compare the recumbency, locomotion, and standing time budgets of geriatric horses with and without chronic lameness to younger adult sound and lame horses. Recumbency times ranged from 0 to 319 min per day with an overall mean of 67.4 (±61.9) minutes; the time budget for locomotion was 19.1% (±11.2% s.d.) and for standing 75.6% (±13.1 s.d.). Interestingly, neither age nor lameness due to chronic orthopedic disease had a significant influence on recumbency times in this study. Eight horses showed symptoms of REM deficit. These horses had significantly shorter lying times (7.99 ± 11.4 min) and smaller locomotion time budgets than the other horses enrolled in this study (73.8 ± 61.8 min), indicating a general compromise of well-being. Thus, wearable sensor technology can be used to identify horses with low recumbency times at risk for REM sleep deficiency and to assess and monitor equine welfare objectively.

Summary

This research summary has been generated with artificial intelligence and may contain errors and omissions. Refer to the original study to confirm details provided. Submit correction.

The research paper explores the use of wearable automated sensor technology to measure and compare the recumbency, locomotion, and standing time budgets of geriatric horses and adult horses with and without chronic lameness, and its relation to equine welfare.

Recumbency and Equine Welfare

  • The study begins by stating the importance of recumbency, which is the ability to lie down, for horses. It’s foundational for horses to complete their rapid eye movement (REM) sleep cycle.
  • A lack of REM sleep, caused by an inability to achieve recumbency due to pain or environmental insecurity, can substantially impair a horse’s health and welfare.

Experimental Set-up

  • The paper uses automated wearable sensor technology to monitor recumbency and locomotion in horses.
  • The researchers examined 83 horses housed in an animal sanctuary. The cohort comprised of geriatric horses as well as younger adults, both sound and those affected by chronic lameness.

Study Findings

  • The investigators found a range of recumbency times, between 0 to 319 minutes per day. The mean recumbency time was about 67.4 minutes.
  • The time spent on locomotion was around 19.1% and for standing was approximately 75.6%.
  • Surprisingly, age or chronic lameness did not significantly affect the recumbency times of the horses under study.

Special Case Findings

  • The researchers noted eight horses that showed symptoms of REM deficit. These horses registered significantly shorter lying times (about 8 minutes) and smaller locomotion time budgets compared to the others (approximately 74 minutes).
  • This significant decrease in recumbency time and locomotion budget indicates an overall compromise in the well-being of these horses.

Conclusions and Implications

  • The study concludes that wearable sensor technology can be used to identify horses with low recumbency times, who are at risk for REM sleep deficiency.
  • This detection aid can then be used to objectively assess and improve equine welfare, as it provides a practical indicator of health and well-being in horses.
