Common clinical findings identified in working equids in low- and middle-income countries from 2005 to 2021.

Abstract: Despite several millions of working equids worldwide, there are few published studies regarding the epidemiology of their health and welfare. Data collected by non-governmental organisations (NGOs) operating in the working equid sphere therefore have important epidemiological value and could be used towards animal health surveillance. The aim of this study was to identify common clinical findings and mortality patterns of working equids in low- and middle-income countries and investigate their epidemiology using data collected from an international NGO. A retrospective analysis was conducted to determine the proportion of clinical findings and mortality risk by equid species, year and region. Negative binomial regression models were generated to investigate differences in mortality risk and proportion of key clinical findings between equid species, hemispheres and calendar month. A total of 4,313,606 presentations were reported from 14 countries between January 2005 and March 2021 (mean 22,121; SD ± 7,858 per month). Wounds and abscesses were the most reported clinical finding for all equid species (mean proportion 35%; SD ±0.19 of all findings). A higher proportion of wounds (mean proportion 41.7%; SD±0.2) was recorded in donkeys than mules or horses (P<0.001). Mules had higher reported mortality risk (1.2%; 95% CI 0.94-1.46%) than horses (0.4%; 95% CI 0.36-0.55%; p<0.001) or donkeys (0.2%; 95% CI 0.14-0.22%). Work-related wounds were the predominant finding in working equids, particularly so in donkeys. Prevention strategies should focus on improvements to work equipment and practices for all equids. Future investigations required include refinement of diagnostic approaches for donkeys and investigation of risk factors to understand the higher mortality in mules. Routine monitoring of clinical findings reported by national or international NGOs could be included in animal health surveillance strategies, although standardisation of data for this purpose is needed so that changes in prevalence following implementation of prevention strategies can be monitored.

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.

This research study explores the common health concerns and death risks of working equids (donkeys, mules, and horses) in low- and middle-income countries. The data comes from non-governmental organizations and reveals that work-related wounds are a significant issue, with the highest proportion noted in donkeys.

Objective and Methodology

  • The objective of this study was to understand the prevalent health issues and mortality patterns seen in working equids (donkeys, mules, and horses) found in low and middle-income nations, using the data gathered by a global non-governmental organization (NGO).
  • To achieve this research goal, the scholars conducted a retrospective analysis, determining the proportion of clinical findings and evaluating the risk of mortality according to the equid species, the year and the region.
  • In their analysis, the researchers used negative binomial regression models to investigate the difference in mortality risk and proportion of essential clinical findings based on equid species, geographical hemisphere, and calendar month.

Findings

  • The researchers utilized a total of 4,313,606 presentations reported from 14 nations between January 2005 and March 2021.
  • The most reported clinical finding for all species of equids were wounds and abscesses, comprising an average of 35% of all findings.
  • A higher proportion of wounds – roughly 41.7% – was recorded in donkeys, significantly higher than the number reported in mules or horses.
  • Mules were revealed to have a higher documented mortality risk at 1.2% compared to horses at 0.4% and donkeys at 0.2%.
  • Work-related injuries were identified as the predominant clinical health issue, especially in donkeys.

Recommendations

  • Prevention approaches should pay special attention to improving work equipment and practices for all equids to reduce the occurrence of work-related wounds.
  • Further investigations are necessary to improve diagnostic methods for donkeys and to comprehend the factors contributing to the higher mortality risk in mules.
  • Regular monitoring of clinical findings by national or international NGOs could be incorporated into animal health surveillance strategies, but data standardization is required to track any prevalence changes after implementing preventative strategies.
