This study aimed to (1) estimate infection prevalence of strongyle, Oxyuris equi and Parascaris equorum species and the intensity of infection with strongyles in working horses in lowland Lesotho and (2) investigate associations between infection and horse age, sex and owner-reported use of anthelmintics. In a cross-sectional survey, fresh faecal samples were obtained from 305 randomly selected horses and worm egg counts performed using a validated field laboratory kit. Details of anthelmintic use were collected using a standardised face-to-face owner questionnaire. Infection prevalence estimates for each species were calculated, as were infection intensity estimates for strongyle species. Logistic regression was used to investigate associations between exposure variables and infection status/intensity. Prevalence of strongyle infection was 88.2%; 11.8% of horses were not infected and infection intensity was low (1-500 eggs per gram (epg)) in 19.7%, medium (501-1,000 epg) in 19.7%) and high (>1,001 epg) in 48.8%. Decreasing strongyle infection intensity was associated with the use of proprietary equine anthelmintic products (OR 0.18, 95%CI 0.11-0.30, p<0.0001). Prevalence of O. equi infection was 6.2%; the odds of infection with this parasite decreased with increasing horse age (OR 0.84, 95%CI 0.72-0.97, p = 0.02). P. equorum infection prevalence was 21.6%; no statistically significant associations with the investigated exposure variables were found. In conclusion, strongyle infection is endemic in working horses in lowland Lesotho, but proprietary equine anthelmintics assist in managing infection. The apparent lack of age-acquired immunity to P. equorum infection may deserve further investigation. Although O. equi infection is less widespread, measures to protect younger animals may be appropriate.

SummaryReasons for performing study: To establish baseline parameters of equine health, owner knowledge and husbandry practices and tack against which benefits to local horses arising from an equine charity's training programme in Lesotho could be measured. Objectives: To describe and investigate associations between owner knowledge and equine husbandry practices, horse health and tack-related parameters prior to the start of the training programme. Methods: A cross-sectional survey was undertaken in the catchment area of students attending the first training course. Owners from randomly selected villages were interviewed about horse care using a standardised, structured questionnaire, administered face to face in local language. Horses were clinically examined and tack assessed according to standardised protocols. Results: Clinical examinations were performed on 312 horses and 287 owners were interviewed. Owners had variable knowledge of equine husbandry and limited understanding of appropriate primary and preventive healthcare. Equine health problems identified included ecto-and endoparasite infestation, mouth lesions, overgrown and unbalanced feet and tack-associated wounds. The majority of tack was in poor condition, dirty and ill-fitting. With the exception of below-average body condition score, no associations were found between key adverse horse-related clinical findings and owners reporting their horse as being 'unhealthy'. Conclusions: Working horses in Lesotho have a range of physical problems, many of which could be ameliorated through targeted owner education. With limited access to veterinary advice and scarce resources, improved availability of affordable local equine trade skills is key to improving equine health. Potential relevance: Findings could be used to inform and direct training programmes to maximise benefits to equine health and to serve as a baseline against which to monitor effects of educational and other interventions.

Bears rescued from the bile industry face a multitude of physical and psychological challenges. Many years of restricted movements and invasive treatment has left the majority of bears with reduced mobility. This article looks at the work done by the staff of Animals Asia’s Vietnam Bear Rescue Center to develop a physiotherapy program for the bears in their care
