Abstract: The aim of this study was to conduct a series of paper-based exercises in order to assess the negative (adverse) welfare impacts, if any, of common interventions on domestic horses across a broad range of different contexts of equine care and training. An international panel (with professional expertise in psychology, equitation science, veterinary science, education, welfare, equestrian coaching, advocacy, and community engagement; = 16) met over a four-day period to define and assess these interventions, using an adaptation of the domain-based assessment model. The interventions were considered within 14 contexts: C1 Weaning; C2 Diet; C3 Housing; C4 Foundation training; C5 Ill-health and veterinary interventions (chiefly medical); C6 Ill-health and veterinary interventions (chiefly surgical); C7 Elective procedures; C8 Care procedures; C9 Restraint for management procedures; C10 Road transport; C11 Activity-competition; C12 Activity-work; C13 Activity-breeding females; and C14 Activity-breeding males. Scores on a 1-10 scale for Domain 5 (the mental domain) gathered during the workshop were compared with overall impact scores on a 1-10 scale assigned by the same panellists individually before the workshop. The most severe (median and interquartile range, IQR) impacts within each context were identified during the workshop as: C1 abrupt, individual weaning (10 IQR 1); C2 feeding 100% low-energy concentrate (8 IQR 2.5); C3 indoor tie stalls with no social contact (9 IQR 1.5); C4 both (i) dropping horse with ropes (9 IQR 0.5) and forced flexion (9 IQR 0.5); C5 long-term curative medical treatments (8 IQR 3); C6 major deep intracavity surgery (8.5 IQR 1); C7 castration without veterinary supervision (10 IQR 1); C8 both (i) tongue ties (8 IQR 2.5) and (ii) restrictive nosebands (8 IQR 2.5); C9 ear twitch (8 IQR 1); C10 both (i) individual transport (7.00 IQR 1.5) and group transport with unfamiliar companions (7 IQR 1.5); C11 both (i) jumps racing (8 IQR 2.5) and Western performance (8 IQR 1.5); C12 carriage and haulage work (6 IQR 1.5); C13 wet nurse during transition between foals (7.5 IQR 3.75); and C14 teaser horse (7 IQR 8). Associations between pre-workshop and workshop scores were high, but some rankings changed after workshop participation, particularly relating to breeding practices. Domain 1 had the weakest association with Domain 5. The current article discusses the use of the domain-based model in equine welfare assessment, and offers a series of assumptions within each context that future users of the same approach may make when assessing animal welfare under the categories reported here. It also discusses some limitations in the framework that was used to apply the model.

This research study used a specialist panel to assess the negative impact of common domestic horse practices on their welfare. The aspects studied included veterinary treatment, equine handling, and care tactics. The intent was to determine any harmful effects these practices have on horses and to provide insights for better welfare practices.
Five Domains Model
The research employed the use of the Five Domains Model, a tool that assesses animal welfare by evaluating physical and mental states. These domains include nutrition, physical environment, health, behavioural interactions, and psychological, labelled as Domain 1 through 5, respectively.
The model was used to analyze the impacts of various common interventions on horse welfare. These were considered across 14 different horse care and training contexts.
Procedures and Evaluation
The panelists scored the impacts of these interventions on a scale of 1-10, with 10 being the most severe impact on Domain 5, which evaluates the horse’s mental state.
The panel met over four days for the assessment and definition of the various interventions, discussing and ranking each in terms of their negative effect on the welfare of the horses.
Findings
The research identified the most severe negative impacts within each context, with some practices such as abrupt, individual weaning and indoor tie stalls with no social contact scoring notably high.
Other practices like feeding 100% low-energy concentrate and major deep intracavity surgery also scored high, indicating a significant adverse welfare impact.
Practices associated with breeding, like using a horse as a wet nurse during the transition between foals and using a teaser horse, presented less severe, but nonetheless significant, welfare impacts.
The scores for Domain 5 showed a strong correlation with the overall impact scores assigned by the panelists before the workshop, thus implying a consistent perception of welfare impacts among the experts.
Limitations and Future Use
The Domain 1, nutrition, had the weakest association with Domain 5, suggesting the need for more precise evaluation in this aspect.
The paper provided a series of assumptions for each context that future practitioners can refer to when using the same welfare assessment technique.
The research also highlighted limitations in the framework employed to apply the model. These limitations will be beneficial in refining the assessment process for future studies.
