Abstract

The impact of head and neck position (HNP) on horse welfare has received much attention in the scientific literature within the last two decades. Studies have identified physiological and behavioural signs of distress in horses ridden for prolonged time in a HNP with their noseline behind the vertical (BTV), which may compromise their welfare. The objective of this study was to compare potential differences of HNPs shown in horse sales photographs advertised in an Australian horse sales magazine (Horse Deals) from the years 2005 and 2018. Additionally, factors potentially impacting HNPs, such as type of tack presented in (e.g. noseband type), riding discipline, competition experience of the horse, were investigated. The sample population (n=570) comprised horses ridden with headgear and bit in walk, trot, or canter/gallop, advertised in an Australian horse sales magazine. Issues from April 2005 and October/November 2018 were selected. HNP was categorised as behind the vertical (BTV), on the vertical (OV), slightly in front of the vertical (IFV), or extremely in front of the vertical (EIFV) (any HNP >30˚ IFV). Data were analysed using Chi-squared test and post-hoc testing via a multiple regression approach through SPSS, and test of proportions via the z-score calculator for two independent population proportions. Analysis of combined data from years 2005 and 2018 showed 47.0% (n=570) of the horse sample population were advertised with HNPs BTV. BTV HNP was observed as the predominant HNP (57.8%) (n=268), in the warmblood/eventers/show/performance (WESP) category (p<0.0005). In 2005, 53.4% (n=303) of the sample population were ridden BTV compared to 39.7% (n=267) in 2018 (p<0.001), 12.9% (n=303) were OV in 2005 compared to 15.0% (n=267) in 2018 (p>0.05), and 10.9% (n=303) were IFV in 2005 compared to 27.3% in 2018 (n=267) (p<0.0004). These results suggest a positive development with less vendors/riders selecting images where the horse’s nose was BTV. However, this may be explained by the larger proportion of horses advertised in the WESP category in 2005 (63.0%) (n=303) vs. 2018 (28.5%) (n=267), and the WESP category predominantly comprised of dressage, jumper, and eventing horses. In addition, the reduction of HNPs BTV from 53.4% (n=303) in 2005 to 39.7% (n=267) in 2018 could be attributed to the observation that in 2018, a larger proportion of horses were listed in categories that do not require the horses to be worked with a flexed HNP referred to as ‘on-the-bit’ (e.g. Western, Endurance, Australian Stock Horses). The HNP BTV remains preferential by a substantial proportion of the horse owning public when advertising horses for sale, particularly in disciplines where the horse is worked in a flexed HNP or ‘on-the-bit’.
