“…Holmström et al [18] studied the conformational characteristics of elite sport horses and found that elite dressage horses had more sloping shoulders and Holmström and Philipson [19] showed a positive correlation between good gaits and sloping shoulders in warm blood horses. It could then be thought that the inclination of this region with respect to the horizontal plane influences the quality of movement in the fore limb.…”

Walk and trot in the horse at driving: kinematic adaptation of its natural gaits

et al. 2006

-The walk and trot at hand and at driving of five Andalusian Purebred stallions were studied by a 2D semiautomatic analysis system. Linear, temporal and angular variables from the right fore and hind limbs were obtained by using a 2D kinematic analysis system. In order to identify significant differences between handled and driving gaits, a paired Student t-test was performed. The swing period and the stride lengths of both fore and hind limbs and the overreach distance were lower at driving. Stride durations and Retraction-Protraction angle values in the hind limbs at trot did not differ under different conditions but scapular values at walk and trot, fore fetlock variables at trot and some of the stifle and tarsus parameters at walk and trot were modified by the use of the vehicle. It may be assumed that at fixed speeds driving horses try to maintain the stride duration of their natural gaits.

“…Breeding aims of most modern Warmblood horse breeds are focused on performance, particularly on performance in riding sports [17]. Several, but not all genetic studies on this topic have shown the relation between particular conformation traits and performance in equestrian sports [11,12,21,22]. Evaluation of and selection for functional conformation is therefore used as a tool for indirect performance selection.…”

-Studbook inspection (SBI) data of 20 768German Warmblood mares and radiography results (RR) data of 5102 Hanoverian Warmblood horses were used for genetic correlation analyses. The scores on a scale from 0 to 10 were given for conformation and basic quality of gaits, resulting in 14 SBI traits which were used for the correlation analyses. The radiographic findings considered included osseous fragments in fetlock (OFF) and hock joints (OFH), deforming arthropathy in hock joints (DAH) and distinct radiographic findings in the navicular bones (DNB) which were analyzed as binary traits, and radiographic appearance of the navicular bones (RNB) which was analyzed as a quasi-linear trait. Genetic parameters were estimated multivariately in linear animal models with REML using information on 24 448 horses with SBI and/or RR records. The ranges of heritability estimates were h 2 = 0.14−0.34 for the RR traits and h 2 = 0.09−0.50 for the SBI traits. Negative additive genetic correlations of r g = −0.19 to −0.56 were estimated between OFF and conformation of front and hind limbs and walk at hand, and between DNB and hind limb conformation. There were indications of negative additive genetic correlations between DAH and all SBI traits, but because of low prevalence and low heritability of DAH, these results require further scrutiny. Positive additive genetic correlations of r g = 0.37−0.52 were estimated between OFF and withers height and between OFH and withers height, indicating that selection for taller horses will increase disposition to develop OFF and OFH. Selection of broodmares with regards to functional conformation will assist, but cannot replace possible selection against radiographic findings in the limbs of young Warmblood riding horses, particularly with regards to OFF. riding horse / conformation / studbook inspection / radiographic finding / additive genetic correlation

SUMMARYIn the present study a description of some basic conformational and biokinematic characteristics of 16 mares that belong to the breed Caballo Fino Chilote was conduce, at the hand-led walk. The objective was to determine some conformational and biokinematic characteristics at the hand led walk for 16 mares and the possible aptitudes, of this breed, for being used as a therapeutic tool in hipotherapy activities. The conformational parameters were measured in vivo using a metric tape and ruler. For the time-related and biokinematic parameters, a 10m curtain graduated every 50 cm was specially made, in front of which each mare was guided at a hand-led walk while being filmed with a Sony Hi-8 camera. The video was transformed into photos using the Final Cut programme; 15 frames per second were obtained in JPG format; the frames were then passed into TIFF to measure the angular parameters with the help of the Scion Image programme. Lineal parameters were directly measured from the video using a Sony flat screen television. All data analysis was conducted with descriptive statistics using Microsoft Excel xp. The means obtained for conformational parameters were: height at the withers 117.94 cm (± 2.6), height at the back 113.3 cm (± 2.1), and height at the hindquarters 119.9 cm (± 3.1). For the lineal parameters the mean stride length was 135.3 cm (± 8.9) and the mean step length was 69.3 cm (± 5.8). The mean stride duration was 1.18 seconds giving a mean speed of 114.7 cm/sec. The angular parameters of the limbs were measured for the shoulder, elbow and carpus joints in the forelimb and for the hip, stifle and tarsus joints in the hindlimb, also the scapula and pelvis inclination were measured obtaining curves for each one along a complete stride cycle, and angular range of motion was determined.Palabras clave: caballo chilote, biocinemática, videografía, hipoterapia.
