Abstract(s)
Sorraia horse is an endangered native primitive breed from Portugal, highly inbred with a small census of around
300 animals worldwide. The aim of the study was to present the difference between stance (St) and swing (Sw),
when the limbs are moving on the ground or in the air, respectively, during stride duration. Results were obtained
for the total, forelimbs and hindlimbs, left and right sides, and each limb separately. Using innovative technology
(EquiMoves), six Sorraia stallions were studied for the variables St and Sw (complete stride duration) at medium
Walk. The averages of the variables for a complete stride duration (1.16±0.10 s) were 0.70±0.08 s (St) and 0.46±0.02
(Sw), for the forelimbs, 0.72±0.09 s (St) and 0.44±0.03 (Sw), for hindlimbs 0.69±0.08 s (St) and 0.47±0.02 (Sw), for
the left side of 0.71±0.09 s (St) and 0.45±0.03 (Sw), and for the right side 0.70±0.07 s (St) and 0.46±0.02 (Sw). The
distribution by four limbs was, for left front 0.71±0.09 s (St) and 0.45±0.03 (Sw), right front 0.72±0.08 s (St) and
0.44±0.02 (Sw), left hind 0.69±0.08 s (St) and 0.47±0.02 (Sw) and right hind 0.68±0.06 s (St) and 0.48±0.01 (Sw).
Differences between variables St and Sw were significant (p-v<0.05), indicating that, on average, stride duration of
Sorraias stallions is distributed by 60.6% with the limb on the ground (St) and 39.4% with the limb in the air (Sw). On
the other hand, the differences within the variables were not significant (p-v>0.05) for the forelimbs, hindlimbs, both
sides and isolated limbs. The analysis of the medium Walk for variables St and Sw from Sorraia stallions, indicated
that, for a complete stride duration, limbs spend more time on the ground and present identical distribution among all
limbs. Sorraia horses are animals with a balanced and symmetrical distribution of the Walk. New studies, including
trot and canter, will allow to better understand the distribution of the variables St and Sw for Sorraia horse dynamics
and possible differences for the Walk.
