SALAS-CASTILLO, Gaby Beatrice. Croup Conformation and Caslick's index in Peruvian Paso Mares. Rev. Med. Vet. [online]. 2022, n.44, pp.41-46.  Epub May 26, 2022. ISSN 0122-9354.  https://doi.org/10.19052/mv.vol1.iss44.6.

This study aims to determine the Caslick's Index in Peruvian Paso mares and how it relates to the croup conformation (croup inclination angle and type of tail insertion). To find the Caslick's Index, croup inclination, and tail insertion, some morphometric measures were made in the mares that participated in the LXX Official National Contest of Peruvian Paso Horses (n = 98). The mean for the croup inclination angle was 37.3° + 4.88°. Most of the mares showed a high tail insertion (55.1 %), and the average mean Caslick's Index was 42.68 + 35.05. More than 90% of the mares had a good vulvar conformation. It was concluded that there was no relationship between the tail insertion and the Caslick's Index (p > 0.05), nor any correlation between age and croup inclination vs. Caslick's Index (ρ = -0.187 and 0.042, respectively; p > 0.05). However, a negative correlation was found between the number of labors and the Caslick's Index (ρ = -0.264; p < 0.05).
