Abstract: El Caballo Peruano de Paso tiene un valor histórico y cultural en nuestro
país. Es una raza originada por el cruce de las razas de caballos Árabes, Berberisco
y Andaluz, los cuales llegaron con los españoles durante la conquista. El interés en
su crianza permitió la creación de la Asociación Nacional de Criadores y
Propietarios del Caballo Peruano de Paso en 1947, desde entonces la asociación
realiza el registro genealógico de ejemplares de esta raza en todo el país. Sin
embargo, no existen referencias actuales sobre la caracterización genética de la
raza, ni de la variabilidad genética que presenta la población del Caballo Peruano
de Paso en Perú. El objetivo del presente estudio fue analizar el registro
genealógico del Caballo Peruano de Paso y estimar los parámetros poblacionales.
La base de datos empleada en el presente estudio comprende la genealogía de
5923 animales vivos registrados, pertenecientes a 53 criadores a nivel nacional. Se
tuvo el registro de 11213 animales desde el año 1938 al 2022. Se emplearon los
programas Pedigree Viewer y ENDOG v4.8 para preparar la base de datos y
elaborar el árbol genealógico, identificar a los ejemplares con mayor número de
crías, determinar la integridad del pedigrí, estimar el coeficiente de consanguinidad
promedio y por generación, y el tamaño efectivo de la población. Se han identificado
a 15 reproductores que en total tuvieron 1850 crías, y que 13 de ellos estan
emparentados con el caballo PN-00017 (AV. Sol de Paiján). Además, se ha
observado que contamos con el registro de más del 94% de los padres, 88% de los
abuelos y 85% de los bisabuelos de los 11213 animales del registro empleado en
el presente estudio. El coeficiente de consanguinidad promedio estimado fue de
6.48% y el tamaño efectivo de la población fue de 40.3 animales. Los resultados
obtenidos indican la perdida de variabilidad genética dentro de la población de
Caballo Peruano de Paso empleada en el presente estudio, ello como efecto de los
apareamientos consanguíneos realizados dentro de esta raza con el fin de fijar
caracteres fenotípicos de interés para los criadores
The Peruvian Paso Horse has a historical and cultural value in our country. This breed was established through the crossing of the Arabian, Berberisco and Andalusian horse breeds, which were brough by the Spanish during the invasion. The interest on this breed allowed the establishment of the National Association of Breeders and Owners of the Peruvian Paso Horse in 1947, since then the association has carried out the pedigree registration of all horses and mares of this breed throughout the country. However, there are no current information about the genetic characterization and the genetic variability of this breed in Peru. The aim of this research was to analyze the pedigree record of the Peruvian Paso Horse and estimate the population parameters. The database used included the pedigree of 5923 alive horses, belonging to 53 breeders nationwide. The whole database contained the record of 11,213 animals from 1938 to 2022. The Pedigree Viewer and ENDOG v4.8 softwares were used to prepare the database and make the family tree, identify the stallions with the largest number of offspring, determine the integrity of the pedigree, estimate the average inbreeding coefficient and per generation, and the effective population size. 15 stallions had a total of 1850 offspring, and 13 of them are related to the horse PN-00017 (Sol de Paijan av.). Furthermore, our results showed that the 94% of the parents, 88% of the grandparents and 85% of the great grandparents of the 11,213 animals in the pedigree used are known. The estimated average inbreeding coefficient was 6.48% and the effective population size was 40.3 animals. The results indicate the loss of genetic variability within the population of Peruvian Paso Horse used in this research, as an effect of inbreeding mating carried out within this breed to establish the main phenotypic traits in this breed
