Certain breeds of horses may be genetically predisposed to developing insulin dysregulation, which is a risk factor for development of endocrinopathic laminitis in horses. This study was performed to test the hypotheses that Paso Fino horses exhibit evidence of insulin dysregulation compared with...

Colombian Paso horses have been classified into four categories based on gait performance: Colombian Paso Fino, Colombian Trocha, Colombian Trocha and Gallop, and Colombian Trot and Gallop. Selective breeding has led to the emergence of the Colombian Paso Fino as a distinct population. We describe...

This study aimed at describing selected hematological, biochemical, and acid-base variables of adult horses living at sea level and comparing them to those living at 5 different altitudes. One hundred and thirty-eight healthy Paso Fino horses > 2 years old were enrolled. Altitudes included the...

The Colombian paso horse, the most important horse breed in Colombia, performs specific and particular gaits (paso fino, trocha, and Colombian trot), which display different footfall patterns and stride frequencies. The breed has been selected for gait and conformation for more than 50 years and we ...

A unique eye color, called tiger-eye, segregates in the Puerto Rican Paso Fino (PRPF) horse breed and is characterized by a bright yellow, amber, or orange iris. Pedigree analysis identified a simple autosomal recessive mode of inheritance for this trait. A genome-wide association study (GWAS) with ...

Since the first Spanish settlers brought horses to America centuries ago, several local varieties and breeds have been established in the New World. These were generally a consequence of the admixture of the different breeds arriving from Europe. In some instances, local horses have been...

Urolithiasis is the presence of mineral concretions or urine crystals at the urinary tract. In horses, urolithiasis has a relatively low prevalence (0.4% to 0.5%), its presentation occurs at the level of the kidneys and the urinary bladder, the last one is the site of the greatest presentation....

The objective was to evaluate the effect of different freezing regimens on sperm function parameters and integrity in ejaculates from Colombian Paso Fino stallions. Five freezing extender formulations (1) skim milk-based extender+glycerol (SKM+GLY) (2) skim milk-based extender+N-N-dimethylformamide ...

The purpose of this study was to determine the daily follicular growth and the time in which ovulation will occur, in Paso Fino Colombian mares who were pastured at the Sabana de Bogotá Colombia in tropical conditions, with an altitude of 2.652 meters over sea level, average temperature of 12°C and ...
