Abstract
El ganado Criollo de Puerto Rico es un recurso genético altamente adaptado a nuestras condiciones ambientales, pero probablemente en peligro de desaparecer. Por esta razón, diversos criadores y la Universidad de Puerto Rico, Recinto de Mayagüez se han unido como parte de un esfuerzo por preservar a estos animales, incluyendo la posibilidad de formar una asociación para el registro de esta raza. Para determinar cuáles animales deben ser registrados, primero es necesario caracterizar el fenotipo de esta raza. Este trabajo pretende establecer la base para la caracterización de su coloración. El ganado Criollo de Puerto Rico asume una coloración roja uniforme en todo el cuerpo, dentro de una gama de tonalidades posibles entre el rojo claro (bayo) y el rojo intenso (indio). Estos animales pueden presentar diferentes tonalidades de coloración negra en distintas partes del cuerpo incluyendo el morro, las pestañas, la piel, la borla, las patas, las pezuñas, la cara y los cuernos. Aunque poco frecuente, el ganado Criollo puede presentar manchas de color blanco, predominantemente de pequeño tamaño y localizadas en el área abdominal. También, en algunos machos puede observarse la incidencia de líneas negras en su pelaje (color gateado o “brindle”). Nuestro ganado Criollo puede asumir prácticamente cualquier combinación de estas coloraciones. La descripción de la coloración específica de cada parte del cuerpo puede usarse como una herramienta inicial para la identificación, caracterización y el posible registro de estos animales.

To determine which animals should be registered, it is first necessary to characterize the breed’s phenotype. This work aims to establish the basis for the characterization of their coloration. The Criollo cattle of Puerto Rico assume a uniform red coloration throughout the body, within a range of possible shades between light red (bayo) and intense red (indio). These animals can also have different shades of black coloration on different parts of the body including the snout, eyelashes, skin, tassel, legs, hooves, face and horns. Although rare, Criollo cattle may exhibit white spots, predominantly small in size and located on the abdominal area. In some males the incidence of black lines on their coat (crawled color or "brindle") can be observed. Our Criollo cattle can assume virtually any combination of these colors. A description of the specific coloration of each body part can be used as an initial tool for the identifying, characterizing and possibly registering these animals.
