Resumen

El presente trabajo tuvo como objetivo caracterizar fenotípicamente un rebaño de cabras azules, pertenecientes a la granja Carnaúba, municipio de Taperoá, Estado de Paraiba, Brasil, con el propósito de contribuir a la homologación del patrón racial en el Ministerio de Agricultura. Fueron evaluadas 62 hembras azules con edades a partir de dos años y peso medio de 40,3 kg, tomándose las siguientes medidas morfométricas: longitud corporal (71,5±5,6 cm), altura a la cruz (59,0±4,3 cm), perímetro torácico (76,9±4,8 cm), longitud de las orejas (12,6 cm), formato de los cuernos (bien implantados, simétricos, dirigidos hacia arriba, hacia detrás y hacia afuera, con pequeñas curvaturas hacia el frente en las extremidades y color ceniza oscuro). Los animales presentaron tres patrones distintos de capa: ceniza claro, ceniza azulado y ceniza azulado muy oscuro. Este estudio contribuirá al fortalecimiento de los trabajos de conservación de esta raza, que se encuentra en estado crítico debido a cruzamientos absorbentes e indiscriminados con otras razas exóticas.

Summary

This study aimed at the phenotypic characterization of a blue goat herd, on the Carnaúba farm, Taperoá Township, Paraiba State, Brazil, so as to support the development of a breed standard on behalf of the Ministry of Agriculture. In total, 62 two-year old females were evaluated with an average weight of 40.3 kg. Mean of morphometric measurements were body length (71.5±5.6 cm), hip height (59.0±4.3 cm) and chest perimeter (76.9±4.8 cm), ear length (12.6 cm). Horns are well implanted, symmetric, growing upwards, backwards and out, with small curvatures towards the front at the extremities and dark grey in colour. The animals had three distinct coat colours: light grey, bluish grey and very dark bluish grey. This study will contribute towards the strengthening of conservation works for this breed, which is in a critical state due to indiscriminate crossing with other exotic breeds.
