ABSTRACT
The macroscopic anatomy of the stomach in four adult dorcas gazelle was described. Four adult, two male and two female dorcas gazelle (Gazella dorcas) of the Frigya Zoological Park, Enfidha, Tunisie, were used in this study. The ruminal papillae were distributed unequally in the rumen, and were larger and more abundant within the atrium and in the two saccus cecus. The papillae were absent in dorsal part of the dorsal sac. The ruminal pillars had no papillae. The cellulae reticuli were divided and contained secondary and tertiary crests. The curvatura omasi measured 12.1±0.1 cm. A comparison with literature data for sand gazelles (Gazella subgutturosa marica) emphasises that differences between closely related species that fill similar niches cannot be expected to follow a clear pattern, but yield an inhomogenous picture, with some measurements more tending towards a specific feeding type in the one, and some other measurements tending more towards that feeding type in the other species.We concluded that the stomach morphology of the dorcas gazelle indicates the'cattle-type' morphophysiology representative for intermediate feeders.
RESUMEN
En este estudio se describe la anatomía macroscópica del estómago de cuatro gacelas dorcas adultas. Se utilizaron cuatro animales adultos, dos machos y dos hembras (Gazella dorcas) del Parque Zoológico Frigya, Enfidha, Túnez. Las papilas ruminales estaban distribuidas de manera desigual en el rumen, y se observaron de mayor tamaño y abundantes dentro de la aurícula, y en ambos saccus cecus. No se observaron papilas en la parte dorsal del saco dorsal. Los reticuli cellulae se dividieron y contenían crestas secundarias y terciarias. La curvatura omasi media 12,1±0,1 cm. Una comparación con los datos de la literatura en gacelas de arena (Gazella subgutturosa marica) indica que no se puede esperar un patrón exacto en las especies estrechamente relacionadas que llenan nichos similares, pero no cuentan con una imagen homogénea. En algunas de las mediciones se observa la tendencia hacia un tipo específico de alimentación en una especie, mientras que otras medidas tienden a asociar este tipo de alimentación a otras especies. La morfología del estómago de la gacela dorcas indica que la morfofisiologia de este tipo de ganado es representativa de alimentadores intermedios.
