Abstract
Description
En el siguiente trabajo se presentan los Índices de Rendimiento Económico
para Rheidae (Clase: Aves), los cuales incluyen los cálculos del Índice de
Utilidad General Modificado (Modified General Utility Index o MGUI) y de
los índices que lo componen: el Índice de Utilidad de Carne (Meat Utility
Index o MUI), Índice Medular (Marrow Index o MI), Índice General de Grasa
(White-Grease Index o WGI) y el Índice de Utilidad General (General Utility
Index o GUI). Se presenta además la metodología implementada para la
obtención de cada uno de los mismos y se discuten las implicancias de los
resultados a la luz de las expectativas generadas para los conjuntos
arqueofaunísticos. Los resultados obtenidos muestran valores netos de
rendimiento de carne, asociados a las partes anatómicas correspondientes al
esqueleto apendicular, así como altos índices de grasa en las porciones
axiales (cintura pélvica y esternón principalmente) y médula en tibiotarso
y tarsometatarso. Por último se analiza la correlación existente entre los
Índices de Rendimiento Económico y el Índice de Densidad Mineral Ósea, la
cual muestra un problema de equifinalidad.
In this paper, the Economic Indexes for Rheidae (Class Aves), which include the calculation of the Modified General Utility Index (MGUI) and its component indexes, Meat Utility Index (MUI), Marrow Index (MI), White Grease Index (WGI) and General Utility Index (GUI), are presented. Moreover, the methodology implemented for obtaining each index and the discussion of the results in an archeofaunistic setting are also presented. The results obtained show net values of meat performance associated with the anatomical portions belonging to the appendicular skeleton, as well as a high grease index in the axial portions (mainly pelvic girdle and sternum), and a high marrow index in tibiotarsus and tarsometatarsus. Finally, the correlation that exists between the Economic Utility Index and the Structural Bone Density Index is analyzed, showing a problem of equifinality.
