Indicators of productive efficiency of an experimental module of chinchillas and comparisons with commercial systems
In a small-scale chinchilla intensive production system, managed on the basis of an experimental protocol with artificial control of the photoperiod, 24 productive-reproductive indicators were surveyed for three consecutive years. The values of all indicators were similar or higher than those report...

In a small-scale chinchilla intensive production system, managed on the basis of an experimental protocol with artificial control of the photoperiod, 24 productive-reproductive indicators were surveyed for three consecutive years. The values of all indicators were similar or higher than those reported in the literature in different production systems. This can be explained by: (1) the average fertility maintained during the period studied, generated in part by the annual systematic scrap of all females without registered birth, regardless of their skin phenotype; (2) the size of litter at birth and weaning, which although showed values within the range of bibliographic reference, were accompanied by an acceptable percentage of total mortality, and (3) births per reproductive female per year and per mother per year above most of the data referenced in the literature, attributable to the stimulation determined by photoperiodic management. The values reported in the Experimental Module surpassed in one kitten weaned per mother and per year, the enterprises dedicated to the production of chinchillas of the area of influence of the FCV-UNR. En un sistema de producción intensivo de chinchillas, de pequeña escala, manejado en base a un protocolo experimental con control artificial del fotoperíodo se relevaron durante tres años consecutivos 24 indicadores productivo-reproductivos. Los valores de todos los indicadores fueron similares o superiores a los informados en la bibliografía en diferentes sistemas productivos. Ello puede explicarse por: la fertilidad promedio mantenida durante el período estudiado, generada en parte por el refugo sistemático anual de toda hembra sin parto registrado, independientemente de su fenotipo peletero; el tamaño de la camada al nacimiento y al destete, que si bien mostraron valores dentro del rango de referencia bibliográfica, estuvieron acompañados por un porcentaje de mortalidad total satisfactorio y partos por reproductora por año y por madre por año por encima de la mayor parte de los datos referenciados en la bibliografía atribuibles a la estimulación determinada por el manejo fotoperiódico. La conjunción de estos indicadores permitió alcanzar valores de 2,31 y 2,85 gazapos destetados por reproductora y por madre por año. Los valores informados en el Módulo experimental superan en un gazapo destetado por madre y por año a los emprendimientos dedicados a la producción de chinchillas del área de influencia de la FCV-UNR.
