This study aimed at establishing the morphological characteristics and morphometric indexes of Pêga donkeys, utilizing 47 animals, of which 22 were adults and 25 were growing donkeys. Prior to taking their measurements, the animals were restrained and made to stand squarely. The morphological data were measured, and the following morphometric indexes were determined body index (BI), meloscopic index (MI), dactylothoracic index (DTI), weight in cannon index (WCI), conformation index (CFI), and real live weight (RLW). The experimental design was subdivided into plots and repeated in time, in which the animals represented the plot and the data collection times were the subplots. No sex effect was noted for the morphological measurements and morphometric indexes of growing donkeys. The effect of growth period was observed for all the variables. At birth, donkeys weighed around 14.86% of the weight of dams, and at six months they reached up to 40.37%. For the height taken at the withers, the animals at birth were 67.77% of the height of dams, and at six months they achieved up to 84.45%. Based on the morphometric indexes, it is suggested that adult and growing Pêga donkeys can be classified as being suited for both saddle and draft activities and possess a higher load capacity when compared with horses. A few indexes including BI, MI, and RLW need to be adjusted to be suitably used in rating the donkeys.(AU)
