The aim of this study was to establish the growth curves in ovine Chiapas breed according to sex. Three models were used: logistic, von Bertalanffy and Gompertz. Body weight data were obtained from 66 males and 79 females of various ages. The three models showed similar goodness values; however, the logistic model was the best to describe the growth kinetics in this breed for both males and females, although this model tends to overestimate the initial body weights.

La morfometría es una herramienta para cuantificar y analizar la variación morfológica en el tamaño y forma de los animales. El objetivo del estudio fue contribuir a la caracterización morfométrica del cerdo criollo araucano para conocer algunas de sus características funcionales y etnológicas. Se estudiaron 58 cerdos (27 hembras y 31 machos), con edades entre 4 a 48 meses, localizados en tres veredas de Arauca, oriente de Colombia. Se obtuvieron 11 medidas corporales individuales y se construyeron tres índices. Se aplicó estadística descriptiva y un análisis univariado para medir el efecto ambiental sobre las medidas corporales e índices, usando la edad como covariable. Los cerdos presentaron una variabilidad media en las medidas corporales asociada con una mediana armonía. Los cerdos se consideran dolicocéfalos, mesolíneos y no aptitud cárnica. Las hembras tendían a s...
