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.

The morphometry is a tool to quantify and analyze morphological variation in the size and shape of animals. The aim of this study was to contribute to the morphometric characterization of the Araucanian creole pig to know some of its functional and ethnological characteristics. For this. 58 pigs (27 females and 31 males), aged between 4 and 48 months, located in three villages of Arauca, eastern Colombia, were studied. Eleven individual body measurements were obtained, and three indices were constructed. Descriptive statistics and univariate analysis were applied to measure the environmental effect on body measurements and indices, using age as a covariate. The pigs showed a medium variability in body measurements associated with a medium harmony. These animals are considered to be dolichocephalic, mesolineal and not suitable for meat purposes. The females tended to be larger than the ma...
