Morfometría del cerdo criollo del Pacifico Colombiano

In order to characterize morphologically the creole pig population from the Colombian Pacific region, a random sample of 83 pigs over 8 months of age from Choco, Cauca y Narino was obtained. In the Pacific of Valle del Cauca creole pigs were not found. Using tools like hipometer, metric tape and compass, and with direct observation, 14 morphological measurements, five zoometric indices and 10 qualitative variables were determined. Creole pigs from Narino showed higher values in 11 of 14 variables were obtained. Morphological measurements and zoometric indices were analyzed with descriptive statistic and analysis of variance, and with quantitative variables, a principal component analysis was made. Qualitative variables were analyzed by frequencies. A canonical discriminant analysis for cuantitative and qualitative variables was made. Choco creole pigs are brevilineal, Narino creole pigs are mesolineal and Cauca creole pigs are longuilineal. In Choco are dolichocephalic and dominates the heights off the body length. In Cauca and Narino are mesocephalic and body form is similar to a rectangle. Qualitatively subconcavilineal profile, the cloven hoof, an average of 12 nipples and celtic ear were dominant, although in Cauca was presented in the same proportion as the Iberian type. The coat color in pigs of Choco was mostly black, in Cauca blond with black spots and Narino black piebaldism predominated. Two distinct groups was determined: one corresponding to creole pigs from afro descendant communities of Choco, living in warm weather conditions, rainy intertropical and another consisting of creole pigs of indigenous communities of Cauca and Narino, linving in proximity to the mountains, in temperate and cold climate, which shows a clear morphological adaptation of the climatic environment the region where are the animals.
