The aim of this study was to evaluate the seminal characteristics and the physical and functional conditions of native and introduced sheep breeds under the environmental conditions of the Colombian Caribbean. In total, 117 Santa Inés, Dorper, Katahdin and Ovinos de Pelo Colombiano (OPC) rams older than 11 months were evaluated for 14 months. The animals were from 18 farms of the departments of Córdoba, Sucre, Bolívar, Cesar and La Guajira. The physical-functional examinations of the males were carried out, as well as the macroscopic and microscopic characteristics of the semen. There were no differences (p>0.05) between breeds, departments and collection methods for the variables testicular volume, testicular length and width, scrotal c...
