The Pantaneiro cattle are descendant from animals brought by settlers in the beginning of the colonization of Brazil. Ten months old Pantaneiro steers, raised under pasture conditions in Brazil, were used to study puberty. Monhtly measurement of scrotal circumference and testicular width and length were recorded. Semen was collected by eletroejaculation and evaluated according to physical and morphological aspects. Penile and prepuce detachment percentages were also evaluated. The ages of first spermatozoa presence in the ejaculate, first motile spermatozoa in the ejaculate, seminal puberty and detachment between penis and prepuce was studied.
