The “Saavedreño” Creole cattle was established at the Saavedra Experimental Station (Santa Cruz de la Sierra, Bolivia) in the seventies' aiming to obtain a dairy breed adapted to humid tropical environments. The relationship between the occurrence of the 1/29 translocation and subfertility or infertility is well known. On the other hand, the analysis of the Y chromosome morphology is useful to determine the possible introgression with Bos indicus. As the incidence of 1/29 translocation and Y-chromosome morphology has not been previously studied in the “Saavedrerio” Creole cattle, cytogenetic studies were performed in 40 bulls from different origin and 47 dams. Results obtained demonstrated a low frequency of 1/29 translocation (1.15%) in the animals and the presence of an acrocentric and submetacentric Y chromosome morphology.
