An ex situ conservation program (CP) of Yacumeño cattle was established, in orderto obtain the animals for the CP, the original herd was fragmented. With the aim toevaluate the effect of the fragmentation on the mitochondrial diversity 28 sequencesof the D-loop mitochondrial of 14 individuals sampled in 1998 (original herd) and14 animals sampled in 2010 (fragmented herd) were analyzed. The results of thenucleotide diversity and the mean of pairwise differences in the Creole cattle were0.110 ± 0.073 and 1.757 ± 1.051 respectively. None of these estimations showedvalues higher than the animals sampled in the year 2010 (0.124 ± 0.083 and 1.978 ±1.188). The results show that no loss of mitochondrial diversity was detected due tothe split of the original herd. In addition, the study determined that the European(T3) and the African (T1) haplogroups are present in the Yacumeño herdrepresented by 11 haplotypes. One of them is unique to the Yacumeño Herd.
