The cattles is the most important livestock as a source of meat, milk, labor and other needs.
Cattles productivity in Indonesia is still low compared with other countries, but actually still can
be improved through environmental modification or change its genetic quality. Bali’s cattle is
one of the potential of local beef cattle type of potential and suitable to be developed in the field
conditions in Indonesia in general.
The purpose of this study was to determine genetic variation and phylogenetic relationships of
the cattle Bali-Bali and Bali-Lombok on variations of the cytochrome b gene of mitochondrial
DNA. The benefits of this research is to provide scientific information of the genetic diversity
and phylogenetic Bali’s cattle in Bali and Lombok compared with the ancestor Banteng (Bos
javanicus) based on cytochrome b mitochondrial gene.
This study is a descriptive study, using the cytochrome b as a marker. This research data is

sequencing results that analized using MEGA (Molecular Evolution Genetic Analyzis) software
version 4.
The results of this study indicate that the highest variation found in cattle that is as much as 8
Lombok 83 nucleotides, whereas the lowest variation present in Bali cattle as many as 7 of 12
nucleotides. Phylogenetic tree shows that genetically, Bali’s cattle population of Bali and
Lombok areas can be grouped into 7 major groups. the closest genetic distance between BaliLombok beef with Banteng (Bos javanicus) is 0.061 whereas the furthest distance between BaliLombok 8 with Banteng (Bos javanicus) is 0312.
