A recent report (January 2019) from the KSDAE highlights the results of DNA analysis carried out on the dung of a wild bull Bornean Banteng in Kalimantan. http://ksdae.menlhk.go.id/info/5312/banteng-kalimantan,-spesies-baru?.html
This bull is part of a herd occupying the degraded grasslands of Padang Long Tua near Long Alango in the Kayan Mentarang National Park in East Kalimantan. The researchers found that despite reports of wild bulls mating with domesticated village cows (Bali Cattle) in the past there was no DNA evidence of introgression (hybrids) between the wild Banteng and the Bali cattle owned by villagers.
Recent DNA analysis carried out in Sabah indicates that the Bornean Banteng is genetically distinct from the the domesticated Bali Cattle of Java and the Banteng of continental SE Asia. The Bornean Banteng can therefore be described as endemic to Borneo with the scientific name of Bos lowii.
