Scientists find Philippine native carabao and riverine buffalo as distinct species

Published Sep 19, 2024

Tridge summary

A recent study conducted by Filipino scientists has revealed that the two domesticated buffaloes in the Philippines, the carabao and the riverine buffalo, are in fact different species, not subspecies as previously believed. The research, published in the Philippine Journal of Science, confirms that the buffaloes have distinct DNA sequences and chromosome numbers, and highlights their noticeable physical differences. The carabao is smaller, has lighter skin and coat color, and is used mainly for draft work, while the riverine buffalo is larger, has curly horns, and is raised for milk and meat production. The researchers suggest that the carabao should be classified as Bubalus kerabau, and their findings could have implications for breeding programs. Future research will focus on the genetic relationships between these buffalo species.

The two domesticated buffaloes in the Philippines are different species, according to a study conducted by Filipino scientists. The Philippine native carabao or swamp buffaloes (Bubalus bubalis carabanensis) and riverine buffaloes (Bubalus bubalis bubalis) have traditionally been identified as subspecies of Bubalus bubalis, but researchers from the University of the Philippines—Diliman College of Science’s Institute of Biology (UPD-CS IB) and the Department of Agriculture—Philippine Carabao Center (DA-PCC) said the DNA sequences of the genes from both buffaloes are distinguishable and that their chromosome numbers are different. “These results corroborate the observed differences in their appearances. Swamp buffaloes can be identified by the white or light gray markings on their lower jaw and brisket, known as a chevron, as well as their lighter skin and coat color compared to riverine buffaloes. They are also smaller, weighing between 325 and 450 kg, and have crescent-shaped ...
