The present study was conducted to evaluate the antioxidant activity of milk from Vechur and Kasargod Dwarf cattle indigenous to the state of Kerala, India. Vechur cattle is registered as an indigenous breed as per National Bureau of Animal Genetics Resources whereas Kasargod Dwarf is labelled as ‘non-descript’. The antioxidant capacity of the milk samples was determined by the 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay method. The study revealed that the average antioxidant potential of Vechur and Kasargod Dwarf milk were 44.11 ± 8.60 and 48.75 ± 7.65% RSA respectively. The activity ranged between 33.35 to 63.70% for Vechur cow milk and 32.13 to 57.31% for Kasargod dwarf milk. The results of the study suggest that the enhanced radical scavenging activity of milk from native cattle varieties may be due to the variation in compositional parameters.
