Abstract: Vechur and Kasargod Dwarf cattle are indigenous to the state of Kerala, India. Vechur cattle is registered as an indigenous breed as per National Bureau of Animal Genetics Resources (NBAGR) whereas Kasargod Dwarf is labelled as ?non-descript?. Limited information is available on the compositional characteristics of milk from these cattle. In the present study, milk proteins from Vechur and Kasargod Dwarf cattle were characterized to evaluate the protein fragments. The electrophoretic pattern of these milk samples showed the presence of seven protein bands, viz., Lactoferrin (Lf) (76 KDa), immunoglobulin (Ig) (66 KDa), ?-S1caseins (?-S1-CN) (23KDa), ?-S2caseins(?-S2-CN) (21KDa),?-casein(?-CN) (24KDa), ?-lactoglobulin(?-Lg)(18KDa) and ?-lactalbumin (?-La) (14 KDa).
