The present experiment was conducted to study the milk quality of indigenous cattle which are important for farmers, manufactures and consumers. For this study, we have collected 150 milk samples of three different indigenous cattle breeds viz. Kankrej, Sahiwal, and Rathi from semi-arid region of Rajasthan, India. The samples were evaluated for the milk fat, protein, lactose, solid not fat (SNF), somatic cell count (SCC), pH, electric conductivity and freezing point, and observed the relationship of breed, stage of lactation, parity and body condition score (BCS) with their milk constituents and freezing point. Total Protein, freezing point and electric conductivity of milk differed significantly (P<0.01) among the breeds. Freezing point, fat and protein contents of milk were significantly affected by parity and body condition score of the cattle. From this study it can be concluded that the milk constituents differs among the breeds of indigenous cattle and affected by many non genetic factors, therefore these are the factors which influences the quality of milk in different Zebu cattle breeds.
