The present investigation was carried out to investigate the effect of biometric characteristics of udder and teats with milk Somatic Cell Count which are important for farmers, manufacturers and consumers. For this study we collected 50 ml milk from 150 Indigenous lactating cattle breeds viz., Kankrej, Sahiwal and Rathi cattle (50 from each breed) reared under similar management conditions at university cattle farms located in Bikaner city of Rajasthan, India. Udder and teat morphometric parameters, i.e. Normal and pendulous shape of the udder, depth of udder, flat, inverted and pointed shape of teat-end, length of teats were measured before milking. We observed the significant (P<0.05) effect of udder shape, udder depth, teat end shape and teat length on SCC in Kankrej, Rathi and Sahiwal breeds of cattle. In conclusion, the udder and teat morphometry characteristics viz., udder shape, udder depth, teat end shapes, teat length have some degree of association with somatic cell count and prevalence of subclinical mastitis in indigenous breeds of cattle. The selection of dairy animals is usually based on body confirmation. Udder and teat are primary boy confirmation for dairy animals. The present study is useful for farmers during the selection of dairy animals.
