A COMPARATIVE STUDY OF SOMATIC CELL COUNTS IN MILK FROM CROSS-BRED AND RATHI CATTLE WITH SUBCLINICAL MASTITIS

Taruna Bhati, A. K. Kataria

Abstract

The somatic cell count (SCC) is a measure of the number of leukocytes and epithelial cells in milk. An increase in milk SCC is an indication of mammary gland inflammation hence SCC can be used as a screening test to identify intramammary gland infections (IMI). In the present investigation, 85 milk samples collected from (31)HF crossbred and (54) Rathi cattle were subjected to somatic cell counting .Thirty eight samples ( 16 from H-F crossbred and 22 from Rathi cattle)which revealed presence of two lacs or more cells/ml were identified as cases of subclinical mastitis. The mean SCC in H-F crossbreds was higher (6.36 lacs/mL) as compared to that in milk from Rathi cattle (5.13 lac/mL). The range of SCCs varied between 2.07 - 22.56 lacs/mL in H-F crossbred cattle and between 2.56 -13.21 lacs/ml in Rathi cattle. The data indicated lesser variations in the native breed than in the crossbred animals which may be considered as an index of higher resistance of native breeds towards change in SCC due to various reasons
