Abstract: Mastitis, a disease of multiple etiology, had been recognized for more than a century, and still continues to be an evergreen cause of economic loss to the dairy industry and is the costliest problem all over the world where dairying is practiced. The distribution of mastitis incidence varies from country to country. Subclinical mastitis more prevalent than clinical mastitis and its prevalence varied from herd to herd and place to place. Subclinical mastitis (SCM) is most important due to its negative impact on the economy throughout the world dairy industry. Incidence of bovine SCM was studied on dry pregnant cows of organized and unorganized farms in an around Khanapara, Guwahati, Assam. Diagnosis was based on Somatic Cell Count (SCC). A total of 30 cows were examined, of which 6 cows belonged to an organized farm and rest 24 cows to unorganized farms. Four cows (13 quarters samples) from organized farm were found positive for SCM. The incidence of SCM cow-wise was 66.67 per cent and quarter-wise 54.17 per cent. On the unorganized farms, all the milk samples from 24 cows (83 quarter samples) were positive for SCM and the incidence was 100 per cent both cow- wise and quarter-wise. The overall percentage of incidence cow-wise was 93.33 and quarter-wise 90.26 per cent. High incidence of SCM on the organized farm is implicated to small sample size, whereas on the unorganized farm the management practices leading to stress may be explained as the reason of such high incidence of SCM.
