The major alteration in the milk composition due to mastitis includes presence of somatic cells (neutrophills, monocytes, macrophages and mammary epithelial cells), bactericidal and bacteriostatic compounds and certain enzymes. Antibiotic residue violation and presence of foodborn pathogens with/without their toxins is another threat of immense importance. These changes in the milk account for the deterioration of the milk quality, risk of health hazards and also its acceptance in the international market. Of all these components, milk somatic cells are the single most widely used indicator of the udder health and mastitis. Somatic cell count (SCC) is used as a system for measurement of milk quality internationally. Strict legislation for monitoring the minimum SCC level is followed to ensure healthy milk in most of the developed countries. This paper introduces the concept of ‘Clean White Revolution’ and reviews the importance of SCC as a measure to ensure hygienic milk production in India. It also emphasizes upon a need to strengthen the existing legislations concerned.

Abstract. The aim of this study was to determine the effect of somatic cell count (SCC) on milk yield and composition using a threshold value of 250 ∙103 cells/ml in dairy ewes of line 05. A total of 1 512 milk samples from udder halves were collected throughout milking periods at monthly intervals. In the present study milk composition (from halves of the udder) and daily milk yield (from udders) was examined in terms of SCC in ewe milk in three groups: from both halves of the udder below 250 ∙103 cells/ml, from one halves of the udder below 250 ∙103 cells/ml and from second half udder above 250 ∙103 cells/ml and from both halves of the udder above 250 ∙103 cells/ml. Milk yield from udders, somatic cell count in milk samples from udder halves and milk composition depended on the level of SCC recorded for halves of the udder. Somatic cell counts in milk from one or both halves of udders exceeding 250 ∙103 cells/ ml resulted in a statistically significant (P<0.01) decrease in daily milk production of ewes, by approx. 15.89 and 30.22 %, respectively. The analysis of variance showed also a significant effect of parity and stage of lactation of ewes on somatic cell count (log SCC) and milk composition from udder halves below 250 ∙103 cells/ml.
