A total of 423 quarters of 109 apparently healthy lactating crossbred cows (Sahiwal x Jersey) were screened for sub-clinical mastitis. Of these, 40 cows (36.69%) and 71 (16.78%) quarters were found culturally positive. As per the International Dairy Federation criterion, 58 (13.71%) were found to suffer from sub clinical mastitis. Relative frequency of various micro-organisms among 60 isolates, from the 58 apparently healthy quarters revealed isolation of Staphylococcus epidermidis (28) Staphylococcus aureus (22), Streptococcus agalactiae (6), Streptococcus dysgalactiae(3) and Streptococcus uberis (1). Two quarters harbored mixed infection. Cows found positive for sub-clinical mastitis were divided into three groups on the basis of antimicrobial sensitivity towards penicillin and cloxacillin. As many as 80 per cent of the quarters treated with Vetclox plus in group I were bacteriologically negative five days after withdrawal of therapy, whereas 70.58 per cent of quarters revealed bacteriological cure in group II cows treated with Pendistrin SH. Corresponding figure for treatment with Mastacure ™ in group III on day 5 post-treatment was recorded as 47.61 per cent However, on days 10 and 20 post-treatment, bacteriological cure rates in Mastacure ™ treated quarters of group III were found to be increased to 57.14 per cent and 66.67 per cent respectively, whereas no change in bacteriological cure rates were observed in groups I and II treated with antibiotics when compared with day 5 post-treatment values. No side effects of drug administration were observed in any of the groups of treated cows.
