abstract
The present study was conducted at the department of Livestock Production Management, Mumbai Veterinary College, Mumbai. For the present study twenty four floor swab samples and eighteen water sample from twenty four dairy farms in and around Mumbai were collected. The dairy farm were categorized as small (Animal less than 50), Medium (Animal more than 50 and less than 100) and Big (Animal more than 100). The floor sample and water sample were collected and were subjected to total viable count and most probable number analysis at the department of Veterinary Public Health, Mumbai Veterinary College, Mumbai. The results revealed non significant difference between the treatment groups for both floor swab and water analysis. The results pertaining to the presence of Staphylococcus, E.coli, Yeast and mould and Salmonella spp. showed the presence as 37.5,37.5 25 and 0% for big dairy farms whereas for the medium dairy it was 25,0,50 and 12.5% and that to for the small dairy farm it was 62.5,25,25 and 12.5% respectively. The water was also analysed for the MPN values, the result revealed that the big, medium and small dairy farm has 1, 3 and 1 potable water sample respectively which was good for drinking purpose whereas the other samples were non potable. There is a need to educate the dairy farmers to keep the floor and water hygiene to prevent the occurrence of disease at farms.
