Quality of the milk has a significant effect on the economic return and sustainability of the dairy farm. Present study was conducted to assess the milk quality of the New Zealand Farm, Ambewela, Sri Lanka with respect to milk instability and microbial activity. Alcohol test (to determine milk instability) for milk obtained from New Zealand farm, Ambewela in three times of the day from the lactating cows (164) in the herd was performed and cows with all three positive and all three negative results were selected for further analysis. The milk from the selected cows was subjected to Resazurin test (RT), Californian mastitis test (CMT) and Portable somatic cell count (PSCC) with three replicates. The alcohol test resulted 34 and 86 all positive (P) and all negative (N) for three trials, respectively. A significant difference was observed for both Resazurin test and somatic cell count test (P = 0.029 and P=0.020 respectively) among the tested groups (P and N). P and N groups showed 38% and 11% positive results respectively for CMT. In conclusion, study revealed that the instability of the milk studied was relatively high and the alcohol test results were more precisely analyzed with a combination of RT, CMT and PSCC test. Hence it can be suggested that subclinical mastitis induced microbial activity has caused the instability of raw milk in New Zealand Dairies, Ambewela.
