Seasonal changes of milk components, proportion of rejected milk, bacterial counts and the relationship between milk fat and solid-not-fat (SNF) of farm milk were studied over a period of two years(1987-1988). The results obtained were as follows: 1. Mean values of milk fat, protein, lactose, SNF and total solid were 3.72, 3.19, 4.60, 8.68, and 12.40 % respectively. 2. A significant correlation coefficient exsisted between milk fat and SNF content (P$lt;0.01). The coefficient and regression equation in the first and second year were r=0.347, Y=7.637+0.2777X and r=0.292, Y=7.715 +0.254X respectively. 3. The incidence of rejected milk was 0.75% of total quantity of raw milk recieved. It was higher rejected milk percentage than other region of the mainland and was affected greatly by season. 4. Coli-form bacterial count of the raw milk samples showed 46.3%m were under 100,000 cfu/ml and 53.7% were over 100,000 cfu/ml. 5. More than 4 x 10^7 cfu/ml live bacteria were counted in the raw milk with 53.8 % of the farm surveyed.
