The goal of the research was to ascertain changes in cholesterol level in Latvian Brown breed cows' milk with different fat content in summer and winter seasons. Twelve Latvian Brown breed cows were tested for the cholesterol level in milk in summer and eight cows in winter. The results showed that the cholesterol level in milk was ranging from 0.09 to 0.22 g l*[-1) in summer and from 0.08 to 0.17 g l*[-1) in winter. There were seasonal differences (feeding effect) in the cholesterol level and milk fat. Higher cholesterol content in milk was found in summer. In the winter season the cholesterol level decreased while fat content was substantially higher (p0.05). Correlative relations between cholesterol content and milk productivity traits were found higher in winter.
