For evaluation of annual dynamics the polynomial functions were determined for particular parameters with so degree as the values of R2 were higher than 0.5. For the graphical expression the positive relationship between lipaemia and daily milk production is clear at whole range of observed lipaemia (from 1.99 g/l to 3.89 g/l). As well the negative relationship between blood plasma lipaemia and proteins content in milk is clear. Negative relationship between the fat content and blood plasma lipaemia was observed from lipaemia 2.5 g/l, to this value the relationship was positive
