The viscosity and adhesive strength of casein from the milk of 6 individual cows were determined on samples collected regularly over a period of 21 months. Three of the cows calved in autumn and 3 in spring. The viscosity of the casein from 5 of the cows showed a decline during lactation that was independent of the date of calving. It was therefore concluded that the decline in casein viscosity may be attributed to lactational rather than seasonal effects.
