K⁺ uptake in milk serum-derived vesicles sampled from morning milking of control cows and noon milking of the experimental cows, with and without the presence 10 μM of β-CN f (1–28)in the incubation medium. The effect of the presence of β-CN f (1–28) was significant at P < 0.001, whereas the effect of the source of the vesicles was significant at P < 0.01).
